据有关资料报道,在某些情况下,利用化学药品处理植物,有利于远缘杂交的成功,例如应用2,4—D、2,4,5—T、蔗糖液、维生素乙等涂抹式喷射,都曾获得成效。因为喷这些药物对花粉的发芽、改变性因素间的生理过程以及减少落果等都具有一定的作用。我们从这一些资料中得到启示,1978年开始试验将维生素C应用于水稻,取得成效后,使用面积逐年扩大,1982年在本市4,569苗繁殖、制种田进行喷射,获得平均亩产增加5％左右的效果。
According to the information reported, in some cases, the use of chemical treatment of plants is conducive to the success of distant hybridization, such as the application of 2,4-D, 2,4,5-T, sucrose solution, vitamin B and other smear spray , Have achieved results. Because spraying these drugs on the germination of pollen, changing the physiological processes between factors and reduce fruit drop and so have a certain role. We got some enlightenment from these data. In 1978, we started experimenting with the application of vitamin C to rice. After its success, the area for its use has been expanded year by year. In 1982, 4,569 seedlings were bred in this Municipality and sprayed for farming. The average yield per mu was 5% About the effect.
