Estudo do poder germinativo da semente de manga

Resumo

The author studied the storage of seeds of mango trees with the aim of Keeping high its ability of germination. Seven means of storage were tried, with two temperatures: environment temperature (22 to 27 degrees Centigrade) and cold store room (5 degrees centigrade). The methods of storage tried were: 1 - The frewit kept complete. 2 - Seeds taken within the stone. 3 - Seeds taken out of the stone. 4 - Stones heated with a Fungicida (Zineb). 5 - Stones cut laterally and heated with a fungicide (Zineb). 6 - Seeds (out of sones) heated with Zineb. 7 - Stones steatified with sand. The best results were obtained for seeds kept within whole fruits, probably owing to protection provided by outer layers. The use of fungicide imposed the sanitary aspect of seeds and stones. Storage in cold store room (5 degrees Centigrade) injured the seeds and stones in all cases. Germinating power was kept high up to 70 days for complete fruits. It seems that biggers fruits were more favorable to keep high the ability of theirs seeds to germinate.
