研究了洋葱种子“Wolska”在PEG8000和水引发条件下的萌发情况,以及杀菌剂(Penncozeb硫锌制剂和Apron爱普荣)和生物制剂(Biozym生物合剂,Promot助长剂)对洋葱种子萌发的影响。结果表明,10℃PEG引发处理中,所有的达到最大萌发率的时间和平均萌发时间较对照极显著减小,在该温度下,水引发处理效果比PEG引发好;20℃时,水引发处理达到最大萌发率的时间和平均萌发时间与对照及PEG处理间没有显著差异。杀菌剂处理在10℃时延缓了萌发速度,而在20℃时所有处理达到最大萌发率的时间和平均萌发时间与对照无显著差异。生物制剂处理在10℃和20℃下对萌发速度均没有改善;与对照相比,10℃的PEG引发与水引发处理极大地改善了萌发力;20℃时的生物制剂处理、PEG引发和水引发处理与对照相比,均未显著改善萌发力。
The germination of onion seed “Wolska” under PEG8000 and water-induced conditions was studied, as well as the germination of onion seeds by using bactericide (Penncozeb Zinc and Apron) and biological agents (Biozym biological agent, Promoter) Impact. The results showed that all the time to reach the maximum germination rate and the average germination time in PEG-induced treatment at 10 ℃ were significantly decreased compared with the control, and the water-induced treatment effect was better than that of PEG at 20 ℃. The water-induced treatment The time to reach the maximum germination rate and the average germination time were not significantly different from the control and PEG treatments. Bactericide treatment slowed the germination rate at 10 ° C, whereas at 20 ° C there was no significant difference from the control for the maximum germination rate and mean germination time for all treatments. The biologics treatment did not improve the germination rate at both 10 ° C and 20 ° C; PEG priming and water priming at 10 ° C significantly improved germination compared to controls; biologics at 20 ° C, PEG priming and water No significant improvement in germination was found in both priming and control treatments.
