Huangguan) is a pear cultivar that rapidly developed in China. However, rapid postharvest browning appearing in fruit peel and core during storage and shelf life pose a challenge for their marketing. The potential for low temperature conditioning (LTC) treatment to inhibit peel browning and improve quality of Huangguan pears in storage and shelf life was investigated. Pears were treated at 8℃ - 9℃ for 1, 3, 6 and 9 d, respectively, physiological indexes, including peel and core browning, core breakdown, malondialdehyde (MDA) content and ethanol content were determined and quality in storage period and shelf life was evaluated in this paper. LTC treatment alleviated peel browning and core browning either in storage or shelf life remarkably;it also delayed the decline of firmness, total soluble solids and titratable acidity in storage to some extent, inhibited ethanol and MDA content both in storage and shelf life effectively and maintained juiciness and crispness of pear fruit in shelf life. These results showed that LTC can serve as an important tool for the regulation of Huangguan pears external and internal quality in storage and shelf life with economic benefits and LTC treatment for 6 d was the optimum condition in the present study.展开更多

The disorder is caused by the onset of germination associated events in the seed of developing fruit due to decreased level of very-longchain fatty acids(VLCFAs) in seed. Field trials involving preharvest application of spray formulations on developing fruits, between 50% and 60%maturity, showed that formulation V(10 g·L^(-1) NaCl, 25 g·L^(-1) CaCl_2, 0.5 g·L^(-1) KCl, 0.01 g·L^(-1) H_3 BO_3, 0.01 g·L^(-1) Cu SO_4, 0.01 g·L^(-1) Zn SO_4,0.01 g·L^(-1) FeSO_4, 0.01 g·L^(-1) MnSO_4, and 0.002 g·L^(-1) EDTA) was the most effective in preventing the jelly seed disorder. Further studies to understand the mode of action of the formulation in controlling jelly seed development, revealed increased synthesis of VLCFAs in seed followed by the rapid production of ABA and germination-inhibiting phenolic acids, besides increased accumulation of calcium in seed. These factors acting in unison delayed seed germination and decreased the activities of pectinolytic enzymes in pulp to produce healthy fruits, free from jelly seed disorder.There was an increase of mineral nutrient content in pulp of treated healthy fruits. Thus, the study helped to develop a remedy to prevent jelly seed besides revealing the biochemical mechanism by which formulation V acted to produce ‘Amrapali' mango fruits free of jelly seed with improved nutritional quality.展开更多
