不同干燥方法对啤酒大麦种子发芽力的影响

Effect of different drying methods on the seed germinability in brewing barley

本试验采用人工模拟阴雨天气的方法研究二种干燥方法即睛天收获晒干和阴雨天收获35℃烘干对啤酒大麦品种浙农大 6号和浙农大 7号种子发芽力影响。试验结果表明 :2个品种均表现为 35℃烘干下种子发芽率较低 ,分别为 65 3%和 65 7% ,并且与睛天收获晒干呈显著性差异 ;与低发芽率相对应的 35℃烘干种子霉烂率较高 ,2个品种分别为 2 9 3%和 2 6 7% ;种子活力指数浙农大 6号品种也表现为 35℃烘干较低为 54 66;而浙农大 7号品种二种干燥方法对活力指数影响不明显 ;与种子活力相对应的 2个品种二种干燥方法的电导率差异均不明显 ,而α -淀粉酶活性 2个品种均以

The trial dealt with the different drying methods(sun drying and 35℃ oven drying)effecting on the seed germinability in brewing barley based on artificial simulated rain days.It was observed that the seed germination percentage at 35℃oven drying was the lowest on Zherongda No.6(65.3%) and Zherongda No.7(65.7%) and had a significant difference with the seed of sun drying.The lowest seed getmination percentage associated with the higher mould sdde percentage,Zherongda No.6(29.3%) and Zherongda No.7(26.7%).Zherongda No.6at35℃oven drying had the lower seesd vigor index(54.66),but Zherongda No.7’sseed vigor index had less influenced by drying methods.Meanwhile,the electrical conductivity during imbibon had no significant difference among 2 drying methods but the activity of α-amlyase at 35℃oven drying were lower。
