Impairment of chloroplast development and sink strength by blockade of light in chloroembryos of Cyamopsis Tetragonoloba (L.) Taub.
In many members of Fabaceae synthesis of chloroplast pigments
takes place even when the embryo is deep inside the
fruit. Blockade of light totally etiolated the embryos of
developing Cyamopsis fruits upto 16-18 days after anthesis
(DAA), whereas the pigments of the mature embryos, when
shaded, were not significantly affected. Upon illuminatio
resynthesis of green pigments by etiolated embryos occurred
both l n v i v o and in vitro more significantly during the
early stages of growth of the embryos (upto 18 DAA). Shading
of developing fruits at different growth stages of embryos,
reduced the growth of sink. The results are discussed in
relation to the importance of light on embryo greening and
dry matter production
