摘　　要：为探讨土壤水分条件对麦蓝菜生物量及王不留行黄酮苷（VR）含量影响,以盆栽麦蓝菜为材料,采用4种土壤水分（重度干旱、中度干旱、适宜水分和过湿水分）处理麦蓝菜,测定胁迫后15、30和45 d麦蓝菜根、茎、叶、种子生物量,以及VR含量和产量。结果表明,与适宜水分相比,土壤重度干旱、中度干旱、过湿水分均会降低麦蓝菜各器官生物量,而中度干旱能够显著提高麦蓝菜各器官中VR含量,当土壤水分为田间持水量的70%~75%时,可获得最佳的麦蓝菜生物量和VR产量。建议人工种植麦蓝菜时保持适宜土壤水分含量,以兼顾药材的产量和质量。We tested pot cultured Vaccaria segetaiis（Necr.） Gracke to study the effects of soil moisture on biomass and vaccarin（VR） content of V.segetaiis in four different kinds of soil moisture.We determined the biomass and VR content of different organs of V.segetaiis after 15,30 and 45 days in different soil water conditions.The biomass and VR content of V.segetaiis are affected significantly by the followed soil water conditions of severe soil drought,moderate soil drought,and excessive soil moisture compared with the control group,and VR content in different organs of V.segetaiis can be improved significantly in moderate soil drought condition.The best biomass and VR yield of V.segetaiis are in soil moisture of 70%75%of field capacity.Proper soil moisture was proposed to maintain to balance between yield and quality of this medicinal herb in production of V.segetalis.
