초록
Five different poplar hybrids were tested for rescuing embryo to elongate in vitro plantiets after hybridization. Ovaries and ovules were cultured on Woody Plant Medium (WPM) supplemented with cytokinins, 6-benzylamine (BA) and zeatin. Multiple shoots were initiated from half section of capsule with immature embryos after 21 days from pollination and tiny shoots were formed after the expansion of cotyledons in ovule cultures. Germinating response was better in intraspecific hybrids
