Effect of Grafting on Watermelon Plant Growth, Yield and Quality
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.

- "In many cases, a yield increase has been observed in grafted watermelons (Alexopoulos et al., 2007; Ioannou et al., 2002; Ozlem et al., 2007; Proietti et al., 2008; Yetisir and Sari, 2003). In our study, which was conducted in disease-free soil, the yield of most grafted watermelons was not statistically different from that of their nongrafted or self-grafted counterparts (Fig. 4). "
ABSTRACT: Watermelon grafting is on the rise worldwide as an agrotechnology aimed at preventing soilborne-pest damage. Grafting watermelon on Cucurbita rootstocks may negatively affect fruit size, shape and quality. However, grafting watermelon on watermelon rootstocks can prevent these negative effects. Twenty-one exotic watermelon accessions were evaluated as potential sources for watermelon rootstock breeding programs. Most of the watermelon accessions tested in the field as rootstocks for the mini-watermelon ‘Extazy’ gave yields similar to the nongrafted and self-grafted ‘Extazy’. Four accessions: WAN, PI 457916, PI 307750 and PI 307609, produced significantly lower yields. The accessions BDA, CON, MAL, PI 296341 and PI 307609 were selected for detailed evaluation due to their previously found tolerance to soilborne pathogens. No difference was found in the total fruit quality index between nongrafted ‘Extazy’ fruit and ‘Extazy’ fruit from plants grafted on the different watermelon accessions. Fruit weight from plants grafted on Cucurbita rootstocks was higher than that from plants grafted on ‘Extazy’ or on the other watermelon accessions. No bitter flavor and no cucurbitacin were present in ‘Extazy’ fruits of plants grafted on bitter fruit watermelon accessions. Thus the examined exotic watermelon accessions did not adversely affect fruit quality and can be used as a basic germplasm for watermelon rootstock breeding. The most promising accession is PI 296341.Scientia Horticulturae 01/2014; 165:196–202. DOI:10.1016/j.scienta.2013.11.010 · 1.37 Impact Factor

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.Wonye kwahak kisulchi = Korean journal of horticultural science and technology / 12/2013; 31(6).

- "reported a higher rate of hollow heart incidence in ungraft ed watermelon plants than in those that had been graft ed. Results of this study are in agreement with previous studies that concluded that bottle gourd rootstocks can be used in watermelon production without signifi cant detrimental eff ects on fruit quality parameters (Yetisir and Sari 2003; Miguel et al. 2004; Alan et al. 2007).

ABSTRACT: The rootstock potential of 21 bottle gourds (Lagenaria siceraria) collected from the Mediterranean region (Turkey) was investigated for watermelon with regard to plant growth, yield, and fruit quality. The Crimson Tide watermelon cultivar was used as a scion and 2 commercial rootstocks (L. siceraria) were also used for comparison. In greenhouse conditions, the survival rate of grafted plants and the eff ect of rootstocks on plant growth were determined. The grafted plants were planted under low tunnels in early spring and the eff ects of the rootstocks on early yield, total yield, and fruit quality were evaluated. The survival rates of the grafted plants varied from 83% to 100%. Survival rates of those with commercial rootstocks and local rootstocks were similar. Plants grafted onto 20-02, 31-09, 31-43, 35-01, and 46-03 were more vigorous than ungrafted control plants. Compared to the control plants, grafted plants had 37% to 80% higher plant dry weight. All of the grafted plants except CT/Macis produced a higher yield than the control plants. The plants grafted onto 6 of the local rootstocks had significantly greater total yields than those grafted onto the commercial rootstocks. Among the local bottle gourd landraces tested, the 01-16, 07-45, 20-06, 31-09, 31-15, and 46-03 were found to be promising genotypes with regard to total yield. Early yield was not significantly affected by rootstock. The quality parameters of the fruits harvested from the grafted and control plants were found to be similar except for a limited number of graft combinations. It was concluded that germplasm from Turkish bottle gourds has a high rootstock potential for watermelon with regard to the investigated parameters.Turkish Journal of Agriculture and Forestry 01/2012; 36(2):167-177.
