narrow heritability meaning in English

狭义遗传率

The narrow heritability of the growth period and the period from sowing to budding were higher , separately reaching 66 . 1 % and 49 . 1 % , and interacted weakly , while the positions f the first fruiting shoots and the period from sowing to budding had the lowest narrow heritability , separately equal to 19 . 8 % and 18 . 8 % , and their interactions with the environments reached a significant level ; the heritability of the periods from budding to flowering and flowering to boll opening , and the stem heights , as well as their interactions with environments took the second place
生育期、播种开花的狭义遗传率均较高，分别为66 . 1 %和49 . 1 % ，且与环境互作效应较小，而果枝始节和播种现蕾的遗传率最低，分别为19 . 8 %和18 . 8 % ，且与环境互作达到极显著水平，现蕾开花、开花吐絮和株高这3个性状的遗传率及其与环境互作居中。
