Effect of biocontrol agents on the number of galls and second-stage juveniles in soil and roots of cucumber infected with Meloidogyne incognita in the pot experiment.

aTreatments 2–5 were inoculated with approximately 2000 second-stage juveniles at the two-leaf stage of cucumber seedlings.bTreatments 1–2 were irrigated with 400 ml of tap water. The concentrations of S. racemosum and avermectin in treatments 3–5 were suspended in 400 ml of tap water and applied as a soil drench before sowing.cMSL = mean root length, MSL = mean shoot length, VI = vigor index. The values in columns followed by the same letter are not significantly different according to LSD (P = 0.05).cEach transformed figure is the average of four replicates±SD. The mean in columns followed by the same letter(s) did not significantly different according to LSD (p = 0.05).a. 处理组2至5在黄瓜幼苗两叶期接种约2000条二龄幼虫（second-stage juveniles）。 b. 处理组1至2浇灌400毫升自来水。处理组3至5中的总状串珠霉（S. racemosum）与阿维菌素均配制于400毫升自来水中，于播种前以灌根方式施入。 c. MSL代表平均根长（mean root length），MSL代表平均地上部长度（mean shoot length），VI代表活力指数（vigor index）。列中带有相同字母的数值经最小显著差数法（LSD，P=0.05）检验，差异无统计学意义。 d. 每项经转换的数据均为4次重复的平均值±标准差（SD）。列中带有相同字母组的平均值经最小显著差数法（LSD，p=0.05）检验，差异无统计学意义。
