Abstract: The quantitative analysis of plant diversity of semi evergreen forest of Hollongapar Gibbon Wildlife Sanctuary in upper Assam was investigated during 2010-2011 by random plot sampling method. A total of 202 plant species (75 trees, 23 shrubs, 85 herbs including herbaceous climbers, 9 lianas, 3 bamboos, 6 rattans and 1 palm) belonging to 169 genera and 87 families were recorded from the sanctuary. Vatica lanceaefolia Bl., a critically endangered species, emerged as the dominant tree species. The highest plant density and diversity were found in herbaceous species. Shannon-Wiener diversity index (1.93 to 3.81) and Simpson ' s index (0.05 to 0.17) were within the range reported for different Indian tropical forests which indicated that the sanctuary is a species diverse forest. Plant species diversity and their quantitative features recorded from the present study may provide baseline information for conservation and management strategies of the present forest.

Keywords: Bombusa polymorpha, Splitting
Abstract: The study was investigated the splitting failure of Bambusa polymorpha through two testing methods: fracture test and edge bearing test. This is mainly done with an aim to generate preliminary data for studying splitting behaviour of Bambusa polymorpha. The fracture test appears to yield both reliable and accurate results, but so far only one geometry has been tested for split pin test. It has yet to be shown whether a change in the pin diameter, the culm diameter, or the size of the initial crack will have any effect on the stress intensity obtained. It is further proposed that selecting a pin diameter similar to that used for bolted connections may help to develop appropriate values for design. In edge bearing test there is no significant differences were found in considering specimen with different length. As the engineering interest in bamboo is recent, there are many areas still requiring further investigation. The fracture test appears to yield both reliable and accurate results, but so far only one geometry has been tested. In edge bearing test there is no significant differences were found in considering specimen with different length.

Abstract: Haldu (Adina cordifolia Roxb). is a naturally grown tree in moist deciduous forests of Bangladesh and has diversified uses. But the population of the species has become threatened due to over exploitation. The large scale propagation of this species is quite difficult through sexual and asexual methods. So to rescue this important species from going to be threatened, attempts were made to develop an efficient protocol through in vitro culture that would maintain and propagate it in large scale. The shoot tips were used as explants and culture established in MS media supplemented with different concentration of BAP and combination of BAP and NAA 0.5 mg/l. It was observed that MS media supplemented with BAP 1.0 +NAA 0.5 mg/l was more effective for shoot production and development. The present study also showed that IBA was more suitable than NAA where IBA 1.0 mg/l was found more effective for root induction. After sequential hardening, rooted plantlets were successfully transferred to soil and the plantlets were grown luxuriously.

Abstract: 22 progenies of seedling seed orchard Pongamia pinnata were evaluated for seed morphomatric traits, germination traits and seedling at the age of 8 year old provenance trial. Patterns of genetic variation in Pongamia pinnata (L) Pierre, a humid tropical oilseed leguminous tree, were evaluated at the population level. Analysis of variance revealed significant differences among progenies in all studied attributes at nursery stage. All seed morphometric traits were positively correlated among themselves and with germination traits viz., germination per cent, germination value and germination index, except days of initiation of germination and germination energy but no significant correlation was observed with seedling growth traits at nursery stage. The genetic parameters for seed morphometric traits, germination and seedling growth also showed a wide range of variations. Heritability value for different traits was varied from 79 to 96 % for seed morphometric traits, 63-84 % for germination traits, 83 % for shoot height and 62 %for volume index and 56 % for collar diameter. Seed weight and seed volume showed high heritability value coupled with more genetic gain, which indicate the presence of good amount of heritable additive component in both traits.

Keywords: Biomass, Growth, Carbon storage, Multipurpose trees.
Abstract: Growth rate and carbon storage in selected multipurpose trees were assessed to identify the fast growing trees and also those that store high carbon in their biomass. Among the plant parts studied, wood stored the higher carbon (56.38 mg/g), leaf stored the minimum (53.27 mg/g) and bark had a medium storage (54.06 mg/g).The fast growing tree with maximum increase in diameter and with maximum biomass production was Syzigium cumini (4.42 cm) and slow growing tree was Milletia pinnata (0.82 cm). Syzigium cumini stored maximum carbon (2.71 kg/year) and biomass (4.9 Kg/year). Milletia pinnata stored the minimum carbon (0.67 kg/year) and biomass (1.24 Kg/year). Parkia biglandulosa (3.97 cm), Khaya senegalensis (3.7 cm), Tabebuia rosea (3.5 cm), Peltaphorum pterocarpum (3.17 cm) are also considered as fast growing trees. Trees with fast growth rate and also those which store high biomass carbon are recommended for planting as avenue and ornamental trees as a step to mitigate atmospheric carbon concentration.

Abstract: Tephrosia candida is an excellent nitrogen fixing green manure yielding species, which produces hard-coated and green black colour seeds. Seed has physical dormancy due to hardiness of testa. Suitable pretreatment to break the dormancy was investigated. Germination was enhanced from 22.77 percent (untreated) to 90.14 percent (mechanical scarification). Although, mechanical scarification treatment gave early, uniform and highest germination, but it is not practicable on large-scale. Therefore, hot water soaking for 24 hours or scarification by sulphuric acid for 15 minutes is recommended.

Abstract: Effect of crown position study revealed that the cone length (22.14 cm), cone diameter (2.88 cm), number of fertile scales/cone (130.02), total number of scales/cone (141.58), number of seeds/cone (254.04) and weight of seeds/cone (13.04 g) were highest for the cones which were collected from middle crown. The seed length (11.80 mm), width (5.02 mm), thickness (2.99 mm), fresh (5.35 g) and dry weight of 100 seed (4.07 g) were also found maximum of seeds from middle crown. Seed germination was also maximum (68.25%) from middle crown cones under laboratory condition and was significantly higher than the germination of seeds of lower crown. The germination value differed significantly only with lower and upper crown. The maximum germination, germination value, germination index and speed of germination under nursery condition were obtained from the seeds of middle crown but the value of these parameters was less than the values obtained under controlled conditions. The collar diameter and shoot length obtained from the seed collected from middle crown showed a significant difference with the collar diameter and shoot length of lower crown position. However, the seedling dry weight from middle crown differed significantly from upper as well as lower crown position.

Abstract: Pudukkottai is a small district which had a lot of rich forests earlier. Later, all these thick forests were cleared for eucalyptus plantation to feed the paper and rayon factories. Much of the biodiversity has been lost due to the monoculture of eucalyptus. There a quite few sacred groves in this district which still harbor a substantial number of the native flora and fauna and continue to offer the ecosystem services. But many of them are slowly getting degraded due to human intrusion, cattle grazing and invasion by exotic species like Prosopsis. Conservation of these sacred groves helps in conserving biodiversity and also restores the valuable ecosystem services. Conservation measures should aim to improve the conservation status of existing sacred groves and to replicate these in other areas available for plantation.

Abstract: Heavy metal contamination in crops is a worldwide problem that requires accurate and timely monitoring. This study is aimed at improving the accuracy of monitoring heavy metal stress levels in rice utilizing remote sensing data. An assimilation framework based on remote sensing and improved crop growth model was developed to continuously monitor heavy metal stress levels over the entire period of crop growth based on the growth law of crops and the stress mechanism. Compared with other physiological indices, dry weight of rice roots (WRT) was selected as the best indicator to estimate heavy metal stress levels. The World Food Study (WOFOST) model, widely used for the description of crop growth, was improved by incorporating stress factors with overall consideration for the changes in physiological status under heavy metal stress. Three scenarios were put forward based on the stress factors fDTGA and f CVF-*, which respectively; correspond to the daily total gross assimilation of CO2 and carbohydrate-to-dry matter conversion coefficient, and were analyzed for their efficiency of simulating WRT. A method of assimilating the leaf area index (LAI) retrieved from remotely sensed data into the improved WOFOST model was applied to optimize f DTGA and f CVF. The results suggested that the scenario using both factors can simulate WRT under heavy metal stress more accurately, with a relative percent error (RPE) lower than 14 %. Based on the RS-WOFOST assimilation framework, continuous spatial-temporal evaluation of heavy metals stress levels based on WRT can be accomplished.

Abstract: Iraq contains the Great Mesopotamian alluvial palin of the Euphrates and Tigris rivers. Its regional vegetation phonological patterns are worthy of investigation because relatively little is known about the phenology of semi-arid environments, and because of their inter-annual variation is expected to be driven by uncertain rainfall and varied topography. The aim of this research was to assess and map the spatial variation in key land surface phenology (LSP) parameters over the last decade and their relation with elevation. It is the first study mapping land surface phenology during last decade over the whole of Iraq, and one of only a few studies on vegetation phenology in a semi-arid environment. Time-series of Moderate Resolution Imaging Spectroradiometer (MODIS) normalized difference vegetation index (NDVI) data at 250 m spatial resolution and 8 day temporal resolution, were employed to map the spatial variation in three LSP parameters for the major vegetation types in Iraq during 2001-2012.LSP parameters were defined by inflection points after smoothing the vegetation phonological signals using the Fourier technique. The estimated key LSP parameters indicated that the relatively shorter length of season (LOS) in the north of Iraq resulted from a delayed start of season (SOS). Greater spatial variation occurred in the SOS than end of season (EOS) ,which may be due to the spatial distribution of rainfall and temperature as a function of elevation. A positive correlation was observed for SOS and EOS with elevation for all major land cover types with EOS producing the largest positive correlation (R2=0.685, R2=0.638 and R2=0.588, p<0.05 in shrubland, cropland and grassland, respectively). The magnitude of delay in SOS and EOS increased in all land cover types along a rising elevation gradient where for each 500 m increase ,SOS was delayed by around 25 or more days and EOS delayed by around 22 or more days, except for grassland. The SOS and EOS also varied temporally during the last decade, particularly the SOS in the lowland, north of the country where the standard deviation was around 80 to 120 days, due mainly to the practice of crop rotation and the traditional biennial cropping system. Thus, the results of this research emphasize the effect of elevation on key LSP parameters over Iraq, for all major vegetation types.

Abstract: Forage is among the essential ecosystem services provided by tropical savannas. Expected changes in climate and land use may cause a strong decline in herbaceous forage provision and thus make it advisable to monitor its dynamics. Spectroscopy offers promising tools for fast and non-destructive estimations of forage variables, yet suffers from unfavourable measurement conditions during the tropical growing period such as frequent cloud cover and high humidity. This study aims to test whether spatio-temporal information on the quality (metabolisable energy content, ME) and quantity (green biomass, BM) of West African forage resources can be correlated to in situ measured reflectance data. We could establish robust and independent models via partial least squares regression, when spectra were preprocessed using second derivative transformation (ME: max.adjusted R2 in validation (adjR2VAL = 0.75, min.nRMSE=9.4 %). Reflectance data with a reduced spectral range (350-1075nm) still rendered satisfactory accuracy.
Our results confirm that a strong correlation between forage characteristics and reflectance of tropical savanna vegetation can be found. For the first time in field spectroscopy studies, forage quality is modeled as ME content based on 24-h in vitro gas production in the Hohenheim gas test system and crude protein concentration of BM. Established spectral models could help to monitor forage provision in space and time, which of great importance for an adaptive livestock management.
