Effects of Nitrogen Application Rate on Physiological Characteristics of Flue-Cured Tobacco Leaves at the Maturing Stage
摘要
Abstract
Effects of nitrogen application rate on physiological characteristics of flue-cured tobacco leaves at the maturing stage were studied by surveying chlorophyll content , nitrate reductase(NR) activity, sol-uble protein content and free amino acid content of fresh leaves of Zhongyan 100 , a variety planted in Xuchang city of Henan Province , from different positions and in different periods every 5 days, form April to September , 2012 .The results showed that during the gradually mature process of tobacco , effects of nitrogen application rate on soluble protein content and chlorophyll content of the upper tobacco leaves were not significant , but it was significant on NR activity and free amino acids content .The effect of ni-trogen application rate on soluble protein content of the middle tobacco leaves were not significant , but it was significant on NR activity , chlorophyll content and free amino acids content .Only appropriate a-mount of nitrogen application could produce high quality tobacco leaves .The treatment of 45 kg/hm2 pure nitrogen was the best .关键词
