Survival and growth of seedlings of Rudraksh (Elaeocarpus ganitrus) under varied canopy conditions after transplant
An experiment was carried out to study the survival and growth of the nursery seedlings of Rudraksh (Elaeocarpus ganitrus) transplanted in the forest stands having dense, sparse and open canopy. The transplants exhibited better growth in terms of shoot length, collar diameter, leaf number and leaf area and survival in dense than in sparse and open canopy. The pathogen attack on seedlings was mo...
متن کاملEstimates of forest canopy height and aboveground biomass using ICESat
[1] Exchange of carbon between forests and the atmosphere is a vital component of the global carbon cycle. Satellite laser altimetry has a unique capability for estimating forest canopy height, which has a direct and increasingly well understood relationship to aboveground carbon storage. While the Geoscience Laser Altimeter System (GLAS) onboard the Ice, Cloud and land Elevation Satellite (ICE...
متن کاملPhotosynthetic acclimation responses of maize seedlings grown under artificial laboratory light gradients mimicking natural canopy conditions
In this study we assessed the ability of the C4 plant maize to perform long-term photosynthetic acclimation in an artificial light quality system previously used for analyzing short-term and long-term acclimation responses (LTR) in C3 plants. We aimed to test if this light system could be used as a tool for analyzing redox-regulated acclimation processes in maize seedlings. Photosynthetic param...
متن کاملContributions of Arbuscular Mycorrhizal Fungi to Growth, Biomass and Nutrient Status of Pistachio Seedlings under Saline Conditions
Excessive salt accumulation in soil is a major ecological and agronomical problem, especially in arid and semiarid areas. Excessive soil salinity affects the establishment, development and growth of plants, resulting in major losses of production. A pot experiment was set up to examine the effects of arbuscular mycorrhizal fungus (Glomus etunicatum and Glomus versiforme) and salinity on the gro...
متن کاملWoody and herbaceous competition effects on the growth of naturally regenerated loblolly and shortleaf
Four levels of vegetative competition wete used to quantify the growth of loblolly and shot-deaf pines (Pinus taeda L. and /? echinatu Mill.) in naturally regenerated, even-aged stands on the Upper Coastal Plain of southeastern Arkansas, USA. Treatments included: (I) no competition control, (2) woody competition control, (3) herbaceous competition control. and (4) total control of nonpine veget...
