THE EFFECT OF CONDITIONS ON THE WATER RETENTION PROPERTIES OF BEAN VARIETIES GROWN IN THE CONDITIONS OF SAMARKAND REGION

In this article, the ability of leaves of bean varieties to retain water under normal and arid conditions of typical gray soils in the Pastdargom region of the Samarkand region is studied and also the characteristics of drought resistance of these varieties are analyzed. The research is described on the analysis of the physiological and biochimcal bases of adaptation in the selection of drought-resistant bean varietiesin the Samarkand region, as well as the selection and production of valuable highyielding varieties suitable for this region.

Keywords: Samarkand region, bean varieties, water-holding capacity, legmunious crops, physiological characteristics.
