Abstract

|
|
Two oriental melons cultivars, ‘Geumssaragi Euncheon’(GSEC) and ‘House Eunchon’(HEC), were grafted onto different rootstocks and the growth, mineral contents and fruit quality were examined. The seedlings grafted onto‘Geumtozwa’rootsticks showed about 10% defected seedling loss(wilting or dwarfing0as compared to the little or no loss in the seedlings grafted onto ´Sintozwa´ or ´Chamtozwa´ rootstocks. The seedings grafted onto ´Sintozwa´ or ´Chamtozwa´ rootstocks also exhibited better vine growth as compared to the intact seedlings or the seedlings grafted onto ´Geumtozwa´ rootstocks. The fruits growth, as measured by fruits length, fruit diameter and fruit fresh weight, was accelerated by the rootstocks especially by ´Sintozwa´ and ´Chamtozwa´ . Intact oriental melons showed the highest soluble solids content in the fruit pericarp followed by ´Chamtozwa´ rootstocks. Sucrose contents were higher in the seedling grafted onto ´Sintozwa´, whereas higher glucose and fructose contents were measured in intact GSEC fruits or HEC fruits on ´Chamtozwa´ rootstock. As compared to the intact plants, the seedling grafted onto ´Sintozwa´ rootstock showed higher N. P and K and lower Ca and Mg contents in leaves, stems, roots and fruits. ´Geumtozwa´ rootstock, developed specially for oriental melons, showed very similar pattern of mineral absorption or distribution as compared to the intact plants.
