以青种枇杷为试材,在果实成熟前50d左右分别喷施100、200、300mg·L-1吲熟酯及0.1%钼酸铵和200mg·L-1吲熟酯+0.1%钼酸铵,研究吲熟酯和钼酸铵对果实生长发育过程中糖积累以及蔗糖与山梨醇代谢相关酶活性变化的影响。结果表明:200mg·L-1吲熟酯处理对增加果实的果糖和葡萄糖积累最为明显。所有处理的果实山梨醇含量均随果实发育呈先下降后上升的趋势。100mg·L-1吲熟酯处理的蔗糖合成酶(SS)和蔗糖磷酸合成酶(SPS)活性在5月21日后呈明显的下降趋势,其他处理的蔗糖代谢相关酶活性均呈上升趋势;山梨醇代谢相关酶活性总体上呈下降趋势。综上所述,200mg·L-1吲熟酯处理对青种枇杷果实糖积累有较显著的促进作用。
Taking loquat cultivar as tested material, 100, 200, 300 mg · L-1 indomethacin and 0.1% ammonium molybdate and 200 mg · L-1 indaculose + 0.1% ammonium molybdate The effects of indacarb and ammonium molybdate on the accumulation of sugar and the activities of enzymes related to sucrose and sorbitol metabolism during fruit growth and development were studied. The results showed that the treatment of 200 mg · L-1 indacarbyl had the most obvious accumulation of fructose and glucose. The fruit sorbitol content of all the treatments decreased firstly and then increased with the fruit development. Sucrose synthase (SS) and sucrose phosphate synthase (SPS) activity of 100 mg · L-1 indoxyl ester decreased significantly after May 21, while other enzymes related to sucrose metabolism showed an upward trend. Sorbus The activities of enzymes related to alcohol metabolism showed a general downward trend. In conclusion, 200 mg · L-1 indacrolimus significantly promoted the accumulation of sugars in loquat fruits.
