Poplar is a fast growing tree being recommended for Agroforestry System. Studies indicated that the Poplar based Agroforestry System is not getting momentum in Central part of Uttar Pradesh. Realizing the necessity of growing population the present investigation was conducted during the year, 2004 and 2005 at Forest Research Institute, Kanpur, Uttar Pradesh. It is revealed from experimental finding that the Poplar clone S7C4 showed the highest plant height closely followed by S7C2 whereas highest collar diameter with Poplar clone S7C2 closely followed by S7C4. The highest number of branches in main shoot was recorded by S7C15 followed by G-48 and Udai whereas it was lowest with G-3 followed by L-52. The Pant Poplar-5 possesses the highest leaf area index followed by S7C2 and G-48 and it was lowest with D-121. The poplar clone G-48 showed the longest leafless period whereas lowest duration was with Pant Poplar-5. The lowest crown diameter was recorded with G-3 followed by S7C2 while it was highest with G-48 followed by Udai.

Genetic variation for different parameters in Dendrocalamus hamiltonii (Maggar Bans) was conducted among 23 genotypes of Himachal Pradesh, identified as plus bamboo stands. Observations on ten characters viz., culm height, diameter, internode length, no. of new sprouts, no. of culms, clump girth, leaf length, leaf breadth, culm wall thickness and biomass were recorded.  Evaluation of bamboo (Dendrocalamus hamiltonii) at the age of three years indicated significant differences for all the characters. Estimates of heritability in broad sense were observed generally high for leaf breadth, biomass, leaf length, culm height and internode length. Growth characters such as plant height, diameter, culm wall thickness, bole thickness were found significantly and positively correlated with biomass.

The present study is an effort to analyze the effect of Agrogreen, one such formulation on the growth and flowering of Rainbow Ginger (Curcuma aurantiaca Zijp.), an important potential ornamental ginger that is common in South and South East Asia. Agrogreen treatment resulted in healthy and uniform growth of the plants. The treated plants showed reduced plant height and compact habit making them dwarfer, healthier and more attractive. Flowering started earlier producing inflorescences with more compactly arranged bracts and flowers.  The plants became more vigorous with uniform flowering.

Sawdust of the timber from saw mill is one of the lignocellulosic materials which can be utilized for the preparation of the particle board. In this study, the saw dust of Teak (Tectona grandis), Neem (Azadirachta indica), Baheda (Terminalia belerica), Mango (Mangifera indica) and Babul (Acacia nilotica) were used for the preparation of particle boards with resin content of 6, 8, 10, 12 and 14%. Subsequently, they were tested for different physical properties according to Indian Standard IS: 3087. The results show that Mango and Teak sawdust can be utilized for producing medium density particle boards. Satisfactory boards were prepared from Mango (Mangifera indica) and Teak (Tectona grandis) sawdust using 12% phenol formaldehyde resin met the requirement in respect of physical properties as specified in IS: 3087 (1985).

Dried plant material was subjected to soxhlet extraction using seven different solvents in the increasing order of their polarity. Phytochemical screening showed the presence of alkaloids, proteins, carbohydrates, cardiac glycosides, saponins, tannins and phenols, triterpenoids in different extracts of the plant while the absence of flavonoids, steroids, fats and oils in all the extracts.

Investigation on biomass and nutrient uptake of Jatropha curcas L. as affected by various bio-fertilizers was carried out which comprised of eight different bio-fertilizer inoculants as treatments with three replications in Randomized Block Design. Among the different bio-fertilizers, T₇ (Azospirillum+PBN-1+VAM) proved best for fresh weight and dry weight of leaves, stem, root and whole plant. The same treatment also showed the increasing rate of nutrient uptake by plants and increased the total Nitrogen, Phosphorus and Potash status in the soil. So, from ecologic point of view it is beneficial due to combine effect of biomass and nutrient uptake in rhizosphere.

The present paper highlights the uses of Cyperus bulbosus Vahl as food by the villagers of Kanam Puchikadu, a small village near Tiruchendur, Tuticorin district, Tamil Nadu.

The present study was under taken to identify best spacements of Casuarina equisetifolia L. for its growth and development as well as nutrient status of soil in South Gujarat condition. The experiment was laid out in randomized block design (RBD) with six replications. The composite soil samples were taken at upper (0-45 cm) depth of the soil. Among all the spacements of Casuarina equisetifolia, 2.0 x 2.0 m spacing recorded maximum impact on the status of major (266.00, 59.62 and 441.59 kg ha^-1, respectively for N₂, P₂O₅ and K₂O) and micro (19.64, 45.58, 1.21 and 1.35 mg kg^-1, respectively for Fe, Mn, Zn and Cu) nutrients as well as organic carbon content (1.13 %) in soil. The needle fall (0.65 kg/m²), thickness of needle fall (7.9 cm) and tree height (20.44 m) were recorded maximum in T₁ (2.0 x 2.0 m). While, girth at breast height (78.75 cm) and crown width (3.90 m) were recorded significantly maximum in T₄ (8.0 x 2.0 m) spacing.

Twenty genotypes of Madhuca indica Geml. distributed over different sites/locations of district Allahabad and adjoining areas in Uttar Pradesh, in their natural range were investigated for the pattern of field environment genetic variability and association analysis in Madhuca indica. The results revealed, higher values for phenotype coefficient of variation as compared to genotypic coefficient of variation in corresponding germination and seedling growth characters, indicating that the characters are greatly influenced by the field environment. The heritability and expected genetic gain were also observed to be high to moderate for these characters. There is wide scope for early screening of the genotypes because of the positive and significant correlation at 5% level of significance among germination and seedling growth characters with each other except for few characters times with each other such as internodal length with number of leaves per seedling, number of leaves with dry weight of shoot, fresh weight of root and total biomass of seedling. Respectively as such genotypes S₂₀, S₁₂, S₉ and S₁₉ showed good performance as compared to other genotypes and are recommended for further genetic improvement programme in this species.

Polystichum stimulans (Kunze ex Mett.) Bedd. is a unipinnate lithophytic fern. Plant with unusual 3-4 times divison of frond was collected from Rohru, Shimla (H.P.). The possible cause of unusual division of frond might be due to cell necrosis and which has caused long cracking of apical meristimatic tissues resulted into the division of rachis to several times.

Madhuca longifolia var. latifolia (Roxb.) Chev. is an important multipurpose tree generally planted in rural area. Polyembrony in the said variety was not reported earlier. The total per cent germination of seed was 91% (546 seedlings), however polyembrony were observed in 4.76% (26 seedlings). Out of these polyembronic seedlings, there were 12 twins, 9 triplet and 5 multiple shoot seedlings. Polyembronic seedlings showed shorter root and shoot length as compared normal seedlings.

The present study showed the improvement of S. torvum plant through the effect of different light on pollen germination, pollen tube growth, fruit set, fruit size and fresh weight of ripened fruits. The pollen grains of S. torvum were germinated on a basal medium and study the effect of blue, green, white, yellow and red light under in–vitro condition. Percent of pollen germination and tube growth were lesser in the dark condition than the white light but maximum by the red light in 4 and 5 hrs incubation.  Based on pollen germination and tube growth variability in-vitro from different light. Hundred long-styled flowers (before anthesis) were chosen randomly for each colour and after hand pollination obtained the per cent of fruit set, size and weight of ripened fruit was lesser in the dark as compared to other lights and aforementioned these values were maximum under the red light. Thus, the present work   emphasised that the red light should be used for the improvement of fruit size in S. torvum.

Albinism is an important natural event that influences seedling development in most of the tree species, and it is mostly governed by homozygous recessive genes. A survey was conducted to ascertain the natural regeneration status of Bambusa bambos in the established LTI (Long Term Tree Increment) Plot located in Karka range, Dharwad Circle, which had gregarious flowering was observed in 2008-2010. A well-established albinic variant of B. bambos was observed on the forest floor amongst other established B. bambos seedlings, having a height of 90 cm with good rhizome development.
