摘要:

【目的】研究不同化学生长调节剂对打瓜生理生化指标的影响,为打瓜的生理生化特性、提高产量以及改善株型提供科学依据。【方法】以打瓜品种普通红大片的叶片为材料,利用不同种类化学调节剂,在0.005%和0.01%浓度处理下,分别在3、6、9、12和15 d测定打瓜叶片的生理生化指标。【结果】在不同浓度、种类的化学调节剂处理下,随时间增加各测定指标均呈不同程度的差异变化。0.01%化学生长调节剂处理的MDA含量在3 d时达到最大值。随化学生长调节剂处理浓度和时间的增加,可溶性蛋白含量最高能达到370.2 mg/g。氟乐灵在0.01%浓度处理下,6 d时H2O2含量达到峰值,为8.83 μmol/g;且在0.01%氟乐灵处理下,6 d时POD活性显著增加,并达到最大值,1 156.6U/g。在不同化学调节剂、不同浓度处理3~6 d处理时,SOD均有较高的活性,随后下降且变化差异不显著。在0.01%乙烯利处理下,15 d时CAT活性最低为294.7U/g。【结论】经高浓度化学调节剂处理后,打瓜的MDA含量、可溶性蛋白含量、H2O2含量以及过氧化物酶活性相较于低浓度处理显著增加。此外,随着处理时间的延长,各项测定指标均差异显著。

Abstract:

【Objective】 To study the effects of different chemical growth regulators on the physiological and biochemical indicators of the beating melon. A scientific basis for the in-depth study of the physiological and biochemical characteristics of seed melon, the enhancement of its yield as well as the improvement of plant shape. 【Methods】 The physiological and biochemical indexes of seed melon leaves were measured in 3, 6, 9, 12 and 15 d with different chemical growth regulators at 0.005% and 0.01% concentration, respectively by using the leaves of beating melon "common red large" as the test material. 【Results】 Under different concentrations and types of chemical growth regulator treatments, all the measured indexes showed different degrees of differential changes with the increase of time. The MDA content of 0.01% chemical growth regulator treatment reached the maximum value at 3 d. With the increase of chemical growth regulator treatment concentration and time, the soluble protein content could reach the maximum value of 370.2 mg/g. The H2O2 content of fluralin at 0.01% concentration reached the peak value of 8.83 μmol/g at 6 d; and the POD activity increased significantly and reached the maximum value of 1,156.6 U/g at 6 d under the 0.01% fluralin treatment. The POD activity increased significantly and reached the maximum value of 1,156.6 U/g under different chemical growth regulators and different concentration treatments. SOD had high activity at 3-6 d with different concentrations of chemical regulators, and then decreased with not significantly change. The lowest CAT activity at 15 d was 294.7 U/g under 0.01% vinlide treatment. 【Conclusion】 The MDA content, soluble protein content, H2O2 content, and peroxidase activity of beating melon were significantly increased after treatment with high concentrations of chemical regulators compared to low concentrations. In addition, with the prolongation of the treatment time, all the measured indexes show significant differences.
