CCC浸种对小麦生长性状的影响

THE EFFECTS OF GROWTH CHARACTER THROUGH SEED SOAKING IN CCC SOLUTION ON DRYLAND WINTER WHEAT

ＣＣＣ浸种的效应与其浓度密切相关。１０％的浓度明显降低出苗率；浓度低于５％对出苗率无影响。在０．１％一１０％之间，随浓度增高，茎叶干重降低，而根系干重增加。增加根系总长度的效果以０．１％一３％的浓度最好。浓度在５％范围内，叶绿素含量随浸种浓度的升高而增加．浓度高于１％时叶面积减小。全面权衡，旱地小麦ＣＣＣ浸种最适宜的浓度为１％。

There is a significant correlation between the effects of seed soaking in the CCC solution andits concentration. The CCC solution has no influence upon the emergence rate of seedling while itsconcentration is below 5%,but it makes the emergence rate become lower when the concentrationis 10%。 Between 0.1%一10%,the dry weight of its stem and leaf descends with the concentra-tion increase,but the dry weight of its root increases. The best effect of increasing total root lent-gth is 0.1%一3%of Concentration; The leaf area is lower when the CCC concentration is above1%。 Blow 5%of concentration,the content of chlorophyll increases by increasing the concentra-tion, To make an all一round weight , the suitable concentration for wheat seed soaking is 1%inthe arid area.
