Anatomical Study of Pigment Glands in the Seeds of Gosspium bickii
Semithin sections of pigment glands in Gosspium bickii were made and developmental and morphological characteristics of pigment glands were observed.Two types of pigment glands were divided,one type without cavities also called "gland primodium" which mainly distribute in hypocotyl and top of cotyledon,the other with central cavities which distribute in the basal of cotyledon.The data show that there were pigment glands in cotyledon and hypocotyl of G.bickii seeds.Pigment gland with cavities in cotyledon was first reported.
