'BOTANICAL STUDIES ON Coriandrum sativum L. OF THE FAMILY APIACEAE.

Acute difficulties are experienced by taxonomists in arriving at satisfactory classifications of various parts of Apiaceae due to little information available on morphological aspects of different umbelliferous species. Thus, Coriandrum sativum L. ( Coriander) was chosen to undertake a careful study dealing with germination of seeds and external morphology of vegetative and reproductive growth of this plant throughout the consecutive stages of its entire life span. Such knowledge may fulfill information acquisition in this concern. The morphology of vegetative growth includes: plant height, length of the main stem, number of internodes of the main stem, length and diameter of successive internodes of the main stem, number of secondary branches, length of secondary branches, number of leaves per plant and fresh weight of leaves per plant. The morphology of reproductive growth includes: number of compound umbels per plant, number of umbellets per compound umbel, total number of umbellets per plant, number of flowers per umbellet, total number of flowers per plant, total number of cremocarps per plant, yield of cremocarps per plant and specific weight of cremocarps.
