- 摘要:
- 以5 a生“西林3号”、“西扶1号”、“香玲”和“强特勒”4个核桃品种的成熟果实为试材,研究比较了其青果和坚果外观性状等指标。结果表明：“西林3号”核桃青果各项测定指标明显大于其它3个品种，且与其它品种相同指标的差异均达极显著水平；除坚果鲜重与“强特勒”差异不显著外，“西林3号”核桃坚果其它测定指标均明显优于“强特勒”、“香玲”及“西扶1号”3个品种，且与3个品种相同指标的差异均达到极显著水平。核桃坚果与其青果主要外观性状之间存在显著相关性，其中，坚果仁重与青果单重、坚果仁重与青果横径、坚果仁重与青果线径、坚果纵径与青果纵径之间的相关系数均在0.91以上，应用回归方程，可以通过青果外观性状提前估算其坚果大小及鲜果仁重。
- Abstract:
- Taking ‘Xilin 3’，‘Xifu 1’，‘Xiangling’ and ‘Qiangtele’ walnut fruits as materials,the fruit and nut appearance character indexes were determined.The results showed that，each fruit index of ‘Xilin 3’ walnut performed better than other three walnut varieties，and the differences with other varieties of the same index had reached a very significant level;kernel weight of ‘Xilin 3’ walnut had no significant difference with ‘Qiangtele’，while other nut indexes of ‘Xilin 3’ walnut performed better than ‘Xifu 1’，‘Xiangling’ and ‘Qiangtele’，and the differences with other varieties of the same indexes also reached a very significant level;appearance character indexes of walnut fruit and nut had a significant correlation，that the correlation coefficient of kernel weight and fruit weight，fruit transverse and side diameter，nut longitudinal diameter and fruit longitudinal diameter were all over 0.91，and with fruit appearance character index，nut size and kernel weight could be estimated through regression equation.
