Abstract

Tomato (C3-plants) and maize (C4-plants) were grown in a nutrient solution to which triacontanol was added twice a week. After about 4 weeks the triacontanol treatment caused a significant increase in the dry weight of the tomato plants. Leaf area and dry weight measurements of tomato leaves at different stages of development showed that the largest increase in growth was obtained when triacontanol treatment was initiated before bud formation. In maize, no effect of the triacontanol treatment on dry wieght was observed. Photosynthesis was inhibited by 27% in young leaves from triacontanol-treated tomato plants and 39% in the controls, when the oxygen concentration was raised from 2% to 21%. In maize no change in photosynthesis could be observed, neither after altered oxygen concentration nor after triacontanol treatment. The difference in the response of C3- and C4-plants to triacontanol indicates that it regulates processes related to photosynthesis.

摘要

番茄（C3 植物）和玉米（C4 植物）在营养溶液中生长，每周两次添加三十烷醇。大约 4 周后，三十烷醇处理导致番茄植株的干重显著增加。对不同发育阶段的番茄叶片的叶面积和干重测量表明，在芽形成前开始三十烷醇处理时，生长的最大增加。在玉米中，未观察到三十烷醇处理对干重的影响。当氧浓度从 2%升高到 21%时，来自三十烷醇处理的番茄植株的幼叶的光合作用被抑制了 27%，而对照中的光合作用被抑制了 39%。在玉米中，无论是改变氧浓度还是三十烷醇处理后，都不能观察到光合作用的变化。C3-和 C4-植物对三十烷醇的反应差异表明，它调节与光合作用有关的过程。
