摘　　要：为探究平欧杂交榛子在咸阳地区的光合表现,以杂交大果榛子达维、辽榛3号、玉坠和美人指为试验材料,测定分析4个榛子品种的生长参数、光合参数、水分利用效率、叶绿素含量(SPAD)和氮含量。结果表明,生长参数大小均表现为达维>辽榛3号>玉坠>美人指,其中,达维的株高分别是辽榛3号、玉坠和美人指株高的1.12倍、1.29倍和1.42倍,叶面积分别是3个榛子品种叶面积的1.06倍、1.51倍和1.35倍;不同榛子品种的气体交换参数有所差异,辽榛3号的净光合速率(Pn)显著高于达维、玉坠和美人指,分别是3个榛子品种的1.10倍、1.08倍和1.11倍;叶片SPAD值和氮含量大小均表现为达维>辽榛3号>玉坠>美人指,其中,达维叶片SPAD值分别较辽榛3号、玉坠和美人指的SPAD值增加了2.60%、4.05%和12.96%,氮含量分别较辽榛3号、玉坠和美人指增加了1.90%、9.16%和12.30%。经隶属函数分析表明,4个榛子品种综合表现为达维>辽榛3号>玉坠>美人指。In order to explore photosynthetic performance of Corylus heterophylla Fisch.×Corylus avellana L.in Xianyang region,in this study,the C.heterophylla×C.avellana varieties of Dawei,Liaozhen 3,Yuzhui,and Meirenzhi were used as the test materials,the growth parameters,photosynthetic parameters,water use efficiency(WUE),chlorophyll content value(SPAD),and nitrogen content of the four hazelnut varieties were determined and analyzed.The results revealed that the order of the growth parameters of the varieties was ranked as follows:Dawei>Liaozhen 3>Yuzhui>Meirenzhi.Plant height of Dawei was 1.12,1.29,and 1.42 time of those of Liaozhen 3,Yuzhui,and Meirenzhi,respectively,and its leaf area was 1.06,1.51,and 1.35 time of those of the three varieties.In addition,differences in gas exchange parameters were also observed among the varieties.The net photosynthesis(Pn)of Liaozhen 3 was significant higher than that of Dawei,Yuzhui,and Meirenzhi,and was 1.10,1.08,and 1.11 time of that of the three varieties,respectively.Leaf SPAD values and nitrogen contents of 4 species hazelnut varieties were ranked as Dawei>Liaozhen 3>Yuzhui>Meirenzhi.Leaf SPAD values of Dawei were higher by 2.60%,4.05%,and 12.96%when compared to that of Liaozhen 3,Yuzhui,and Meirenzhi.The nitrogen content of Dawei was observed to be higher by 1.90%,9.16%,and 12.30%when compared to that of the three varieties,respectively.Their overall performance was ranked using membership function analysis as Dawei>Lioazhen 3>Yuzhui>Meirenzhi.
