摘　　要：研究了钛对小麦旗叶某些光合功能和穗部性状的影响。结果表明,钛能提高小麦旗叶的叶绿素和类胡萝卜素含量、PSⅡ活性、PSⅡ原初光能转化效率以及潜在光合作用量子转化效率;加速小麦的灌浆进程,促进穗粒数和千粒重的增加,有利于提高小麦产量。由于钛能改善植物的光合功能和作物产量的构成因素,因此,钛制剂在农业生产上将有良好的应用前景。The effects of titanium on some photosynthetic functions of the flag leaves and characteristics of wheat spike were studied in this paper. The experimental results showed that the contents of chlorophyll and carotenoid in unit fresh weight or in unit leaf area, PS II activity, the efficiency of primary conversion of light energy of PS II and the efficiency of potential photosynthetic quantum conversion of a leaf from wheat flag leaves were raised by titanium. At the same time, titanium was advantageous to the accelerate of wheat milk course and the increase of per spike grain and one-thousand grain weight. Owing to titanium being able to improve plant photosynthetic. functions and component factors of crop yield, it will have fine prospeets for practical application to argricultural production.
