硝酸钙和IAA对温州蜜柑果实钙含量及其品质的影响
Effects of calcium nitrate and IAA on calcium concentration and quality of satsuma mandarin fruit
摘要
Abstract
Experiment was carried out with the fruit of Kamei satsuma mandarin cultivar. Calcium nitrate [Ca(NO3)2], IAA,and IAA + Ca (NO3)2 were sprayed at the stages of full bloom, 1 week and 3 weeks after full bloom, and 2 weeks before harvest. The calcium concentrations in the whole fruit, rind and pulp in different phases were investigated, and their fruit quality was analyzed in comparison with fruit infiltrated with Ca(NO3)2 after harvest and fruit of full ripe harvest. The results showed: 1) Ca concentrations in the rind of all spray treatments increased at 51 days after full bloom (DAFB) and 112 DAFB,whereas Ca concentrations in the whole fruit were not significantly different among sprays and control. At usual harvest, Ca concentrations in the whole fruit and pulp of all sprays were significantly higher than those of control. 2) Soluble solids content (SSC) and titratable acidity (TA) of spray treatments were all statistically lower than those of control, while soluble sugar (SS) concentration, mean single fruit weight, rind color parameters and relative inductivity of sprays did not differ significantly among sprays and control, SS/TA of all spray treatments were significantly higher than that of control. 3) At 30 days after usual harvest, Vc of IAA + Ca (NO3)2 spray and postharvest Ca infiltration treatments, and SSC and SS of full ripe fruit were all significantly higher than those of control and other treatments.关键词
