| 1. | Improvement of seed setting percentage of cabbage self incompatibility line by spraying fertilizers in an ex - root way
根外追肥对提高甘蓝自交不亲和系结实率的效果 |
| 2. | The hphr not only has a larger sink but also possesses normal grain - filling , sink - filling , high seed - setting percentage and heavier panicles
重穗型组合杂交稻不仅库容大，而且籽粒充实率、充实程度良好，结实率正常。 |
| 3. | 5 . the fructified rate by self - pollination is 19 . 4 % , and the rate by artificial pollination amounts to 67 . 2 % . the best time of pollintion is 24 hours after blooming
自花受粉结实率为19 . 4 % ，人工辅助授粉结实率达67 . 2 % ，最佳授粉时间在开花后24小时前后。 |
| 4. | It was also observed that the “ inter - grain apical dominance ” in hybrid rice was stronger than its restorer , which might be one of the main reasons for low seed setting in hybrid rice combination
强势粒对弱势粒物质摄取能力的优势，可能是杂交稻籽粒结实率低下的重要原因之一。 |
| 5. | The results showed that the setting rate of parent varieties has positive influences on that of combinations in general , especially for parent variety " minghui63 " , " gui99 " and " r838 "
结果表明，父本品种结实率对组合结实率普遍存在程度不同的正相关影响，尤以明恢63 ，桂99 ， r838的影响明显。 |
| 6. | In this study of the author , a cross of magnolia liliflora and magnolia " hongyuanbao " with michelia foveolata and michelia yunnanensis produced a high fruit rate of about 81 - 100 percent . these hybrids were highly vigourous
玉兰亚属的紫玉兰和红元宝二乔玉兰与含笑属的金叶含笑、云南含笑的杂交结实率高达81一100 % ，且杂交后代具有较高的活力。 |
| 7. | The primary factor to limit seed setting was the windy psychro - environment which limits the activities of insects , leading to the insect number to visited flowers decreased . all these factors induced the low setting percentage
结果表明，限制结实的主要因素是高寒多风的环境限制了昆虫的活动，访花昆虫数量减少，从而使花粉转移效率降低，导致了低的结实率。 |
| 8. | The results of the experiment showed that applying silicon fertilizer could improve the disease resistance , especially for the rice blast and changeable brown ear ; acquire high efficient tiller rate , high solid rate , big spike and could grow up at green stem
摘要试验研究表明，施用硅肥水稻抗病性明显增强，抗稻瘟病和褐变穗效果较好；施硅肥水稻有效分集率高、结实率高、穗大粗多、活秆成熟。 |
| 9. | It could be tested that parent varieties influences on the setting rate of combinations were stronger if planted or different ecological sites ; some combinations resistant to high or low temperature could be bred on purpose by taking he influences into account
利用生态点的差异，可以有效鉴定出哪些父本品种对组合的结实率影响大；利用父本品种间对组合结实率影响的差异，可以有针对性的筛选出抗高温或低温的组合。 |
| 10. | The effects of sowing dates on phenotype value of grain weight per plant , seed setting rate and path coefficients of seed setting rate were more effective than those on partial correlation coefficients between grain weight per plant and panicles per plaht , total spikelets per panicle and seed setting rate
播期对单株产量、结实率及结实率相对重要性影响较大，而对单株产量与单株有效穗、穗粒数及结实率的偏相关影响较小。 |
