摘要:

本文以蒲公英地上和地下部分为试材,研究其不同浓度的水浸液对辣椒幼苗生长以及相关生理指标的影响。结果表明:辣椒幼苗生长的形态指标和叶片光合特性与水浸液浓度间存在正相关关系,A0.06、B0.04处理的PN、EVAP和GS有所下降但下降幅度不大。幼苗POD活性、MDA含量随水浸液浓度的增加而增加,而膜脂过氧化作用降低。地上和地下部分的水浸液对其影响趋势一致。

The above- and below-ground parts of Taraxacum mongolicum were taken as experimental materials. The effects of its aqueous extracts with different concentration on seed germination and seedling growth of hot pepper were investigated. The results showed that the morphological and photosynthetic characteristics of hot pepper seedlings growth were significantly positive with the aqueous extracts concentration. The PN, EVAP and GS values of A0.06, B0.04 treatment were not significant decrease. POD activity and MDA content were increased with the increasing concentration, and the MDA content was decreased. The membrane lipid peroxidation is also reduced. The effect trends of aqueous extracts of above- and below-ground parts were consistent.
