Improvement of water use efficiency in young mangosteen plants

Mangosteen seedlings were subjected to soil drying by allowing the seedling to dry out the soil over 10 days. The experiment was conducted in four replications to investigate the role of foliar spray of ABA on leaf gas exchange and survival of young mangosteen seedlings. Leaf gas exchange parameters and water relations were declined with the onset of water deficit. Foliar application of ABA enhanced the water use efficiency and survival of young mangosteen plants under limiting water conditions by inducing earlier stomatal closure.

Abstract

Mangosteen seedlings were subjected to soil drying by allowing the seedling to dry out the soil over 10 days. The experiment was conducted in four replications to investigate the role of foliar spray of ABA on leaf gas exchange and survival of young mangosteen seedlings. Leaf gas exchange parameters and water relations were declined with the onset of water deficit. Foliar application of ABA enhanced the water use efficiency and survival of young mangosteen plants under limiting water conditions by inducing earlier stomatal closure.
