摘要
以宁夏枸杞种子为试材,对不同产地的宁夏枸杞种子和果实的性状指标进行测定,研究种子性状对果实生长发育的影响。结果表明:不同产地宁夏枸杞果实单粒重、果实横径、果实纵径、种子宽、种子长差异较大,而种子个数和种子重量的差异较小,种子重量与枸杞果实横径呈显著正相关,相关系数为0.486;种子长度与宽度均与果实的纵径呈现极显著正相关关系,相关系数分别为0.573和0.593。果实的单粒重与果实横径呈极显著相关关系,相关系数为0.565。说明宁夏枸杞种子的重量、种子的长度和宽度对果实的大小发育影响较大,而种子数量对枸杞果实大小发育影响不大,这可能与枸杞果实内种子个数差异不显著有关。
Taking Lycium barbarum L.as material,the effect of Lyciumbarbarum L.seed traits on fruit development,and the characteristics of Lycium barbarum L.seeds and fruits from different regions were studied.The results showed that,there was greater difference in fruit single grain weight,fruit transverse diameter,fruit longitudinal diameter,seed weight and seed length of Lycium barbarum L.in different regions,but there was litter difference in seed wide and seed number.Correlation analysis results showed that the seed weight and fruit diameter was significantly positive correlation,the correlation coefficient was 0.486;the seed length and the width and the longitudinal diameter of the fruit appear extremely significant positive correlation,correlation coefficient was 0.573,0.593,respectively.Lycium barbarum L.seed weight,seed length and width had a great impact on the fruit size development,but the impact of seed number on Lycium barbarumL.fruit size development was not great.It may related to the seed number of Lycium barbarum L.fruit was not significant difference.
