Maturity stage in harvesting time greatly affects seed vigour. This work aimed to scientific harvesting time of hybrid rice for being high vigour with high & stable seed yield. Field experiments of different harvesting time were conducted in 2013–20
1.During seed development and maturation,strong negative correlations were observed between ABA content of seed coat andseed vigor index,as well as germination rate.随着种子的成熟,种子对外源ABA的敏感性逐渐降低,种皮ABA含量与种子活力指数呈极显著负相关,与出苗率呈显著负相关,去除种皮能使萌发率和活力指数...
Rice seeds were exposed to plasma for 10, 30 and 60 s. It is shown that plasma treatment had positive effects on germination of rice seeds. Seeds exposed to plasma for 60 s had the highest germination rate. Vigor index and germination speed of treated seeds were higher in comparison to ...
According to the experiments and surveys about the female parent of hybrid rice seed production technology for direct seeding during last two years,it can be sure that the female direct seeding technology can save cost.Moreover,some recommendations about key technologies of female direct seeding,such...
In the present experiment, pollen fertility and self-fertilized seed setting rate accepted that the techniques were feasible and effective for against lower temperature and safeguarding seed production of two-line hybrid rice. 展开 关键词: two-line hybrid rice seed production purity irrigation ...
The United States Seed Market is segmented by Breeding Technology (Hybrids, Open Pollinated Varieties & Hybrid Derivatives), by Cultivation Mechanism (Open Field, Protected Cultivation) and by Crop Type (Row Crops, Vegetables). The market volume and value are presented in metric ton and USD ...
The average hole diameter is not higher than 21.7 mm, the qualified rate of hole diameter is not lower than 96.1%, and the coefficient of variation of hole spacing is not higher than 10.1%. Compared with the seed guide tube, which is increased by 32%, 16% and 34% respectively, and ...
Effect of air temperature on the seed-setting rate of hybrid rice variety II You 718; 气温对杂交水稻Ⅱ优718结实率的影响分析 2. The seed-setting rate and its relationship with source and sink by reducing source or sink were examined. 研究表明:品种间结实率差异显著,辽粳5号低于辽盐16号,辽...
