Micropropagation of Globe Artichoke (Cynara cardunculus L. var. scolymus).
2013
The globe artichoke (Cynara cardunculus L. var. scolymus) is a perennial plant cultivated in the Mediterranean region and the Americas for its edible young flower heads. Although vegetative propagation by offshoots or by “ovoli” (underground dormant axillary buds) has been the primary method of propagation, the potential for the diffusion of diseases and the phenotypic variability can be very high. The propagation of this species by axillary shoot proliferation from in vitro cultured meristems produces systemic pathogen free plants and a higher multiplication rate as compared to that obtained by conventional agamic multiplication. Axillary shoot proliferation can be induced from excised sho…
The effect of explant cut and cytokinin type on micropropagation of fig (Ficus carica L.) 'Brown Turkey'
2017
This study was conducted to micropropagate 'Brown Turkey' fig, one of the most popular cultivars in California, USA for fresh and dried uses. Nodal segments cut lengthwise or not were cultured on Woody Plant Medium containing 0.3, 1.0 or 3.0 μM of N6 benzyladenine (BA) or kinetin in a 3 (concentrations) × 2 (cytokinins) × 2 (explant types) factorial experiment. 60% of explants became contaminated with various microbes when the standard protocol of washing shoots for 3 h under running tap water. Microbial contamination was nearly eliminated when the running water rinse and the use of an ascorbic acid dip were eliminated. Phenolic exudation was not a problem. Shoots grew longer with more leav…
