不同细胞质对小麦花药游离氨基酸含量影响的初步研究 A PRELIMINARY STUDY ON THE EFFECT OF DIFFERENT CYTOPLASM ON THE AMOUNT OF FREE AMINO ACIDS IN ANTHERS OF WHEAT 徐乃瑜 1 2 first-author 范濂 1 2 张清海 1 2 武汉大学生物系 武汉大学生物系 河南农学院农学系 河南农学院农学系 不育系花药游离氨基酸的总含量和多数氨基酸的含量,都高于同核保持系。其中差异最显著的是天门冬酰胺和脯氨酸,前者不育系远比保持系高,后者则反之。不同类型不育系间各种氨基酸含量和总含量也存在有明显差异。恢复系各种游离氨基酸含量与保持系比较相似。不育系杂种随着育性的恢复,其脯氨酸含量迅速提高,天门冬酰胺和氨的含量迅速下降,趋向于正常可育系的含量。 The total amount of free amino acids and the each amount of most amino acids contained in anthers of the sterile lines were higher than their maintai-ner. Among which the differences in asparagine and proline content were most prominent, in asparagine the contents of sterile line were noptably higher than its maintainer, but in proline it was conversely. Among the different types of male sterile lines, the differences of each amino acid content and the total amount were very prominent. The amount of different free amino acids in restorer was comparatively similar to that of the maintainer. The recovery of fertility in sterile hybrid was accompanied by rapid increase in their proline content and prompt de-crease in asparagine and ammonia contents, tending to that of normal fertile line. 1984-02-01 2021-04-01 2
