冠醚对小麦、水稻某些生理特性及穗部经济性状的影响初报

EFFECTS CROWN ETHER ON SOME PHYSIOLOGICAL PROPERTIES AND ECONOMIC CHARACTERISTICS OF SPIKES OF WHEAT AND PANICLES OF RICE

以两种冠醇化合物馆和漆酚冠醚（ＳＵ１５－Ｃ－５）和苯并１５－冠－５（Ｂ１５－Ｃ－５）分别处理小麦种子和水稻秧根，研究了冠醚对两种作物某些生理特性和穗部经济性状的影响．结果表明，冠醚能促进小麦幼苗生长，提高水稻叶片中叶绿素（ａ十ｂ）含量，减小叶绿素ａ／ｂ比值，对穗部经济性状均显示出良好效果，尤其是饱和漆酚冠醚的良好生理效应更为突出．

The seeds of wheat and the young roots of rice were treated with SU15-C-5and B15-C-5. The effects of crown ether on economic characters of the spike and some physiological properties in both crops were studied. The results showed that crown ether can promote the growth of wheat seedling,improve the contents of chlorophyll(a+b) in the leavesof rice,reduce ratio of chlorophyll a to b,thus bring about good effects of economic characters of the spike. Especially, it suggests that SU15-C-5 showed better physiological effectsthan B15-C-5.
