摘要
沙棘(Hippophae rhamnoides Linn.)是我国具有重要生态意义和经济利用前景的野生植物资源,目前对其果实的经济开发研究广为注目。但是现行的剪取果枝的采果方式需要投入大量劳动力,效率很低,而且带有掠夺的性质。其结果将导致资源的严重毁灭,既影响长远的经济收益,又会造成生态环境的恶化。本研究试图通过化学处理措施对果实脱落影响的试验,为改进沙棘果实采收方式提供理论依据。
Exogenous abscisic acid can make the activity of carppodium of Hippophae rhamnoides increase immediately and causes absciss of enormous fruit. But this absciss is not concentrated and an absciss of a large number of leaves is also caused. High concentration of abscisic acid is harmful for the growth of twigs and even makes it die, and low concentration of it is available for the growth of autumn twigs. The analysis of endogenous hormone of the fruit that trops naturally shows that with the development of absciss the abcisic acid and the class of kinin increase obviously, and also there is a little increase of somatotropin. This result tallies with what the absciss of fruit treated by exogenous hormone.
