摘要

为探讨锥栗不同授粉组合果实中矿质元素是否也存在花粉直感效应,应用全自动间断化学分析仪和原子吸收光谱法测定了"华栗1号"、"华栗2号"、"华栗3号"和"黄榛"四个锥栗主栽品种自交、异交以及自然授粉的子代坚果中主要矿质元素的含量。结果表明,锥栗不同授粉组合坚果的N,P,K,Ca,Mg,Fe,Zn和Mn八种矿质元素含量差异较为显著,其矿质元素具有明显的花粉直感效应,尤其是铁、锌元素受花粉直感作用的影响较大,"华栗2号"×"黄榛"授粉组合果实铁、锌元素含量最高,分别为162.13和41.79μg·g~(-1);"黄榛"×"华栗1号"授粉组合果实中Mn元素含量最高为165.67μg·g~(-1),为锰微肥的利用提供了参考;通过主成分分析,评价出19个组合中在矿质元素方面表现最优的授粉组合为"华栗2号"×"黄榛"。该研究结果可为锥栗生产上合理配置授粉树和改善果实品质提供科学的依据。
        To elucidate the xenia effects of mineral elements on different pollination combinations in Castanea henryi,using the chinquapin cultivars"Huali No.1","Huali No.2","Huali No.3"and "Huangzhen"as materials,we investigated the xenia effects of mineral elements in C.henryi by auto dicsrete analyzers and atomic absorption spectrometry.Twenty combinations of self-,cross-,and natural pollination were undertaken.The results revealed that eight mineral elements of Castanea henryi seeds were significant differences.Xenia obviously has its mineral elements,especially iron and znic.The fruit of"Huali No.2"×"Huangzhen"showed the highest iron and zinc content,which were 162.13 and 41.79μg·g~(-1),respectively.The fruit of"Huangzhen"×"Huali No.1"showed an increased manganese content of 165.67μg·g~(-1),which provides a reference for the utilization of this variety as a manganese fertilizer.Through principal component analysis,the best combination was"Huali No.2"×"Huangzhen"in the 19 combinations.The results can give a basis for planting design of varieties and improving fruit quality in C.henryi.
