doi:10.7668/hbnxb.201751177

Abstract

Abstract: A pot experiment has been conducted to explore the compensation effect on dry matter accumulation induced by successive drought and re-watering. The hybrid maize and its parents were used with two treatments, which was sufficient water supply as CK, and successive drought and re-watering with three times (DR) as T. The results showed that successive drought and re-watering significantly decreased total dry matter accumulation of male parent for 19.9%, while it was not differed in hybrid and female parent when compared with CK. Dry matter accumulation of female parent was higher in aboveground than in belowground in initial two times of DR, while proportion of dry matter distribution in belowground after three times DR increased, and the dry matter accumulation of male parent showed that belowground was higher than above ground in three times DR, which resulted in higher root/shoot ratio than CK for 33.2% and 5.8% in female and male parent respectively. The root/shoot ratio of hybrid maize in each time of DR was lower than CK, which leaded to lower root/shoot ratio by 7.3% compared to CK. The compensation of shoot growth in hybrid maize increased after three times of drought and re-watering, while it was not showed in root growth. The growth compensation of the two parents were significantly decreased both in shoot and root. The results revealed that compensation effect was more obvious in shoot dry matter accumulation of hybrid maize. This could be used in maize cultivation to improve hybrid maize drought resistance by successive drought and re-watering during seedling stage, by which to increase dry matter accumulation and water use efficiency in seedling of hybrid maize.
