Abstract

Precipitation is the primary water source of desert plants in arid regions. Nitraria tangutorum Bobr., a typical desert plants in Minqin County of Gansu Province, was used to reveal the effect of precipitation enhancement on the growth of desert plants. The morphology of N. tangutorum Bobr. branch and leaf was analyzed under different simulated rainfall gradients (increased 0%, 25%, 50%, 75% and 100% of mean annual precipitation respectively). The results showed that the length, basal diameter and leaf number of N. tangutorum Bobr. branch were significantly promoted under 100% increased rainfall treatment in 2010 and 2011; the length, basal diameter and leaf number of N. tangutorum Bobr. branch was also promoted by the increased 75% rainfall treatment in 2011. The 75% increased rainfall had the most significant influences on the growth of absolute length of flower branch,the absolute basal diameter,the absolute number of new leaf and vegetative branch, the absolute number of new leave in June, and the growth of absolute number of mature leaf of flower branch, the absolute basal diameter and the absolute number of mature leaf of vegetative branch in September, the values were 1.20±0.35 cm, 0.012±0.004 cm, 4.35±2.51, 1.65±0.69 cm, 3.20±1.45, 2.15±0.69, 0.013±0.006 cm, and 2.20±1.10 respectively. The different morphological characteristics of N. tangutorum Bobr. branch, the absolute length of flower and vegetative branch growth, the absolute basal diameter growth and the absolute number of new and mature leaf growth significantly increased, and the threshold values in 2011 were lower than those in 2010. It was suggested that N. tangutorum Bobr. can adapt to different precipitation pattern by changing branch morphology.
