The effect of PGRs on in vitro shoot multiplication of GF677 hybrid (Prunus persica x P. amygdalus) rootstock on GNH medium

GF677 rootstock (peach ×almond) is an important rootstock for peach. It was produced by Bernhard in French at Grand Farad Research Centre in 1965. The present study focused on the effect of some PGRs on propagation and root induction on GNH medium as part of providing an applicable protocol for micro-propagation of mentioned rootstock. Results indicated that BAP at concentration of 0.5 mg/l plu...

Effects of Temperature and Season on In Vitro Establishment and Shoot Multiplication of Picea abies (L.) H. Karst

Plant propagation originated  from the mature tissues is the most desirable method in producing clonal plants, however microbial contamination usually is the main concern during regeneration processes. Moreover, commercial production of plants using clonal propagation is considered as high throughput method due to the   removal of seasonal barriers, lower cost of production with higher yield wh...

Control of Shoot Tip Necrosis and Plant Death during in Vitro Multiplication of Pistachio Rootstock UCB1 (Pistacia integrima × P. atlantica)

Pistachio is one of the most important nuts and its mass production using tissue culture techniques is of great importance. Micro-propagation has many complications. Contamination is one of the critical limitations in the establishment stage. This study focused on different NaClO and HgCl2 concentrations and exposure times. Shoot tip necrosis (STN) is one of the most common problems during larg...
