摘要
以里格尔87-5为试验材料,研究在水分调控下剪叶和灌水量对加工番茄果实生长特性的影响。结果表明,干旱胁迫下,加工番茄鲜果增重特征参数:最大增重速率时间、最大增重速率、平均增重速率、活跃生长期、增重持续天数,以及渐增期、快增期和缓增期的持续天数,表现为适水>轻度干旱>干旱,对照>剪叶,对照(30mm)>小灌量(10 mm),单果鲜重与其特征参数呈极显著正相关(P<0.01),推迟最大增重速率出现时间,延长单果增重过程持续天数、活跃生长期、快增期、缓增期和提高平均增重速率有利于单果鲜重增加。通径分析表明,单果增重持续天数和活跃生长期与单果鲜重相关性最强,呈直接的正效应,对单果增重的贡献较大,是表征加工番茄鲜果增重特征的最重要参数。总之,干旱胁迫和剪叶抑制加工番茄单果生长,降低了单果重。
Liger 87 - 5 was used as test material to study leaf-removal and irrigation on the growth of tomato fruit under water controlling. The results showed that water controlling brought different effect on tomato fruit growth parameters. The parameters of fresh fruit growth in different treatments, such as fresh fruit growth rate, period of maximum fresh fruit growth, maximum fresh fruit rate, active growth period, slow-increase period, fast-increase period, slight-increase period and the growth period, showed as Control 〉 Mild drought 〉 Drough, Control 〉 Leaf Removal, Control（30 mm） 〉 Treatment（10 mm）. There was a positive correlation between the parameters and fresh fruit weight. Fresh fruit weight had significantly positive correlation with active growth period and the growth period, suggesting that the two parameters were the main factors affecting fresh fruit weight. All results indicated that drought stress and leaf-removal inhibited tomato fruit growth and decreased fruit weight.
