摘　　要：研究光强对砀山酥梨果实发育过程中石细胞形成的影响，探讨了内源激素和梨石细胞形成的关系。结果表明：梨花后第1周～11周是石细胞形成期，石细胞含量为高光强〈中光强〈弱光强〈极弱光强；内源IAA、ZR含量于花后第1周与第7周分别出现2次高峰；花后第1周内源ABA含量最高后迅速下降，IAA、ZR和ABA含量为高光强〉中光强〉弱光强〉极弱光强。高光强促进砀山酥梨果实发育前期IAA、ZR和ABA合成．减少石细胞的积累。The effect of light intensity on the stone cell in Pyrus, spp during fruit growth and development and relation of the endogenous hormone and the stone cell growing were studied. The result indicated： Time of stone cell formation is from the first week to the eleventh week after flowering. The stone cell content in different light intensity is different. Its content in thinnest light is the highest, the thin light intensity is higher, the middle light intensity is followed, and the high light intensity is the lowest. Endogenous ZR and IAA content have two peaks during fruit growth and development of Pyrus. spp. The highest content of ZR and IAA appears at the first week after blooming, and another peak of ZR and IAA appears at the seventh week after blooming. The highest content of ABA appears at the first week after blooming, and it decreases gradually. Endogenous hormone content in high light intensity is the highest, the middle light intensity is high- er, the thin light intensity is followed, and the thinnest light intensity is the lowest, which showed light intensity is favor to promote endogenous hormone synthesis, to reduce the stone cell formation in Pyrus. spp.
