Five early growth characters were examined in six races of Arabidopsis thaliana (L.) Heynh, their reciprocal F(1) hybrids (1974) and F(1) by tester hybrids, using a seventh race as a paternal tester. Three of the five characters were also examined at two nutrient levels in reciprocal F(1) hybrids (1972) of all seven races. Analyses of F(1) and F(1) by tester hybrids revealed significant maternal effects in all characters examined in F(1) hybrids (1972) and in root length and plant weight of F(1) (1974) and F(1) by tester hybrids. Significant reciprocal effects were found for plant weight in F(1) by tester hybrids and for seed weight, percentage of germination and root length in F(1) (1974) and F(1) by tester hybrids. The presence of significant maternal and/or reciprocal components in both F(1) (1974) and F(1) by tester diallels suggests that differences in maternal cytoplasm rather than maternal genotype per se were responsible for much of the variation resulting from these non-direct genetic effects.
五个早期生长特征在拟南芥的六个品系（L.）Heynh 及其相互 F1 杂种（1974 年）和 F1 通过测验杂种中进行了检查，使用第七个品系作为父本测验品系。在所有七个品系的相互 F1 杂种（1972 年）中，还在两个营养水平下检查了五个特征中的三个。在 1972 年的 F1 杂种中，在所有检查的特征中都发现了显著的母体效应，在 F1（1974 年）和 F1 通过测验杂种的根长和植物重量中也发现了显著的母体效应。在 F1 通过测验杂种的植物重量和 F1（1974 年）和 F1 通过测验杂种的种子重量、发芽率和根长中发现了显著的相互作用。在 F1（1974 年）和 F1 通过测验杂种中都存在显著的母体和/或相互成分，这表明来自这些非直接遗传效应的差异主要是由母细胞质而不是母体基因型本身的差异引起的。
