Peculiarities of seeds germination and seedling development in Sterculia coccinea Roxb. ex G.Don (Malvaceae)

Abstract

Ivan A. Savinov

Seed germination for Sterculia coccinea in room conditions was studied. Seed is germinating in the fruit (it is connected with capsule wall), but only after separating from maternal plant. Type of germination – epigeal, cryptocotylar, of Blumeodendron-type (because the seedling does not become free from seed envelops and testa remains persistent around the flat opposite cotyledons on the top of hypocotyl, and they shed together with these organs). Different time for seed envelops and cotyledons shed from the seedling was determined.
