POROMETRIC STUDIES FOR SELECTION OF ARIDITY TOLERANT MULBERRY VARIETIES IN WESTERN RAJASTHAN

Abstract

Mulberry belongs to the family Moraceae and genus is Horus. Mulberry is a deep rooted perennial plant and leaves with acute margin, toothed, 3-5 lobed. Mulberry is primarily known as food material for silkworm and economic importance. Porometer studies growing were carried out to find out the adaptability of plants in Rajasthan. Relative temperature the experimental field in the semi-arid. The main parameters studied were: zone of leaf temperature, humidity and transpiration. It was observed was maximum (37.62°C) during summer that (noon) leaf and minimum (23.78°C) during winter (morning), relative humidity was maximum (47.26) during summer during rainy (morning) and (noon), and transpiration was minimum (13.88) maximum (10.70) rainy season (morning) and minimum (2.64) during summer (noon). The water relations studies help in identification of most adapted, aridity tolerant mulberry varieties for sericulture development in the semi-arid zone of Rajasthan.
