摘要：

探讨盐渍地条件下不同品种甘薯产量和内源激素含量差异，旨在筛选出盐渍地种植的适宜品种及耐盐新品种选育的亲本材料。以20个福建省本地选育的甘薯品种（系）为试材，在盐渍地开展适应性种植试验，种植60 d后测定甘薯叶片和块根的内源激素含量，140 d后收获测定块根产量。结果表明：（1）盐渍地种植甘薯块根产量达30000 kg/hm2以上的品种（系）有：‘龙薯10号’、‘福薯604’、‘R132’、‘R106’、‘金山57’、‘金薯20’、‘龙薯116’、‘福宁紫5号’，属于盐渍地高产类型，块根产量比对照下降幅度低于10%，耐盐指数高于1.1，属于强耐盐品种（系）。（2）相关性分析表明，盐渍地种植不同品种（系）甘薯块根产量与叶片IAA、GA3、ZR含量呈显著正相关，与叶片ABA含量呈显著负相关；与块根IAA、GA3、ZR含量呈极显著正相关，与块根ABA含量呈极显著负相关。综上，‘龙薯10号’、‘福薯604’、‘R132’、‘R106’、‘金山57’、‘金薯20’、‘龙薯116’、‘福宁紫5号’等品种（系）适宜用于盐渍地种植及耐盐甘薯新品种选育的亲本材料。

Abstract:

The study aimed to explore the differences of yield and endogenous hormone content of different sweet potato varieties under salinized soil conditions, in order to screen suitable varieties for planting in salinized soil and parent materials for breeding new salt tolerant varieties. 20 locally selected sweet potato varieties (lines) in Fujian Province were used as materials for adaptive planting experiments in salinized soil. After 60 days of planting, the endogenous hormone contents of sweet potato leaves and tubers were measured, and the tuber yield was measured after 140 days. The results showed that: (1) the varieties (lines) with sweet potato tuber yield of more than 30000 kg/hm2 in salinized soil included ‘Longshu 10’, ‘Fushu 604’, ‘R132’, ‘R106’, ‘Jinshan 57’, ‘Jinshu 20’, ‘Longshu 116’ and ‘funingzi 5’, which belonged to the high-yield type in salinized soil. The tuber yield decreased by less than 10% compared with the control, and the salt tolerance index was higher than 1.1, belonging to strong salt tolerant varieties (lines). (2) Correlation analysis showed that the tuber yield of different sweet potato varieties (lines) planted in salinized soil was significantly positively correlated with IAA, GA3 and ZR contents in leaves, and significantly negatively correlated with ABA content in leaves. It was extremely significantly positively correlated with IAA, GA3 and ZR content in tubers, and extremely significantly negatively correlated with ABA content in tubers. In conclusion, sweet potato varieties(lines) such as ‘Longshu 10’, ‘Fushu 604’, ‘R132’, ‘R106’, ‘Jinshan 57’, ‘Jinshu 20’, ‘Longshu 116’, and ‘Funingzi 5’ are suitable for planting in salinized soil and be used as parent materials for breeding new salt tolerant sweet potato varieties.
