Abstract: Whole embryos of Pinus resinosa excised at various stages of development and cultivated in vitro showed different degrees of potential for growth and differentiation. The influence of physico-chemical environment was maximum during the early stage of development. The suspensor cells could be induced to form budding embryos, or their growth could be arrested. The growth of the suspensor or its lack in vitro was a function of physiological response. Segments of embryos cultivated in vitro showed gradients in potentiality for differentiation in relation to their positions in the embryo and also within themselves in relation to . their basal and apical ends. Alternative developmental sequences were observed during regeneration in the segments. The experiments also showed that polyembryony was due to constitutional potentialities in the young embryonic tissue and thus all the cells of an embryonic group could be considered as “embryo initials” under appropriate environmental conditions.
