摘要
以辣椒核质互作雄性不育系9704A,8214A和它们相应的保持系9704B,8214B为材料,研究了叶片和不同发育阶段花蕾的总呼吸速率(Vt)、抗氰呼吸速率(Valt)和抗氰呼吸速率所占总呼吸速率的比例(Valt/Vt)的变化趋势。结果表明:在不育系中,随着花蕾的发育,总呼吸速率(Vt)、抗氰呼吸速率(Valt)和抗氰呼吸速率所占总呼吸速率的比例(Valt/Vt)呈下降趋势;而在保持系中总呼吸速率(Vt)变化趋势不明显,抗氰呼吸速率(Valt)和抗氰呼吸速率所占总呼吸速率的比例(Valt/Vt)呈上升趋势;在叶片中,不育系的总呼吸速率(Vt)、抗氰呼吸速率(Valt)和抗氰呼吸速率所占总呼吸速率的比例(Valt/Vt)均小于保持系。
Capsicum annuum L. cytoplasmic male-sterile lines （CMS） 9704A and 8214A and their maintainer lines （M） 9704B and 8214B were used as the experimental materials. An investigation was made on tendency of mean total respiration rates （ Vt）, cyanide-resistant respiration rates （Vah） and ratio of Valt to Vt （Vah/Vt） of the leaves at the stage of full bloom and the flower buds at different flower stages from 9704A, 8214A, 9704B and 8214B. The results showed that Vt, Valt and Valt/Vt in the CMS were slightly decreased, whereas Vt in the M reflected an ambiguous tendency, Valt and Valt/Vt in the M reflected an increasing tendency during flower buds developing. Vt, Vah and Vah/ Vt in the leaves of CMS were higher than those of M in he leaves in the stage of full bloom.
