Fluorescence of chlorophyll pigment in leaves of soft winter wheat annual at different stages of organogenesis

Abstract

The purpose. Study of physiological state of soft winter wheat at different stages of organogenesis by determination of amount and activity of chlorophyll pigment in probed plants and response of these cultivars to conditions of overwintering. Methods. The method is used of photoinduction of fluorescence of chlorophyll pigment which enables in field conditions to determine amount of chlorophyll pigment and photosynthetic rate of 7 cultivars of soft winter wheat. Results. The essential variance in amount and activity of chlorophyll pigment between cultivars at different stages of organogenesis is determined. The opportunity of estimation of winter-hardiness by means of method of induction of fluorescence of chlorophyll pigment is shown.
