以洋葱种子"Wolska"为材料,研究了在10 ℃时杀真菌剂、生物制剂、PEG 8000和水引发单独处理及复合处理对洋葱种子的抑菌效果.结果表明,未处理的对照种子主要受青霉菌感染;杀真菌剂(单独处理)在很大程度上可减少青霉菌的感染率;而生物制剂(Biozym生物合剂,Promot助长剂分别单独处理)未能很好地控制青霉菌的感染;水引发剂处理后,种子青霉菌的感染率极显著地低于未处理的对照种子;在杀真菌剂与PEG 8000同时处理种子和杀真菌剂先于水引发剂处理种子的2种复合处理中,可检测到高比例的未染菌种子.
以洋蔥種子"Wolska"為材料,研究瞭在10 ℃時殺真菌劑、生物製劑、PEG 8000和水引髮單獨處理及複閤處理對洋蔥種子的抑菌效果.結果錶明,未處理的對照種子主要受青黴菌感染;殺真菌劑(單獨處理)在很大程度上可減少青黴菌的感染率;而生物製劑(Biozym生物閤劑,Promot助長劑分彆單獨處理)未能很好地控製青黴菌的感染;水引髮劑處理後,種子青黴菌的感染率極顯著地低于未處理的對照種子;在殺真菌劑與PEG 8000同時處理種子和殺真菌劑先于水引髮劑處理種子的2種複閤處理中,可檢測到高比例的未染菌種子.

Health tests were performed at 10 ℃ for untreated onion "Wolska" seeds,surface sterilized seeds,treated with fungicides and biological preparations (Biozym,Promot),osmoprimed and hydroprimed onion seeds.These tests were also carried out on seeds treated with fungicides and biological preparations in combination with osmo- and hydropriming.Untreated seeds were infested mainly with Penicillium spp.Fungicides alone reduced the incidence of Penicillium spp.on seeds to the large extent,whereas Biozym and Promot did not control these fungi.The percentage of seeds colonised by Penicillium spp.after hydropriming was significantly lower than that of untreated seeds,while after osmopriming was slightly higher.The considerable increase in inner infection by Penicillium spp.was observed after osmopriming.Among combined treatments the highest percentages of healthy seeds were observed when fungicides were applied during osmopriming or before hydropriming.
