结实率 meaning in English
maturing rate
seed set propagation coefficient
Examples
- To explore the influences of setting rate of male parent varieties on that of their medium hybrid rice combinations , the correlation of setting rate between male parents and their corresponding combinations was analyzed with 7 male parent varieties and their corresponding combinations
摘要为探明父本结实率对杂交中稻组合结实率的影响，以7个父本品种和相应杂交组合为材料，对父本结实率与相应组合结实率的相关性进行了分析。 - Abstract : shuangzengji was sprayed upon indica rice shanyou 63 and wheat variety 8504 at the beginning of rice heading and full - earing stag e of wheat respectively , to study the biological effects on rice and wheat . water was used as control . the results indicated that plumpness , 1000 - grain weight and percentage of fertilized grain were increased obviously by the using of shuangz engji
文摘:以水稻品种汕优63 、小麦品种8504为材料，在水稻抽穗始期、小麦齐穗期喷施增粒增重剂(简称双增剂) ，清水做对照，研究其对稻麦的生物学效应，试验结果表明：双增剂能明显提高籽粒充实度、结实率和千粒重。 - It was found that there were changes to some extent in the main characters of the days from seeding to initial heading , plant height and seed setting rate when the seeds of the tested hybrid rice combinations and their parents were sowed at different time in hainan for the seed purity identification , and the changing extent was different between some hybrids and their parents , which would affect the accuracy of purity identification
摘要通过比较不同播种时期杂交水稻种子样品在海南种植鉴定的农艺性状表现，发现播始历期、株高、结实率等主要性状均表现出不同程度的变化，且部分组合与其亲本的变化幅度不同，从而影响鉴定的准确性。 - The results showed that : ( 1 ) a very significant increase in grain weight per plant ( gwpp ) of super high - yielding combinations mainly results from more panicles per plant ( ppp ) . ( 2 ) the order of contribution to gwpp was panicles per plant , filled grains per panicle ( fgpp ) , 1000 - grain weight ( kgw ) , spikelets per panicle ( spp ) , plumping degree ( pd ) filled grain rate ( fgr ) . ( 3 ) gwpp has positive correlation with ppp and fgpp at 0 . 01 significant level , with fgr at 0 . 05 significant level . ( 4 ) on the background of big panicle hybrid rice gwpp has positive partial correlation with ppp , kgw and pd at 0 . 01 significant level , which means any increase in these yield components can increase yield
结果表明： ( 1 )不同产量水平大穗型组合产量的差异主要受单株穗数差异的影响； ( 2 )产量构成因素对产量的作用大小依次为：单株穗数每穗实粒数千粒重每穗总粒数充实度结实率； ( 3 )单株穗数和每穗实粒数与产量正相关达极显著水平，结实率与产量正相关达显著水平： ( 4 )单株穗数、千粒重和充实度与产量的偏相关为正，且达到极显著水平，说明在大穗的基础上，单株穗数的增加、千粒重和充实度的提高可以使产量显著增加。 - The genetic correlations of six agronomic characters in some indica - japonica crosses were analyzed using mixed - linear model method . the results indicated that there existed correlations to a certain degree among the measured traits . the phenotypic correlations of plant height with filled grain or seed setting were significant . panicle length with total grains or filled grain , total grains with filled grain or seed setting , and filled grain with seed setting were the same . for panicle length with plant height or seed setting , total grains with filled , and for filled grain with seed setting , genetic correlations were also significant . further analysis , the result showed that genetic correlations between the measured traits were mainly due to domimant effects . in addition , additive correlations were significant for grain weight with panicle length or total grains or filled grain , and for total grains with filled grain
用混合线性模型方法对籼粳亚种间杂交组合农艺性状的相关性进行了遗传研究，结果表明：被测性状之间大都存在一定程度的相关.其中，株高与实粒数、结实率，穗长与总粒数、实粒数，总粒数与实粒数和结实率，以及实粒数与结实率之间具有显著的表型相关，总粒数与实粒数，实粒数与结实率，以及穗长与株高和结实率之间具有显著的遗传相关.进一步的分析表明，性状之间的遗传相关大多归因于显性效应，而粒重与穗长、总粒数和实粒数之间，以及总粒数与实粒数之间还具有极显著的加性相关
