B. preprandial blood glucose concentrations below 90 mg/dl and one-hour postprandial concentrations below 120 mg/dl minimize the incidence of macrosomia.

餐前血糖浓度小于90 mg/dl，餐后一小时浓度小于120 mg/dl使巨大儿的发生率降到最低。

B. Preprandial blood glucose concentrations below 90 mg/dL andone-hour postprandial concentrations below 120 mg/dL minimize theincidence of macrosomia.

餐前血糖浓度小于90 mg/dL，餐后一小时浓度小于120 mg/dL使巨大儿的发生率降到最低。

Seedlings under light absorbed more rutin than those in the dark at rutin concentrations of 60-80 μg/mL and absorbed less rurin at concentrations lower than 40 μg/mL or near 100 μg/mL. IAA (＞0.1 μg/mL) treatment promoted rutin accumulation and inhibited elongation of shoot axis and primary roots.
