摘要: 以青脆李(Prunus salicina Lindl.)为材料,通过跟踪检测青脆李K、P、Ca、果胶和纤维素的变化规律,观测果肉、果皮与裂痕处细胞生长速率,研究了青脆李裂果的相关机理。结果表明,在K、P、Ca 3种元素中,Ca对青脆李裂果的影响最大,K次之,P与裂果无明显相关性。果胶与纤维素含量都与青脆李裂果有明显相关性。解剖结构研究表明,青脆李裂果的直接原因是成熟期表皮细胞、薄壁组织细胞和果肉细胞的生长不协调。

关键词: 青脆李(Prunus salicina Lindl.), 裂果, 矿质元素, 果胶和纤维素, 细胞生长速率

Abstract: By detecting the changes law of K, P, Ca, pectin and cellulose in plum(Prunus salicina Lindl.) continuously, and observing the growth rate of pulp cells, skin cells and the cells nearby rifts, the Qingcui plum was used as material to study the mechanism of fruit cracking. The results showed that the Ca had the greatest effect on fruit cracking among three elements, K ranked second place, and P had no obvious effect. The cellulose and pectin had obvious relevance to dehiscent fruit. The anatomical observations and micro-measurements showed that, uncoordinatedly growing of epidermal cell, parenchyma cells and pulp cells caused fruit cracking.

Key words: Prunus salicina Lindl., fruit cracking, mineral element, pectin and cellulose, growing rate of cell
