Abstract

This research was carried out at Al-Ghab, Hama Province, during the two agricultural seasons 2016 and 2017, to study the effect of some rootstocks on productivity quantitatively and qualitatively. The experimental design was randomized completely blocks design. The hybrid muskmelon Palmeta F1 was grafted on three rootstocks namely; Forza F1, Jawad F1, and Lagenaria siceraria. Mol, in addition to the control, and each treatment replicated 4 times. The results showed that grafting contributed to a significant increase in the average of total productivity and marketing, which attained the highest values in the plants grafted on pumpkin rootstock  Lagenaria siceraria. Mol (5.85, 5.29 tons/dunum) compared to the control (2.33, 1.98 tons / dunum), respectively. Also, the grafted plants showed a significant increase in the thickness of the cortex, the size of the seed cavity and the firmness of the fruits. The chemical content of the fruits showed a significant decrease in the ratio of dry matter and total soluble solids of the plants that were grafted on the Jawad F1, and pumpkin Lagenaria siceraria. Mol rootstocks compared with the control and the plants that were grafted on Forza F1 rootstock. While the fruits of the grafted plants had high content of vitamin C compared to the control which gave the lowest value (12.49 mg/100 g).

Abstract

The research was conducted at Faculty of Agriculture, Damascus University/Syria, with the help of Scientific Agricultural Research Center in Latakia during 2013 and 2014seasons. Three rootstocks were used i.e. Sour orange, citrumelo and troyer citrange, to study some factors affecting the success of micrografting technique (concentrations and periods of sterilization, rootstock, shoot tip size, type of nutritive medium and the grafting method). The nutritive medium was prepared, and the shoot tips was isolated from Navel orange source, then the micrografting was done for the three rootstocks. The results showed that contamination and germination of seeds were affected by the concentration and period of sterilization. Also, this effect varied among the three rootstocks that were used. Success of grafting depended on the rootstocks. Citrumelo rootstock gave the highest grafting rate (54.17 %). Regarding shoot tip size, the results revealed that this character played a crucial role for the success of micrografting. The highest grafting rate was achieved (62.50%) by using shoot tips of about 1 mm sized. Also, the results showed that grafting method and nutritive medium had vital role on the success of micro-grafting. Micro-grafting rates were better by using liquid medium (45.83%) and with the application of inverted T-incision method (75%).

Key words: Navel orange, In vitro micrografting, Rootstocks.
