an investigation of type and state of culture medium and date of ovule and embryo separation on embryo rescue success in grapevine cv. flame seedless
flame seedless is one of the most important and commercial table grape cultivar that is used for breeding program due to its specific characteristics of fruit high production. in order to breed new seedless grape cultivars and with considering importance of selecting seedless varieties as a female parent to increase the production rate of seedless offspring in a breeding cycle, embryo rescue te...
متن کاملEffects of drought stress on total phenolics, phenolic acids, polyamines and some organic acids in two important Iranian grapevine cultivars
This study was conducted to assess the induced-changes in the content of total phenolics and individual phenolic acids, total and individual polyamines and some organic acids in the leaves of two important Iranian grapevine cultivars under different durations of drought stress, and to determine their involvement in grapevine drought tolerance. For this purpose, ‘Yaghuti’ as a drought-toler...
متن کاملeffects of putrescine and chlormequat pre-flowering treatment on embryo rescue technique success in diallele crosses of grape cultivars flame seedless, perlette and yaghooti
seedless grapes are widely grown all over the world. embryo rescue technique proved to be able to overcome the problem of embryo abortion in seedless grape breeding program. since, the efficiency of this technique is not desirable, so a lot of efforts have been done in different directions in order to improve this technique. this study was conducted in two separate experiments in which chlormeq...
متن کاملBreeding new seedless grape by means of in vitro embryo rescue.
This project aimed at breeding new seedless grape cultivars by embryo rescue through three hybridization methods: 1) using cross-breeding between seedless Vitis vinifera cultivars and wild Chinese Vitis spp; 2) crossing with two seedless cultivars, and 3) hybridization between grapes of different ploidy. Genotype, sampling times, and media were confirmed to play important roles in this system. ...
متن کاملsome properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
