Data are means of two experiments (n = 10). Means of Rf within the same column in each experiment followed with similar lowercase letters are not significantly different (p> 0.05). Similarly, means of Rf within the same row in each experiment followed with similar capital letters are not significantly different (p> 0.05); e Reproduction on cv. ‘Laura’ was tested using eye-plugs due to lack of in vitro plants of this cultivar.表2 七个马铃薯栽培品种对温室条件下四种马铃薯金线虫（Globodera rostochiensis）种群的响应。 栽培品种：‘Ecosse’、‘HAR2’、‘KIN1’、‘TGN’ 实验1： ‘Désirée’：28.43 d ± 12.0 a, A；14.73 ± 9.6 a, B；24.97 ± 10.5 a, A；37.27 ± 22.7 a, A ‘Connect’：31.70 ± 9.3 a, A；18.43 ± 5.2 a, B；30.84 ± 15.3 a, A；21.80 ± 9.4 a, A ‘Performer’：2.37 ± 1.3 b, A；1.74 ± 1.3 b, AB；2.45 ± 1.9 b, AB；1.18 ± 0.9 b, B ‘Rossini’：0.02 ± 0.1 c；0.00 ± 0.0 c；0.00 ± 0.0 c；0.01 ± 0.0 c ‘Caruso’：0.02 ± 0.1 c；0.00 ± 0.0 c；0.00 ± 0.0 c；0.02 ± 0.1 c ‘Amanda’：0.00 ± 0.0 c；0.01 ± 0.0 c；0.02 ± 0.1 c；0.05 ± 0.1 c ‘Laura’：0.00 ± 0.0；0.00 ± 0.0；0.00 ± 0.0；0.00 ± 0.0 实验2： ‘Désirée’：10.07 ± 1.5 a, A；8.11 ± 1.5 a, A；3.53 ± 0.3 a, B；12.92 ± 0.8 a, A ‘Connect’：7.47 ± 1.1 a, A；13.31 ± 1.9 a, A；2.42 ± 0.3 a, B；12.25 ± 2.7 a, A ‘Performer’：0.53 ± 0.1 b, AB；0.35 ± 0.1 b, B；0.85 ± 0.2 b, A；1.00 ± 0.3 b, A ‘Rossini’：0.00 ± 0.0 c；0.00 ± 0.0 c；0.04 ± 0.1 c；0.01 ± 0.0 c ‘Caruso’：0.00 ± 0.0 c；0.08 ± 0.3 c；0.00 ± 0.0 c；0.02 ± 0.1 c ‘Amanda’：0.00 ± 0.0 c；0.00 ± 0.0 c；0.00 ± 0.0 c；0.05 ± 0.0 c ‘Laura’：0.00 ± 0.0；0.00 ± 0.0；0.00 ± 0.0；0.00 ± 0.0 注：d 代表繁殖系数（reproduction factor, Rf）±标准误（standard error, SE）。本数据为两次独立实验的均值（样本量n=10）。同一实验中，列内具有相同小写字母的Rf均值间无显著差异（p>0.05）；同理，同一实验中行内具有相同大写字母的Rf均值间无显著差异（p>0.05）；e 因‘Laura’栽培品种缺乏离体植株，故采用眼状芽块接种体开展其繁殖能力测定。
