| Abstract: | • Background
Production of seedlings, especially in containers, requires simultaneous germination and emergence. Mechanical scarification
often speeds up the growth of embryo axes, increases the percentage of germinating seeds and seedling emergence. Cutting off
the distal ends of cotyledons is a mechanical scarification technique sometimes used in the container production of oak seedlings.
However the consequences of this procedure for seedling development are little known. We wanted to determine these effects
on development and metabolic changes of pedunculate oak (Quercus robur L.) seedlings. |
