In this article we will discuss about the genetic engineering of flower colour. Ornamental plants having aesthetic value of flower colour is significant from the consumer’s point of view. Certain ornamental plants like roses, tulips, carnations and chrysanthemum occupy more than 60% of the cut flower industry. Flower colour has been understood biochemically and genetically. Synthesis of colour pigments is [...]
In this article we will discuss about the phylogenetic organs of flower. Most Taxonomists agree that angiosperms form a natural group. They are monophyletic that is, their origin is from one ancestor only. But the ancestor is to be identified definitely. The ancestral organs from where the extant floral parts evolved are not known. Wilson (1982) regards that angiosperms evolved [...]
In this article we will discuss about the process of transition in flowers, explained with the help of suitable diagrams. Reproductive apex exhibits plastochron size fluctuations during the development of floral parts/primordia. The apex may widen and become slightly flattened. In Liriodendron the apex becomes conical and elongated. Smith (1966) reported the horizontal and vertical enlargement of the apex in [...]
