Investigating the effect of growth regulator, furolan on starch and protein contents in winter wheat cultivars

Abstract

This study was carried out to investigate the effect of growth regulator, Furolan on the starch and proteins components of three varieties of winter wheat grains namely Bat’ko, Deya and Krasnodarskaya 99. The carbohydrate complex and general protein contents in the winter wheat were determined by standard methods of analysis. From the results obtained in the study, winter wheat grain of Bat’ko and Deya varieties contained more protein than Krasnodarskaya 99 variety, which meant the early-ripening variety of Bat’ko had less starch than the late-ripening varieties of Deya and Krasnodarskaya 99. Thus, protein accumulation prevailed over starch in the grains of the early-ripening varieties while in the late-ripening varieties the reverse was the case. This could be linked to the. observation made in the study that Furolan promoted more active accumulation of starch in Krasnodarskaya 99 (0.6 and 1.2 ± control for 2004 and 2005 respectively) and Deya (2.8 and 2.2 ± control 2004 and 2005 respectively) varieties while it increased the protein content in Bat’ko variety (2.4 and 1.2 ± control for 2004 and 2005 respectively) by enhancing the expressivity of its genetic system of attraction and net photosynthetic productivity.
