摘要：
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.
