Internal levels of plant growth regulators during in vitro culture of wild cherry ( Prunus avium L

چکیده
In vitro micropropagation of wild cherry is presently one of the main commercial ways to clonally propagate this species (Cornu and Boulay, 1986). In order to extend this technique to a large number of clones, it seems necessary to improve our knowledge of the behavior of the explants during the in vitro culture. Since plant growth regulators (PGR) play an important role in this technique (Margara, 1961 ), our attention was drawn to the effect of exo-

New reports of endophytic fungi associated with cherry (Prunus avium) and sour cherry (Prunus cerasus) trees in Iran
Endophytic fungi constitute a remarkable multifarious group of microorganisms live within plants tissues without causing any obvious negative effect. Endophytic fungi have been found in every plant species examined to date. During an investigation on endophytic fungi, 123 fungal isolates were obtained from healthy twigs and leaves of cherry (Prunus avium) and sour cherry (P. cerasus) trees in I...

Effects of various culture media and growth regulators on micropropagation of cherry rootstock, M × M60 were investigated in the present study. Stem cuttings of the current season growth were taken from mature stockplants and cultured on the establishment medium after disinfection. After four weeks, elongated shoots were cut and subcultured on the proliferation media including MS, DKW, QL and M...
متن کاملEffect of Arbuscular Mycorrhiza on Growth and Physiological Behavior of PHL-C Rootstock
PHL-C is one of the dwarf sweet cherry rootstocks which is a hybrid between P. avium L. × P. cerasus L. Direct rooting of sweet cherry rootstocks is difficult which can be solved by using in vitro propagation. Transfer of plantlets from in vitro to ex vitro limit the use of micro propagation, because of weak root systems and low survival rates. This study was conducted in order to select the be...
