According to the research of physiological and biochemical indicators or index, components of soluble proteins, substrate protein of phosphorylation and the activity of protein kinase in low - temperature stress in the leaves of brassica oleracea l., we tried to find the law of the physiological and biochemical response of brassica oleracea l. leaf to low temperature. at the same time, discussion on the signal transduction can also provide further evidences for revealing the mechanism of low - temperature stress. the results are showed as follows : malondialdehyde ( mda ), superoxide dismutase ( sod ), ascorbate peroxidase ( asp ) and peroxidase ( pod ) activities were changed greatly after 0 ~ 30min ' s treating with low temperature
本文以甘藍葉片為材料，通過對低溫5脅迫下甘藍生理生化指標、可溶性蛋白組分以及磷酸化底物蛋白、蛋白激酶活性的研究，以期找出甘藍葉片對低溫脅迫的生理生化響應規律，為甘藍露地越冬栽培防範寒害提供理論指導，同時對低溫脅迫下甘藍逆境信號傳導進行了探討，從而為徹底弄清低溫脅迫機理提供進一步的證據，研究的主要結果如下：丙二醛含量（ mda ） 、超氧化物歧化酶（ sod ） 、抗壞血酸過氧化物酶（ asp ）和過氧化物酶（ pod ）活性在低溫處理0 30min發生顯著變化，低溫處理3min后，甘藍葉片內mda含量基本沒有變化，處理5min時出現第一個峰值，達到對照的104 . 10 ， 10min出現低谷，僅為對照的86 . 27 ，隨后再次上升， 30min時超過第一峰值，為對照的113 . 93 。 -
This review focuses on morphological and physiological reactions of fruit tree to water stress. leaf area, root growth and microstructure of leaves and roots were investigated. some physiological and biochemical index of fruit tree leaves and roots under water stress, such as variations of stomatal aperture, photosynthesis, photoinhibition, metabolism of lipoxygenase, content of proline, nuclear acid and endogenous phytohormones, were summarized
從水分脅迫對果樹葉、根的形態指標及顯微結構，葉片氣孔行為、光合作用、光抑制、活性氧代謝、脂氧合酶代謝、多胺代謝、脯氨酸、核酸代謝、內源激素變化等生理生化方面綜述了近十幾年來的研究成果，為全面研究果樹抗旱機理及進一步制定抗旱措施奠定理論基礎。
