Fig. 3. Pistil receptivity and silique growth. (A) Receptivity period for Ler and fwf pistils examined by the removal of floral organs, except the pistil, at anthesis and controlled self-pollination on specific days after anthesis. (B) The relationship of floral position on the primary inflorescence meristem and final parthenocarpic silique length in male sterile pop1 (circles) and pop1 fwf (squares), emasculated fwf (diamonds) and male sterile pop1 ats fwf triple mutant (triangles). (C) Silique growth of pollinated Ler (Ler p), emasculated fwf and male sterile pop1 ats fwf compared to emasculated and unfertilized Ler (Ler up).
