摘要:
[目的] 探索降低T两优164种子裂颖率和提高种子产量的方法,为其制种提供参考。[方法] 采用两因素随机区组设计,分别研究4个制种地点、6种赤霉素(GA3)用量、4种MgSO4用量对T两优164种子裂颖率和种子产量的影响。[结果] 不同制种地点和GA3用量、不同制种地点和MgSO4用量对T两优164种子裂颖率和种子产量均有极显著影响。在三亚与建宁两地制种且GA3用量为360 g·hm-2时,种子裂颖率较低,种子产量较高,其中以建宁制种点的种子产量最高。在三亚制种且MgSO4用量为1 500 g·hm-2时,种子裂颖率最低;在建宁制种且MgSO4用量为1 500 g·hm-2时,种子产量最高。[结论] T两优164最适合的制种地点、GA3用量和MgSO4用量分别为建宁、360 g·hm-2和1 500 g·hm-2
Abstract:
[Purpose] To explore the method of reducing glume cracking rate and increasing seed yield of TLiangyou 164 for seed production, and to provide a reference for seed production.[Method] TLiangyou 164 rice grown at 4 seed production fields were applied with 6 dosages of gibberellin (GA3) and 4 dosages of magnesium sulphate (MgSO4) by two-factor randomized block design. Glume cracking rate and seed yield were measured and compared.[Result] Glume cracking rate and seed yield varied significantly among different locations, and application rates of GA3 and MgSO4. In Sanya City of Hainan Province and Jianning County of Fujian Province, glume cracking rate was relatively low and the seed yield was relatively higher when GA3 was applied at 360 g·hm-2, with the highest seed yield coming from Jianning. While in Sanya, glume cracking rate was the lowest when MgSO4 was applied at 1 500 g·hm-2. In Jianning, seed yield peaked when MgSO4 was applied at 1 500g·hm-2.[Conclusion] The optimal seed production site, GA3 application rate and MgSO4 application rate for TLiangyou 164 were Jianning, 360 g·hm-2 and 1 500 g·hm-2, respectively.
