in study was conducted in two separate experiments in 2011-2013 in seeds and plant improvement institute. in the first experiment, status growth scion and resistance to spring late frost and content proline in 10 genotypes and cultivar almond, grafted on gf677 rootstock included touno, non pariel, shokofeh, sahand, mamayi, shahrood 12, a200, 1-25, 1-16 and 13-40 with 10 replication as a complet...

thermotherapy is one of the tristeza management methods that was used in this study. thus 36 ͺ ‘thomson navel orange’ scions on soure orange rootstocks were placed in temperature controlled chamber (tcc) to investigate the effect of thermotherapy on elimination of tristeza virus. at first, the scions were inoculated by grafting of infected buds and after six months tested by elisa to ensure con...

The objective of this study was to evaluate the stenting (grafted cutting) propagation of commercial pomegranate cultivars as scions on drought tolerant genotypes as rootstocks. The effect of drought stress on nine pomegranate rootstocks was analyzed. Cultivars including ‘Daneshgah 13’, ‘Daneshgah 32’ and ‘Daneshgah 8’ that were used as rootstocks showed the maximum drought tolerance among the ...

In the last five decades, use of rootstocks and scions has changed, along with their systems cultivation. Associated climate change, fruit trees face new ecological phytopathological challenges. Rootstocks affect generative vegetative performance a scion, such as productivity, span nonbearing period, growth vigor, shelf-life quality fruits. According to recent study, they also frost tolerance f...

Fifty-seven scions from an adult purple-leaved plum tree were grafted onto the crown of a 6-year-old Yuhuang plum tree and compared to the control of a non-grafted tree. The floral buds of the purple-leaved plum were fully removed before blossoming to avoid sexual hybridization between the two species. The seeds of the Yuhuang plum were picked in July and sown in the spring after stratification...
