It gives me great pleasure to fancy that I see radicles of orchid seed penetrating the sphagnum. |
Callus was formed on cotyledons, hypocotyls, and radicles of embryos. |
Each acorn was cleaned, weighed, and examined for insect larvae exit holes, splits in the shell, and protruding radicles. |
Radicles or plumules were excised from the embryos and similarly incubated. |
Are the sheaths found on certain radicles strictly confined to monocotyledonous plants. |
