DIURNAL COURSE OF CERTAIN LEAF MOISTURE CHARACTERS IN IRRIGATED AND UNIRRIGATED BLACK GRAM

Abstract

The effect of irrigation on diurnal changes of certain leaf moisture characteristics was studied during early bean filling in black gram. There was a reduction in leaf water potential and transpiration, while there was an increase in leaf temperature and stomatal resistance as the day advanced from 8 to 14 h. Irrigation had favourable influence on the leaf moisture characters while non- irrigation proved deleterious. Mid-day observations of the leaf moisture parameters are advisable in the screening of black gram cultivars for drought.
