在营养条件相同的条件下,颖花数越多,库容量越大,则结实率越低,说明“库”在谷子结实中具有一定作用。同时,维管束发育好坏对谷子结实具有重要作用,表明“流”在谷子结实中的意义。改变体内营养状况,可明显地改变结实率,特別是抽穗期营养状况,茎秆含糖量与秕谷率呈显著的负相关。改变根系活性也相应地改变结实率,根系伤流量越大。秕谷率越低。说明“源”在谷子结实中具有更加重要的意义。提高谷子结实率又须适当调节库源比。
Under the same conditions of nutrition, the more the number of spikelets, the larger the storage capacity, the lower the seed setting rate, indicating that “pool” has a certain effect on the fruiting of millet. At the same time, the development of vascular bundle has an important effect on the fruiting of millet, indicating the significance of “flow” in the fruiting of millet. Changing the nutritional status in vivo could obviously change the seed setting rate, especially the nutrition status at heading stage. There was a significant negative correlation between the sugar content in stems and the rate of stolonage. Changing the root activity also changed the seed setting rate, the greater the root trauma.秕 valley rate is lower. This shows that “source” is more important in millet seed. To improve the fruiting rate of millet must be properly adjusted library source ratio.
