Mechanism and control of Solanum lycocarpum seed germination.

abstract：BACKGROUND AND AIMS:Mechanical perturbation is known to inhibit elongation of the inflorescence stem of Arabidopsis thaliana. The phenomenon has been reported widely for both herbaceous and woody plants, and has implications for how plants adjust their size and form to survive in mechanically perturbed environments. Wh...
