基质接种贝莱斯芽孢杆菌对番茄穴盘苗耐旱性的影响
Effect of Bacillus velezensis on Drought Tolerance of Tomato Plug Seedlings
摘要
Abstract
The tomato variety'Zhongza 302'was selected to investigate the role of Bacillus velezensis(L-S60,L-H15,LPL-117)on the drought tolerance of tomato plug seedlings,which was sown into the substrate with Bacillus velezensis.It was found that compared with the control under drought stress,the height of the tomato plug seedlings was increased by 8.95%to 13.05%and survival rate was increased more than 6 percentage points.Besides,there was no significant difference existed between the three treatment groups.The increase of Mn and Zn content in stems and leaves of L-S60,L-H15 and LPL-117 treatments were respectively more than 30.94%,7.59%,and the decrease of Ca and Mg contents were respectively more than 9.48%and 15.93%.The proline content of leaves in treatment groups of L-S60,L-H15 and LPL-117 increased respectively 62.86%,78.27%and 40.29%on the 3rd day of drought stress,and the malondialdehyde content decreased respectively more than 2.34%,18.96%and 7.94%on the 8th day of drought stress.This indicates that the substrate inoculation with Bacillus velezensis can effectively improve the drought tolerance and promote the growth and development on tomato plug seedlings.关键词
