水分和氮素胁迫对辣椒产量形成及抗逆性评价
|
摘要
通过探索水分胁迫和氮素胁迫条件对辣椒产量及相关性状变化的影响,以期为土壤瘠薄地区辣椒水肥效应的合理应用和抗旱耐瘠型辣椒新品种选育提供依据。试验结果表明,水分和氮素之间存在互作效应,氮素具有增强抗旱性的作用,在水分和氮素胁迫下辣椒产量明显下降;H089和H089×H042025D为抗旱耐瘠型材料,花溪辣椒、H042025D和遵义朝天椒为中抗旱耐瘠型材料、DF-1和HP-1为弱抗旱耐瘠型材料。
In the paper, we studied the effects of water stress and low nitrogen stress on pepper yield and related characters, in order to provide references for reasonable use of water-fertilizer effect and breeding of new pepper cultivars with drought and poor-land resistance for Guizhou area. The results showed that, there were interactions between water and nitrogen, and nitrogen fertilizer could strengthen the effect of drought resistance, moreover, pepper yield was decreased obviously at the combined action of water and nitrogen stress. H089 and H089 ×H042025D were resistant to drought and poor land, and Huaxilajiao, H042025 D and Zunyichaotianjiao were medium resistant to drought and poor land, while DF-1 and HP-1 had weak resistance to drought and poor land.
