ABSTRACT In this study, the effect of different rootstocks on watermelon plant growth, fruit yield and quality were studied by comparing grafted plants with non-grafted ones under low tunnels for early production and later open field growing conditions. The watermelon ( Citrullus lanatus (Thunb.) Matsum and Nakai ) cultivar Crispy was grafted onto TZ-148 and RS-841, commercial hybrids of C . maxima x C . moschata and an experimental rootstock ( Lagenaria siceraria ) cv. 64-18. Non-grafted plants were used as control. Grafting significantly affected plant growth. Control plants had short main stem, less number of lateral vine and low root dry weight. Fruit yield was positively influenced by grafting when compered with the control under two growing conditions. There was a difference among grafted plants, 64-18 was significantly poor for yield characteristcs than the other rootstocks. Detrimental effects were not determinated in fruit quality such as fruit index, rind thickness and soluble solid contents on grafted plants. These results showed that the use of grafting can be an advantageous alternative in watermelon production. Grafted plants improved plant growth and yield without any harmfull effects on fruit quality. The positive effects of grafting can change according to the rootstock being used.

    ABSTRACT: This study was conducted to examine the effect of grafted peppers (Capsicum annuum) on different rootstocks on fruit quality. Three pepper cultivars, 'Nokkwang', 'Saengsaeng Matkkwari', and 'Shinhong' were grafted onto five commercial rootstocks that are known to be resistant to Phytophtora blight. Non-grafted or auto-grafted peppers were used as controls. Grafted plants were grown during two consecutive harvest periods by semi-forcing culture (April to August) and retarding culture (September to March the subsequent year). Full size green fruits were harvested and weighed weekly from June to August (Semi-forcing culture) and from December to March of the subsequent year (Retarding culture). The fruit size, weight, flesh thickness, and firmness were measured every month. Total marketable yield was not significantly influenced by either auto-graft of 'Nokkwang', 'Saengsaeng Matkkwari', and 'Shinhong' of pepper or grafted with the five commercial rootsctocks. By contrast, grafting influenced the apparent fruit quality of peppers. Fruit characteristics differed depending on the rootstock cultivars. However, the fruit characteristics of rootstock did not affect the fruit characteristics of scion grafted onto that rootstock. Fruit characteristics in each treatment differed among harvest time (first, second, and third harvest). Fruit quality parameters were also different as affected by the harvest period. In conclusion, apparent quality and textural property of pepper fruits were influenced by not only grafting with different rootstocks but also by the harvest period and harvest time. Accordingly, rootstock/scion combination, the scion variety and the harvest period must be carefully chosen to get the desired optimal fruit quality.
