Abstract:
Root system of cucumber grafted seedlings were used as research object,the single factor test and multi-factor orthogonal experiment were carried out through high and low temperature stress.The results showed that effect of high and low temperature stress on the relative conductivity of grafting root and root activity was highly significant，which was higher effect than cultivation mode and grafting varieties；under high temperature stress，the root length of grafted seedlings increased，but the root fresh weight，root volume，root diameter and root number decreased，root relative conductivity increased，root vigor dropped，grafted seedling’s root apparent over growth phenomenon；under low temperature stress，the root length，root fresh weight，root volume，root diameter and root number significantly decreased，root relative conductivity increased，root vigor dropped，root of grafted seedlings developed slowly.The results suggested that high and low temperature stress affect the grafted seedling’s root normal growth，especially the high temperature stress.
