This study was conducted to evaluate the effect of preservative solutions on vase life, number of bacteria in the end of stem and in vase solution of cut gerbera 'Double Dutch' and 'Red Explotion'. Cut flowers were pulse-treated with nano-silver (2, 4, 6, 8 or 10 mg L-1) and thymol (12.5, 25, 50, 75 or 100 mg L-1) +5 % sucrose. Experiment was conducted in completely randomized design with 5 rep...

An in vitro mass propagation protocol was developed for Gerbera (Gerbera jamesonii Bolus) var. orange using flower bud explants. The young (7 days) explants were found to be suitable culture and highest (100%) callus induction obtained MS medium supplemented with 5.0 mg/l BAP 1.0 NAA. maximum shoot regeneration (95%) the number of shoots (10) observed 6.0 0.3 multiplication frequency (60) only ...

A major component of the evaluation of biological control agents is the study and comparison of their biology, including the reproductive mode. In hymenopteran parasitoids, reproductive modes include thelytoky and arrhenotoky. Since a thelytokous population produces only females, it is assumed that they may be better suited for biological control than an arrhenotokous population. Here we compar...

A high frequency shoot organogenesis and plant establishment protocol has been developed for Gerbera jamesonii from ex vitro leaf derived callus. The optimal callus was developed on Murashige and Skoog (MS) basal medium supplemented with 0.4 mg L 6-benzylaminopurine (BAP), 4.0 mg L -naphthalene acetic acid (NAA) and 3% (w/v) sucrose. Two callus types differing in their structures and growth rat...

The plant pathogen Botrytis cinerea can infect undamaged plant tissue directly by penetration of the cuticle. This penetration has been suggested to be enzyme-mediated, and an important role for cutinase in the infection process has been proposed. In this study the expression of the cutinase encoding gene cutA of B. cinerea was analyzed using a cutA promoter-GUS reporter gene fusion. Transforma...
