Influence of ovule perforation, plant growth regulators, andl-glutamine on in vitro growth of immature peach embryos Academic Article uri icon


  • Ovule perforation technique and media components (plant growth regulators and l-glutamine) were tested on in vitro growth of immature (<3 mm) embryos of "Springcrest" and "Earligrande" peaches. Ovule perforation was 2 to 4 times more effective in promoting embryo growth than leaving ovules intact. l-Glutamine (400 mg·liter -1) promoted an increase in growth but could not be used with indole-acetic acid plus kinetin because an antagonistic effect on embryo growth occurred. The use of these exogenous plant growth regulators did not increase embryo growth over in vivo growth. © 1993 Tissue Culture Association.
