- 摘要:
- 以核桃成熟果实为材料，测定了5个青果外观性状和7个坚果外观性状，分析了青果性状、坚果性状及青果与其坚果性状之间的相关性。结果表明：核桃青果外观性状之间均呈极显著的线性正相关关系；核桃坚果三径之间均呈极显著正相关关系，坚果鲜重与坚果三径和坚果仁鲜重呈极显著正相关，坚果仁鲜重与坚果三径、坚果鲜重和坚果出仁率均呈极显著正相关，而与坚果壳厚呈极显著负相关；坚果出仁率仅与坚果仁鲜重呈极显著正相关，而与坚果壳厚呈极显著负相关，与坚果纵径呈显著正相关；坚果壳厚与坚果横径、坚果纵径、坚果仁鲜重及坚果出仁率均呈极显著负相关，与坚果线径呈显著负相关；核桃青果5个性状与坚果三径、坚果鲜重、坚果仁鲜重及坚果出仁率等6个坚果外观性状之间均呈极显著正相关，与坚果壳厚均呈极显著负相关；该研究列出了各个性状间的线性回归方程和相关密切程度。
- Abstract:
- Taking ripe fruit of walnut as material，the exterior characters of the fresh fruits from 5 walnut varieties and the nuts from 7 walnut varieties were measured during the harvest time，the exterior character of the fresh fruits，the nuts and the correlation between them were analyzed.The results showed that:there was a positive linear correlation of exterior characters between fresh fruits and nuts，it was the same relation among transverse，longitudinal and line diameter.There was a positive correlation of fresh nut weight between diameter and kernel weight like the correlation between the kernel weight and diameter，fresh nut weight，kernel rate，but it was negative correlation between the kernel weight and the thick of nuts.There was a positive correlation between nut rate and weight，longitudinal diameter，and it was negative correlation with the thick of nuts.It was a positive correlation between the thick of nuts and transverse diameter，longitudinal diameter，nut weight，nut rate，it was negative correlation with line diameter.The 5 characters of the fresh fruits was positive correlation with diameter，fresh weight and rate of nuts，it was negative correlation with the thick of nuts.The equation of linear regression and the correlation were also being present.
