【中文摘要】 香菇(Lentinula edodes)航天搭載菌株Cr-04-DZ、H_7-DZ分別與對照菌株Cr-04、H_7之間形成不明顯的拮抗線。Cr-04-DZ的氣生菌絲較Cr-04發(fā)達,而H_7-DZ菌株的情形則相反。搭載菌株25℃下菌落生長速度顯著大于對照菌株。在以蔗糖、麥芽糖和葡萄糖為碳源的培養(yǎng)基上,Cr-04-DZ菌落生長速度大于Cr-04;H_7-DZ在5種供試碳源培養(yǎng)基上菌落生長速度均顯著大于H_7。在以尿素和氯化銨為氮源的培養(yǎng)基上,H_7-DZ菌落生長速度明顯大于H_7。但在7種供試氮源培養(yǎng)基上,Cr-04-DZ與Cr-04菌落生長速度沒有顯著差異。

【英文摘要】 Strains of Lentinula edodes were boarded on recoverable balloon stayed at the height of 25km and 2()km for 4h and 1. 5h resp. . Unclear antagnistic line existed between related boarded strains (Cr-04-DZ, H7-DZ) and check strains (Cr-04, H7). Boarded strains had higher colony growth rate than that of the check strains at 25℃. With the media composed with sucrase, maltose and glucose as the carbon sources, the colony growth rate of the boarded strain Cr-04-DZ was higher than that of the check strain Cr-04. In the meantime, the colony growth rate of the boarded strain H7-DZ was remarkably higher than that of the check strain H7 on all media of five carbon sources tested. On the other hand, no significant difference existed between the colony growth rate of Cr-04-DZ and Cr-04 on all media of seven nitrogen sources tested, only the colony growth rate of H7-DZ was significantly higher than that of H7 on the media with carbamide and NH,Cl as the nitrogen sources.
