摘要:

本文探究不同缩二脲含量对西瓜、辣椒、萝卜生长的影响,测定西瓜、辣椒、萝卜体内过氧化氢酶(CAT)和过氧化物酶(POD)活性以及丙二醛(MDA)含量在不同缩二脲含量下的变化,为指导西瓜、辣椒、萝卜等园艺作物的安全生产提供理论依据。结果表明,缩二脲处理会影响园艺作物的生长,尤其在高缩二脲含量下,作物的叶片出现黄化卷曲的现象;西瓜、辣椒幼苗的CAT活性随着缩二脲含量的升高呈现出先升高后降低的趋势,西瓜、辣椒和萝卜幼苗的POD活性均随着缩二脲含量的升高呈现出先升高后降低的趋势。此外,辣椒、萝卜的MDA含量也随着缩二脲含量的升高表现出不断升高的趋势。

Abstract:

This article explores the effects of different contents of biuret on the growth of watermelons, peppers, and radishes. The activities of catalase (CAT) and peroxidase (POD), as well as the content of malondialdehyde (MDA), were measured in watermelons, peppers, and radishes with different contents of biuret, providing a theoretical basis for guiding the safe production of horticultural crops such as watermelons, peppers, and radishes. The results showed that biuret treatment could affect the growth of horticultural crops, especially the leaves of horticultural crops appeared yellowing and curling under high biuret content. With the increase of biuret content, CAT activities in watermelons and peppers showed a trend of first increasing and then decreasing, and POD activities in watermelons, peppers, and radishes also showed a trend of first increasing and then decreasing. In addition, MDA content of peppers and radishes showed a trend of increasing with the increase of biuret content.

Key words: biuret, horticultural crops, growth and development, physiological index
