15 صفحه اولEffect of Salinity on Germination, Growth, Yield, Ionic Balance and Solute Composition of Pigeon Pea (cajanus Cajan (l.) Millsp)
Salt tolerance of Pigeon pea (Cajanus cajan (L.) Millsp) was determined at three growth stages since it has already been observed by a number of workers that degree of salt tolerance of different crops varies with their ontogeny. Therefore, salt tolerance of three accessions, Local Arhar, ICPL-151 and ICPL-850014 of pigeon pea was assessed at germination, seedling and adult stage. It is clearly...

1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
