in order to micropropagate of four vigorous rootstocks of pear, including pyrus betulifolia, konjuni, dargazi and gh1, effects of basic plant culture media (ms, ql and modified ql), cytokinins and auxins on productivity, proliferation and rooting were studied in seed and plant improvement institute, karaj. the highest amount of productivity for all rootstocks was observed in ql medium. among pe...

The magnitude of demand for planting materials in grape, mainly for rootstock genotypes indicates that micropropagation is inevitably necessary for their mass scale propagation. Therefore, the studies on micropropagation of four genetically different grape rootstocks namely Dogridge (Vitis champini), SO4 (V. riparia× V. berlandieri), H-144 (V. vinifera × V. labrusca) and 3309 C (V. riparia × V....

The use of micropropagated trees has been widely extended, since micropropagation is a convenient technique of vegetative propagation that shows a number of interesting advantages, mainly for woody fruit trees. However, only few studies can be found in the literature on the field performance of micropropagated trees. In this work, the performance of different micropropagated fruit-tree rootstoc...

abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...

micropropagated plantlets derived from three different grape rootstock genotypes namely, dogridge (vitis champini), so4 (v. berlandieri×v. rupestris) and ari-h-144 (v. vinifera×v. labrusca) were subjected to randomly amplified polymorphic dna (rapd) and inter simple sequence repeats (issr) analyses in order to evaluate their genetic stability and/or detect likely existing variations among in vi...
