DEALING WITH STOP-GO GERMINATION IN FLOWER SEEDS |
| Author: | B. Atwater |
| Abstract:
Observations of germination problems in flower seeds and a review of current experimental work show that dormancy and germination requirements are closely related to the maturity of the embryo and the structure and permeability of seed coat coverings in mature seed. It has also been shown that seed morphology shows a remarkable similarity in related plant families and follows a progressive developmental pattern phylogenetically. Such an orderly plan lends itself to meaningful solutions in understanding the mechanism of promoter-inhibitor balance and the trigger factor necessary for growth initiation. Flower seed plant families are arranged according to embryo development and seed coat characteristics. Observed physiological behavior is discussed. | |
