摘要:

以粤晶丝苗为材料,通过大田试验,研究了超声波和种子包衣处理对水稻生理特性及产量、品质的影响。结果表明,超声波处理可以提高水稻产量,以“超声波+种子包衣”处理的产量最高,主要是由于超声波处理增加了水稻的有效穗数、每穗粒数和结实率;超声波处理可以提高水稻叶片的SOD、POD活性,增加游离脯氨酸含量,降低MDA含量,提高水稻抗性;超声波处理还可改善稻米的加工品质和外观品质。

Abstract:

A field experiment was carried out to study the effects on physilological characters, yield and quality of ultrasonic processing coated and uncoated rice seeds, taking Yuejingsimiao as materials. The results showed that ultrasonic treatment could improve the yield of rice, and the yield of ultrasonic processing coated seeds treatment was the highest, because the ultrasonic treatment increased the effective panicles, grains number per panicle and seed setting rate. What’s more, ultrasonic processing could increase SOD and POD activities and free proline contents, decrease MDA contents and improve the resistance of rice. In addition, ultrasonic treatment could also improve processing quality and appearance quality of rice.

Key words: rice, ultrasonic wave, resistance, yield, quality
