摘　　要：以紫果西番莲‘满天星’二倍体与三倍体无菌苗为研究材料,测定不同年度生长阶段的生长和生理指标,比较其差异性,并进行相关性分析。结果表明:2种‘满天星’苗木的苗高、地径持续增长,表现出三倍体‘满天星’苗高较小、地径较大的特点。同一位置叶片的叶片长、叶片宽、叶柄长随时间变化呈先增大后减小的趋势。随时间的变化2种‘满天星’的茎节数量逐渐一致,三倍体‘满天星’苗木表现出短粗的特征。在测定期中三倍体‘满天星’可溶性蛋白和叶绿素含量大于二倍体,测量前期可溶性糖含量小于二倍体,后期大于二倍体。不同倍性的西番莲的叶绿素a、叶绿素b、类胡萝卜素与苗高、茎节、地径呈负相关,与叶长、叶柄长呈正相关;但可溶性糖、可溶性蛋白与生长指标相关性略有差异。综上所述,三倍体与二倍体的生长生理指标存在差异,且可溶性糖、可溶性蛋白与生长指标相关性存在差异。Using the diploid and triploid sterile seedlings of passion fruit'Mantianxing'as research materials,we measured the growth and physiological indexes of different annual growth stages,compared the differences between them,and carried out correlation analysis.The results showed that the seedling height and ground dia-meter of the two ploidy'Mantianxing'seedlings continued to grow,showing that the triploid'Mantianxing'seed-lings were smaller in height and larger in ground diameter.The leaf blade length,leaf blade width,and petiole length of leaves at the same position showed a trend of increasing and then decreasing with time.The number of stem nodes of the two ploidies of'Mantianxing'was gradually consistent over time,and the triploid'Mantianxing'seedlings showed the characteristic of short and thick.The soluble protein and chlorophyll contents of triploid'Passiflora'were greater than those of diploid in the measurement period,and the soluble sugar content was less than that of diploid in the early stage of measurement and greater than that of diploid in the late stage.Chloro-phyll a,chlorophyll b,and carotenoids of different ploidy of Passiflora were negatively correlated with seedling height,stem node,and ground diameter,and positively correlated with leaf length and petiole length;however,there were slight differences in the correlation of soluble sugars and soluble proteins with growth indexes.In sum-mary,there were differences in growth physiological indices between triploids and diploids,and differences in the correlation between soluble sugars and soluble proteins and growth indices.
