Abstract

SummaryTime-course changes of fruit cracking percentage, mechanical properties of pericarp and contents of cell wall components in litchi pericarp were studied by comparing two litchi cultivars differing in cracking susceptibility. Mechanical strength of the pericarp of crack-resistant cv. Huaizhi was greater than that of cracking-susceptible cv. Nuomici. The resistance of `Huaizhi' was also reflected in higher threshold cracking turgor as well as in higher pericarp tensile strength and extensibility. Correspondingly higher contents of calcium and structural components viz. cellulose, hemicellulose and insoluble pectin were found in the pericarp cell walls of `Huaizhi', which might have materially contributed to its higher pericarp strength and thus cracking resistance as compared with `Nuomici'.

荔枝品种果皮易裂与抗裂的比较研究

摘要通过对两个不同荔枝品种开裂敏感性的比较，研究了荔枝果实开裂率、果皮力学性能和果皮细胞壁成分含量的时间变化规律。抗裂果皮的机械强度。怀志的抗裂能力大于易裂cv。Nuomici。“怀枝”的抗裂性还表现为更高的阈值开裂膨胀，以及更高的果皮抗拉强度和拉伸性。“怀枝”果皮细胞壁中钙和结构成分纤维素、半纤维素和不溶性果胶的含量也相应较高，这可能是其果皮强度高于“糯枝”的重要原因。

期刊介绍： The Journal of Horticultural Science and Biotechnology is an international, peer-reviewed journal, which publishes original research contributions into the production, improvement and utilisation of horticultural crops. It aims to provide scientific knowledge of interest to those engaged in scientific research and the practice of horticulture. The scope of the journal includes studies on fruit and other perennial crops, vegetables and ornamentals grown in temperate or tropical regions and their use in commercial, amenity or urban horticulture. Papers, including reviews, that give new insights into plant and crop growth, yield, quality and response to the environment, are welcome, including those arising from technological innovation and developments in crop genome sequencing and other biotechnological advances.
