栀子种子生活力的测定及其与发芽率的相关性研究

    Study on effect of different loading tobacco leaf methods on curing in bulk curing barn

    • 摘要: 以5 个不同产地的栀子作为试验材料,分别用TTC 染色法、BTB 指示剂、红墨水染色法测定种子的生活力。测定不同培养床(蛭石、纱布、滤纸、沙子)和不同温度(30、25、20、15益恒温和30/20、25/15益变温)对发芽率的影响,优化萌发条件。探讨测定栀子种子生活力的最佳方法,明确其生活力与发芽率之间的相关性。结果显示院BTB 指示剂法是测定栀子种子生活力的最佳方法,在滤纸培养床、30益恒温培养条件下,栀子的发芽率最高。BTB 指示剂法测定的栀子种子生活力和发芽率的相关系数为0.979,存在显著的正相关性,进一步得到栀子种子生活力(X)与发芽率(Y)的回归方程为Y=1.219X-0.199。

       

      Abstract: In order to explore suitable loading tobacco leaf methods for Guangdong爷s tobacco production, we compared the effectof three different methods (loading leaf with clip, loose-leaf with skewer and traditional loading leaf with pole). The results showed that compared with the traditional way, equipment investment cost of the loading leaf with clip and loose-leaf with skewer was higher, but tobacco leaf amount and loading density of the two methods increased dramatically, loading and unloading efficiency was improved greatly, labor costs significantly declined. And this two methods reduced the curing's energy consumption, which would have shown additional saving curing cost. In addition, seen from economic character, the effectofloading leaf with clip was the best, loose-leaf with skewer and traditional loading leaf with pole were followed, therefore we found that loading leaf with clip method was worth further experiment and popularizing in Guangdong.
