图2 人工老化前后种子萌发表型和发芽统计 A: 老化处理和未老化处理的杂交种及父母本种子的萌发表型。B: 人工老化处理对杂交种及父母本的发芽率、根长、芽长的影响。发芽率在(P<0.01)时差异极显著, 用**表示; 根长在(P < 0.05)时差异显著, 用*表示; 芽长差异不显著。0~5 d: 老化处理的天数。

Fig. 2 Seed germination phenotype and germination statistics before and after artificial aging A: germination phenotypes of artificially aged and untreated seeds of hybrid and parents. B: effects of artificial aging on germination rate, root length and shoot length of hybrids and parents. ** and * indicate significant differences at the 0.01 and 0.05 probability levels, respectively. 0-5 d: Day(s) of aging treatment.
