A study was conducted to reveal the phenology and pollen studies in Madhuca indica Gmel. The study revealed that the synchronous flowering of Madhuca indica Gmel. started during first week of March and ends towards first week of May with a peak period of flowering from last week of March to second week of April. Flower bud development took 32.55 to 34.18 days to anthesis. Microscopic studies revealed spherical pollen grains with a single germ pore. The maximum anthesis and anther dehiscence were observed between 06:30 to 07:30 a.m. and 06:00 to 07:00 a.m. respectively. The average maximum pollen viability on the day of pollen collection was found to be 94.12 and 92.33%, respectively stored at room temperature and at -10⁰C (±2). Out of four 5, 10, 15 and 20% sucrose concentrations applied, in-vitro pollen germination was found maximum (44.82%) at 15% sucrose concentration medium after twenty four hours of observation period.

Vernonia cinerea is an important medicinal plant which is frequently used in the traditional system of medicine. Due to over exploitation its availability in the natural habitat has become limited.  In order to overcome this problem, a viable protocol for large scale multiplication of the species through callus induction and regeneration and somatic embryogenesis has been standardized.

Present study emphasised for the development of MBFs on wastelands in India. The development strategy of MBFs on wastelands need to adopt in plain and hilly area separately. For canopy strata-wise MBFs development in both category of wastelands in India, author has prepared a list of about 50 plant species for each category which consisted a habit namely, tree, shrub, herb and climber for fulfil needs of local people. Simultaneously, author also emphasised that the man-made and natural monoculture forests should be converted in MBFs gradually and allow their natural regeneration, protect from fires and biotic disturbances. No doubt, MBFs will not only provide renewable plant resources to local community but this practice also helpful for the conservation of biodiversity, increase soil fertility, control soil erosion, landslides, proper regulate hydrological cycle, reduce environmental degradation and mitigation of climate change also.

This Paper deals with taxonomy, distribution, ecology and traditional uses of Acanthus leucostachyus from Assam.

A field work was undertaken to study the physico-chemical and biological parameters of treated distillery effluent and the effect of various concentrations such as (0, 5, 10, 20, 40, 60, 80 and 100%) on plant growth i.e. seed germination, root length, shoot length, length of leaves, chlorophyll content in the Achyranthes aspera. The effluent could not be directly applied to the field because of its excessive TDS, BOD and COD values and large quantities of soluble and suspended organic matter. Effluents was filtered through muslin cloth and diluted 2.5 times and there after various dilutions were prepared by diluting it with tap water.

The present study was conducted with a view to access the present status of diversity of herbaceous layer of Gurez valley. The study area is highly rich in non-timber forest products like Saussurea costus, Artemisia spp., Podophyllum hexandrum, Aconitum heterophyllum, Jurinea macrocephala and many other such plants which are very important for their high medicinal value. An attempt has been made to study the phytosociological status of the herbaceous layer of the Gurez valley.

This paper concentrates on the reasons for the loss of Palmyrah tree in Kudiraimozhi theri and some measures are also suggested to conserve Palmyrah.

A technology has been developed for weeding in between wide row crops such as Jatropha and Eucalyptus by using tractor operated rotovator with appropriate modifications in the traction wheels of the tractor. The machine is capable of weeding 0.20 ha/h with 97 per cent weeding efficiency and 83 per cent field efficiency. Cost of replacing the tractor rear pneumatic wheels with iron wheels comes to Rs.14,000/-. Cost of weeding by this technology comes to Rs.1700/ha. When the wide row crops are planted in check row planting (rows in both directions), the equipment can be used for weeding and interculture in both directions.

This communication presents the results of revisionary studies on the genus Eria Lindl. (Orchidaceae) in India, with details of its systematic position, classification, generic circumscription and distribution. Artificial key to all the 60 taxa belonging to 13 sections (57 species, 3 varieties) found in India has been provided. All taxa are enumerated with citation, synonymy, type, distribution and respective authentic specimen(s). Eria extinctoria (Lindl.) Oliv. and Eria pulchella Lindl. have been recorded for the first time from India. Whereas the invalid Eria jengingensis Hegde has been validated as Eria hegdei D.K. Agrawala & H.J. Chowdhery; Eria apertiflora Summerh., Eria tiagii Manilal et al., Eria laniceps Rchb.f. and Eria sikkimensis D.M. Bajracharya & K.K. Shrestha were found conspecific with Eria bipunctata Lindl., Eria microchilos (Dalzell) Lindl., Eria lasiopetala (Willd.) Ormerod.  and Eria muscicola (Lindl.) Lindl. respectively. Several species have been recorded from new geographical localities and some have been collected for the first time after their type collection. A list of taxa with doubtful occurrence or excluded from India is also provided at the end.

In this paper a total of 286 trees, shrubs and climbers belonging to 69 families and 204 genera have been enumerated.

Growing fruits naturally in the forest have served as food to human being for millennium and will continue to serve, until unless these fruit producing species become extinct because of the pressure of human population. Present paper describes some species and appeals for using them in fruit breeding programs.

Study was conducted in Rissa Khad watershed of Mandi District, Himachal Pradesh to assess the diversity, endemism and economic potential of wild edible plants. A total of 237 wild edible plants belonging to 119 genera and 94 families were recorded. The species were also analysed for nutritional and medicinal values to find out economical potential.
