摘要
４０ｍｇ／ＬＴｉＯ２处理甜瓜幼苗３次，可减轻ｐＨ２．５酸雨对植株的伤害。作者认为，此与ＴｉＯ２能提高甜瓜幼苗光合速率、叶绿素含量，增加过氧化氢酶活性，减少丙二醛含量，降低质膜透性，维持细胞汁ｐＨ稳定性等多重生理作用相关。
Sparying muskmelon seedling three times at a concentration of 40mg/L TiO 2 reduced the damage effect of acid rain pH2.5,which might resulted from that TiO 2 raised photosnythetic rate and chlorophyll content,increased catalase activity,decreased malondialdehyde content,reduced cell membrane permeability and kept the pH stability of cell juice of muskmelon seedling.
