Abstract
Northeast China is a key area for maize production,but the low temperatures often result in delayed maize growth and slow maturity,as well as low grain quality and high grain moisture. So,to help improve maize yield,we studied the effects of PASP-KT-NAA on maize leaf nitrogen assimilation characteristics after florescence over different accumulated temperature regions with Zhengdan 958 and Fengdan 3 maize seeds as materials,in Heilongjiang province. The protein content in maize leaves is low and the key enzyme activities of nitrogen metabolism are susceptible to changes in environment,such as frost harm,etc. For this reason,the effects of different temperatures ...
