- Title
Dormancy in Seeds of Anona crassiflora Mart.
- Authors
RIZZINI, CARLOS TOLEDO
- Abstract
The seeds of Mart., an important tree of the Brazilian cerrado, have been found to take about 8 months for germination to commence, and some 35-70 d more to achieve it fully; such seeds must remain in moist ground all this time. A poorly developed embryo, little more than a hyaline mass of cells, was all that could account for the delayed germination. Inhibition by extracts of seed parts was negligible. In after-ripening is related more to morphological changes in the embryo than to chemical changes. As the seed cannot endure even a brief sojourn in dry soil, vegetative reproduction is the means by which the tree spreads into new areas.
