摘要
为解决续随子在贵州喀斯特山区大面积种植中面临的干旱问题,研究了不同干旱胁迫对续随子生育特性的影响。结果表明:不同干旱胁迫对续随子植株生长发育和开花结果有显著影响;随着干旱胁迫程度的加重,续随子株高、杆高、分枝数、单株蒴果数、地径和叶面积均呈逐渐下降趋势。通径分析表明,单株蒴果数对单株产量的直接作用最大;地径与株高、杆高、叶面积、分枝数、单株蒴果数存在协同作用,叶面积与其他性状不存在协同作用。
The results from studying the effect of different drought stress on fertility characteristics of Euphorbia lathyris showed that different drought stress had significant effect on growth development,flowering and bearing of Euphorbia lathyris,plant height,stem height,number of branches,number of capsules per plant,ground diameter and leaf area reduced with the increase of drought intensity.The path analysis showed that number of capsules per plant had the maximum direct effect on yield per plant,ground diameter and plant height,stem height,leaf area,number of branches,number of capsules per plant had the synergistic effect on yield per plant,leaf area and other characters had no synergistic effect on yield per plant.
