摘要
对杂交棉杂29一代、杂29二代及其亲本86—56系((?))、711—22((?))的净光合速率、气孔导度、蒸腾速率、超氧化物歧化酶活性、过氧化物酶活性和丙二醛含量进行了研究。结果表明,杂29一代、二代的净光合速率和蒸腾速率具有超亲优势,气孔导度在杂29一代为超亲优势,在杂29二代为中亲正优势。在杂29一代,超氧化物歧化酶活性为超亲优势,过氧化物酶活性为中亲正优势,丙二醛含量为中亲负优势。
The net photosynthetic rate (NPR), stomatal conductance (SC, transpiration rate (TR), SOD activity, POD activity and MDA content were studied for cotton hybrid Za29 F1 and F2. The results showed that there were positive super-parent heterosis for NPR and TR of F1 and F2, and for SC and SOD activity of F1, and positive mid-parent heterosis for SC of F2 and POD activity of F1, but negative mid-parent heterosis for MDA content of F1.
