Abstract

This study aimed to investigate effect of saline water stress on growth and physiological characteristics of Calotropis procera seedling in greenhouse conditions. Experiment was performed at six Salinity levels (0, 5, 10, 15, 20 and 25 dS/m) in a completely randomized design for 5 months. Survival percentage of Milkweed seedlings at Salinity levels of 0, 5, 10 and 15 dS/m was 100, 100, 64/6 and 22/6, respectively; however, at 20 and 25 dS/m seedlings did not survive. Maximum rate of root length and volume were observed at control treatment. Maximum rates of Photosynthesis, stomatal conductance, transpiration, shoot and root dry weight, seedling height, collar diameter and number of leaves were belonged to control treatment. Maximal level of leaf temperature and root/shoot ratio were observed at Salinity 15 and 25 dS/m, respectively. Totally, findings of this study revealed that five month seedlings of Milkweed have poor viability at Salinity conditions of 15 dS/m, although at Salinity of 10 dS/m showed fairly well adaptation from the many growth and physiological characteristics, and also survival point of view.
