1.提高陈种的发芽率。杂交稻隔年存种,不论贮藏好坏,其发芽率均有不同程度下降,利用微量激素对隔年存种进行适度的处理,能大大提高其发芽率。 (1)九二○对隔一年陈种与隔两年陈种的处理有不同程度的作用,而均以30ppm的浓度最佳。对隔一年陈种可以提高发芽率5.3%;对隔两年陈种可以提高发芽率48.7%。 (2)ANN对隔一年陈种以20ppm处理最好,提高
1. To improve the germination of Chen species. Seed germination of hybrid rice in the next year, regardless of storage quality, the germination rate has decreased to varying degrees, the use of trace hormones on the next year, the proper treatment of species, can greatly improve its germination rate. (1) Nine two two pairs of Chen species every year and two years of Chen species treatment to varying degrees, and both 30ppm concentration of the best. For every other year, Chen seeds can increase the germination rate by 5.3%; for the other two years, the germination rate can increase by 48.7%. (2) ANN on the best species to improve 20ppm treatment every other year
