Variations in leaf photosynthetic, morphological and biochemical properties with increasing plant height from seedlings to emergent trees were investigated in five dipterocarp species in a Malaysian tropical rain forest. Canopy openness increased significantly with tree height. Photosynthetic properties, such as photosynthetic capacity at light saturation, light compensation point, maximum rate...

Seagrass meadows provide a range of important ecosystem functions that can be influenced by both natural and anthropogenic pressures. One water quality for seagrass growth survival is turbidity. A study to observe impacts high turbidity morphometry was conducted in two islands i.e., Sabutung Bangko-Bangkoang Pangkep Regency. These are sediment load from several rivers Water column reducing the ...

The masked birch caterpillar, Drepana arcuata (Lepidoptera: Drepanidae) is an excellent model for studying vibratory communication and sociality in larval insects. Vibratory communication occurs throughout development, but the functions of signals are reported to change as larvae change from gregarious to solitary lifestyles. To better understand the sensory ecology of these caterpillars, it is...

Purpose: Syzygium zeylanicum (L.) DC. grows naturally in some of the Asian countries including Sri Lanka. In Belihuloya region S. trees are grown with specific characteristics than rest country and other countries. It is scientifically identified as a different variety var. lineare (Wall.). There no studies specifically focused on this tree This study has studying morphological characters suita...

abstract date palm, phoenix dactylifera, is one of the most important horticultural crops in iran. the most soils in iran, especially those cultivated with palm, are calcareous with high ph. the high ph of soil causes reduction of nutrient elements absorption. findings of researches show that application of elemental sulfur along with tiobacillus bacteria in soil, due to sulfur oxidation, reduc...

Genetic variability, correlation and path coefficients for fifteen agro-morphological traits were studied on 100 oat lines including two checks. Genotypic phenotypic of variation high leaf number per tiller weight panicle. Traits such as plant, tiller, panicle, stem width, individual plant yield, length internode thousand seed showed heritability accompanied by genetic advance indicating that t...
