PDJ

So as to improve grains yield. Of all teatments, 10mg/ kg PDJ spraying treatment with 16. 7% increase of the yield per stem is significance;

促进干物质的累积，从而提高了谷粒产量其中10mg／kgPDJ喷雾处理，提高了单株产量16.7%，差异显著；

The results showed that vacuole of treated cell with PDJ ( Propyl dihydrojasmonate) was larger than that of control, membrane bright band disappeared, electron density and permeate of plasmalemma increased after PDJ treatment in epidermic cell.

结果显示，PDJ处理后根尖表皮细胞的液泡增大，细胞体积也增大，细胞膜的亮带消失，电子密度增大，细胞膜相对透性增加；

The results indicated PDJ could improve the vigor of root system and NRA of leaves, increase chlorophyll and soluble protein content, thus laying a better physiological foundation for high yield.

结果表明，二氢茉莉酸丙酯提高了根系活力和叶片硝酸还原酶活性（NRA），增加叶绿素含量和可溶性蛋白含量，从而为高产奠定了良好的生理基础。

05mg/ kg PDJ root soaking with 20. 8% increase is very significance.

05mg/kgPDJ浸根处理，提高了单株产量20.8%，差异极显著。

Principal component analysis shows that the comprehensive effect was the best with PDJ treatment, and high concentration PDJ has better effect than low concentration PDJ, while the rooting powder treatment was less effective than the control treatment.

运用主成分分析的方法可得出PDJ处理的综合效果最好，其中高浓度PDJ处理效果较低浓度好，而生根粉的综合效果不及对照处理。
