摘要: 【目的】 研究裂果发生与内源激素、碳水化合物和细胞代谢酶活性的关系。【方法】 以易裂品种伏脆蜜为材料,采用田间试验,在裂果高发生时期的半红期,研究裂果中裂果和非裂果部位及测定正常果果皮SOD、POD、PPO、纤维素酶和果胶酶,纤维素、半纤维素、果胶物质和内源激素含量及果肉中的蔗糖、淀粉、可溶性总糖、还原性糖、葡萄糖、果糖、可滴定酸和内源激素含量。【结果】 裂果部位果皮中 POD和SOD活性极显著高于非裂果部位和正常果果皮;裂果部位果皮的半纤维素、WSP和ISP含量极显著低于非裂果部位果皮中的含量,裂果部位果皮中CSP含量显著低于非裂果部位果皮中的含量;裂果部位果肉中的可溶性总糖、蔗糖和淀粉含量显著高于非裂果部位果肉中可溶性总糖、蔗糖和淀粉含量;非裂果部位果皮中GA3含量极显著高于裂果部位果皮;在裂果部位果肉中IAA含量极显著高于非裂果果肉。【结论】 裂果部位果皮中半纤维素含量、WSP和ISP含量以及POD活性和SOD活性的变化,改变了果皮的结构和果皮的性质,再加上果肉中蔗糖和可溶性总糖含量的改变及在果皮果肉中内源激素IAA含量变化,导致果实内部和果皮不协调的生长,致使果实开裂。

Abstract: 【Objective】 To understand the relationship between endogenous hormones, carbohydrates and cell metabolic enzyme activity in fruit cracking.【Methods】 Easy to crack varieties 'fucuimi' was taken as the testing material to conduct field experiment in half red stage of dehiscent fruit high crack occurrence periods, which aimed to study dehiscent fruit and normal fruit peel SOD, POD, PPO, cellulase and pectinase, cellulose, hemicellulose, pectin substances and endogenous hormones contents, and fruit of sucrose, starch, soluble total sugar, reducing sugar, glucose, fructose, crestor titration acid and the content of endogenous hormones were determined.【Result】 The activity of POD and SOD in the peel of cracked fruit was significantly higher than that of non-cracked fruit and normal fruit.; The content of hemicellulose, WSP and ISP in the non-cracked pericarp was significantly higher than that in the cracked pericarp, and the content of CSP in the non-cracked pericarp was significantly higher than that in the cracked pericarp; The total soluble sugar, sucrose and starch contents in the pulp of the cracked fruit were significantly higher than those in the non-cracked fruit; The content of GA3 in peel of non-cracked fruit was significantly higher than that peel of cracked fruit; The content of IAA in the pulp of the cracked fruit was significantly higher than that of the non-cracked fruit.【Conclusion】 Changes of hemicellulose content WSP and ISP content as well as POD activity and SOD activity in the peel of the cracked fruit to change the structure of the peel and the properties of the peel, combined with sucrose and soluble total sugar content in the pulp of the change and the endogenous hormone IAA content in the fruit pulp, fruit growth caused by unbalanced and the changes of fruit internal osmotic potential, This causes the fruit to grow incongruously with the skin causing the fruit to crack.

Key words: jujube; fruit cracking; cell metabolic enzyme; cell wall material; sugar; endogenous hormones
