利用稻曲球浸提的稻曲菌素液对不同抗性水平水稻种子进行处理,研究稻曲菌素与水稻品种抗稻曲病之间的相关性。结果表明:稻曲菌素对水稻种子的萌发、胚根及胚芽的生长都有抑制作用,对胚根数的抑制作用较强;同时,稻曲菌素处理种子,可抑制抗病品种的种子萌发,但能促进感病品种的种子萌发。这说明稻曲菌素对水稻种子发芽的抑制水平与品种抗性之间有一定相关性。
The rice seeds of different resistance levels were treated with rice curculigin extract, and the correlation between rice melitensin and rice varieties resistant to rice false smut was studied. The results showed that rice could inhibit the germination of rice seeds, the growth of radicle and germ, and had a strong inhibitory effect on the number of radicles. At the same time, Germination, but can promote the seed germination of susceptible varieties. This indicates that there is a certain correlation between the inhibitory effect of rice asparticum on the germination of rice seeds and the resistance of cultivars.
