Abstract

The present study was carried out to find the effect/ Influence of media on germination. The seed was sown in different media such as top of paper (TP), between paper (BP), sand (S) and top of sand (TS). The maximum germination per cent and high vigour index was recorded in the top of paper (TP) medium. Being a large size seed, it gave good results in sand (S) and top of sand (TS) also. It is evident from the results that the germination value of seed has little differences in both the media such as top of paper (TP) and top of sand (TS). Sand it self also proved a good medium and inexpensive other than. So, it is recommended that sand is good medium for testing the seed of Mesua ferrea in controlled condition.

Abstract

Source variation study of Sapindus mukorossi Gaertn. was undertaken to identify the superior seed sources for production of quality seedling. Thirteen seed sources sampled from different locations in Himachal Pradesh State. Variation for most of the studied characters indicated non-clinal pattern. On average, the population of Deothal (Rajgarh Forest Division), Majheen (Dehra Forest Division) and Naina Tikker (Rajgarh Forest Division) were found to be the best on the basis of weight, germination per cent and vigour index of seed as an important criterion for delineation the superior seed source. This preliminary investigation will be useful for further improvement of the species for better productivity.

Abstract

Phyllanthus amarus is an important medicinal plant commonly known as Bhumyamalaki, belongs to family Euphorbiaceae. In the nursery raised seedlings of P. amarus nitrogen and phosphorus treatments were applied as: T₀ Control, T₁, 30 kg N/ha,T₂, 40 kg N/ha, T₃, 50 kg N/ha, T₄, 30 kg N +50 kg P/ha, T₅, 40kgN +50kgP/ha,T₆,50kgN +50kgP/ha. The best results were recorded in T₄ (N30^∗P50) treatments as compared to others. The plants treated with N30^∗P50 had highest plant height, number of branches, collar diameter, fresh and dry weight of shoot andhighest biomass.

Abstract

Diploknema butyracea is a fast growing multipurpose tree species belonging to family Sapotaceae. Seeds of D. butyracea were stored for different storage period at ambient condition and various seed and seedling parameters were studied. The investigation revealed that seeds of this species are short - lived. Keeping in view the most desirable characters viz., germination per cent, germination value, seed weight, seed value and seed vigour of fresh seed lot were determined among all other storage periods at ambient condition.

Abstract

The effects of seasons and ischolar_maining hormone on air layering were investigated in Ficus krishnae and Ficus auriculata. Trials were conducted in three different seasons, viz. premonsoon, monsoon and post-monsoon using Indole Butyric Acid (IBA) ischolar_maining hormone (100, 300 and 500 ppm). Results revealed that IBA enhanced the ischolar_main initiation and induced ischolar_maining in a shorter duration. Air layering trials in pre-monsoon season under 500 ppm IBA treatment exhibited maximum ischolar_maining percentage followed by monsoon and post monsoon season.

Abstract

The allelopathic study on silver fir and spruce showed that leachates of humus have inhibitory effects on seed germination and on radicle and plumule growth; however, litter leachates have no such pronounced effect. Foliage leachates of Sarcocoocca saligna, Viburnum nervosum and ferns (understorey plants) have more inhibitory effects on seed germination and radicle growth. It seems that leachates of fern and Viburnum nervosum are mainly respousible for very less germination on forest floor as reported in fir and spruce forests. There is no self intoxicity on germination and early growth in silver fir and spruce. The research concludes that humus and foliage of specific plants are responsible for regeneration failure in these conifers and not litter as supposed till date.

Abstract

The present investigation was carried out on seedlings evaluation in Diploknema butyracea (Cheura) under laboratory condition. During the course of test, the nature of germination was epigeous and the normal and abnormal seedlings were observed 91 and 9 per cent respectively. Ten categories of abnormalities were also found in this species.

Abstract

Quercus floribunda (Moru oak) (Local name Tilonj) is an important element of western and central Himalayan vegetation. Lopping practice is very common in the forests and plantations especially near the habitation. Q. floribunda tree is lopped for fodder, which is the most appreciated among all oaks. However, heavy and indiscriminate lopping continues throughout the year which results pole like appearance of the trees with scanty leaves. Lopping of Q. floribunda results in poor production of acorns. The study suggests that there is need to understand the effect of lopping on acorn production to have sustainable lopping levels.

Keywords

Abstract

Forest fire is recognized as one of the major natural disaster, damaging huge forest and grassland areas worldwide. Fire can change plant composition, devastate biomass, alter soil physical and chemical properties and decrease nutrient pools. In recent years, Blue Pine (Pinus wallichiana) forests in South Kashmir are experiencing a heavy loss due to fire with respect to damage to undergrowth and disturbance in soil nutrient status. An assessment of damage in terms of ecological and economic attributes due to fire is deemed to be much. The frequency of fire is rising as biotic pressure on forest resources. This study demonstrates assessment of soil macro-nutrient alteration on sites on burnt with unburnt sites. The study sites are in South circle of Kashmir division in Jammu and Kashmir State of India. Our samples show 60% less soil carbon at 0-30 cm depth in burnt sites against their respective unburnt sites, Available soil nitrogen concentration was 35.28% lower on burnt sites, Available soil phosphorus was 38.89 % higher in burnt than unburnt sites and available soil potassium was 29.66 % higher on burnt sites in comparison to unburnt sites. Some implications of these results for forest managers are discussed. Organic carbon and nitrogen decreased in burnt areas while as potassium and phosphorus concentration witnesses an increase in burnt sites.

Abstract

The present study reports results vegetation survey of naturally occurring plant species found at Panchpatmali bauxite mine area at its undisturbed state and also after plantation without mining for bauxite and at rehabilitated sites of various ages after bauxite mining. Altogether 9, 12 and 23 shrub species and 43, 34 and 113 herb/lianas species were recorded during pre-monsoon period in virgin area, unmined area and rehabilitated over burden (OB) area, respectively. These figures were 9, 13 and 24 for shrubs, and 68, 51 and 163 for herb/lianas during post-monsoon period in virgin area, unmined area and rehabilitated over burden (OB) area, respectively. A total of 225 species belonging to 56 families were recorded from the study area.

Abstract

Trees are known to maintain soil organic matter and nutrient cycling through the addition of litter and ischolar_main residues into the soil. There is a large potential of sequestering carbon in soil and vegetation by adopting suitable agroforestry systems. The present investigation was conducted during January-June 2007 at Poanta valley of Himachal Pradesh, located at an elevation of 350 m amsl. Six agroforestry systems were selected viz. hortipastoral system (HP) (Mango + natural grasses), silvi-pastoral system (SP) (Dalbergia sissoo+ natural grasses), agri- silviculture system (AS) (Sal + wheat), horti-silvipastoral (HSP) (Mango+ Poplar + natural grasses), Pure Forest (F) (Sal), natural grass land (NG) (pure grasses). At 0-20 cm depth, soils under natural grassland was having higher bulk density (1.28g cm^-3 ) among all the systems while lowest bulk density (1.16 g cm^-3 ) was observed under forest. In 20-40 cm depth, the results also showed significant variation at 5% level of significance. Soil organic carbon (SOC) at the soil depth 0-20 cm was highest under forest (3.64 %) while silvi-pastoral system showed the lowest (1.30 %). In general, SOC pool in the 0-20 cm layer was quite higher than that of 20-40 cm layer. The total SOC pool for different Agroforestry system followed the decreasing order as PF (1373.7 Mg ha^-1) > HSP (719.6 Mg ha^-1) > AS (697.3 Mg ha^-1) > NG (696.5 Mg ha^-1) > HP (646 Mg ha^-1) > SP (599.10 Mg ha^-1).
