تكوين نباتات جديدة من كالس الأجزاء النباتية المختلفة لنبات فول الصويا (G. max L.)‎

الملخص EN

Callus was induced from different explants (hypocotyls cotyledonaiy leaves, leaves, primary leaves, roots and shoot tips) of Soybean & tagy seedlings on MS medium containing BA and NAA, or BA, NAA and 2,4-D.

The results showed that there were differences in stimulation, growth and morphology of callus derived from different explants.

Such diffcfeoces were attributed to the type of explants and growth regulators used.

Stems and cotyledons parts were the best source for callus production.

Moreover, addition of 2,4-D to MS medium sustained the regeneration of plants utilizing the callus of shoot tips, primary leaves, hypocotyls and cotyledonary
