Effect of Cucurbita moschata Hybrids Rootstock on the Growth of Grafted Cucumber Seedling

doi:10.7668/hbnxb.2010.01.023

Abstract

Abstract: The compatibility and growth of grafted seedling which 3 C.moschata hybrids(including 360-3×112-2,077-2×112-2,360-3×635-1,which were screened out salt-tolerant hybrids at pre-stage test) and C.ficifolia as rootstocks,cucumber cultivar of Jinchun 2 as scion were studied by approach grafting and sprout insertion grafting using pot cultivation in greenhouse.The results showed that 3 C.moschata hybrid rootstocks were compatible with Jinchun 2 cucumber cultivar,but with lower survival rates than C.ficifolia rootstocks,differences in hypocotyls diameter and height between C.moschata hybrids and C.ficifolia rootstocks reduced the survival ratio of grafts,while with higher survival ratio of grafts by sprout insertion grafting than approach grafting.360-3×112-2 and 360-3×635-1 hybrids have the basic conditions of cucumber rootstock for their average leaf number,the largest leaf area,the fresh weight of roots and tops of grafted seedling no less than that of C.ficifolia rootstocks after grafting 20 days.And 360-3×112-2 hybrid would be a cucumber rootstock in vegetable production for it′s grafted seedling with higher root top ratio and stronger.
