摘　　要：红江橙采前裂果严重。裂果率与果皮Ｃａ和盐酸溶性果胶含量负相关，与水溶性果胶正相关。分别用０．２％的ＣａＡｃ和ｃａｃｌ２两次叶面喷施于红江橙，可显著提高果皮Ｃａ的含量，减少水溶性果胶量，增加盐酸溶性果胶量，从而提高果皮破裂压力，使果皮变韧，减少裂果率。ＣａＡＣ比ＣａＣｌ２的使用效果更佳。Fruit─cracking was very serious in “Hong Jiang”sweet orange before harvest.Therewas a significant negative correlation between Ca or hydrochloric acid soluble pectin(HP)contents in peel and fruit─cracking rate.The relation between soluble water pectin(wP)and fruit─cracking rate showed a significant positive correlation. Foliar spraysof 0.2%CaAc and CaCl2 on“Hong Jiang”sweet orange resulted in a significantly in-crease of Ca of HP contents and a decrease of WP in peel, thus causing the increaseof bursting pressures in the peel, adding the resistance of fruits to cracking. The ef-fect of CaAc was better than that of CaCl2 on reduction of fruit─cracking in“HongJiang”sweet orange.
