One of the greatest problems faced in citrus growing during the process of seedling
formation is the slow germination and poor longevity of seeds. Factors such as water content in
seeds, environmental temperature and sort of package may influence the viability of seeds during
storage. In this sense, the objective of the work was to evaluate the behavior of the seeds of cravo
lemon either treated or not with fungicides, packed with four water contents and in three types of
packages during storage. After being harvested, the fruits were pulped mechanically and the seeds
degummed. To reach the desired water contents (44, 27, 13 and 9%) the seeds were submitted to
drying in the shade. A part of the sample of the seeds, was treated with the mixture of the fungicides
Tecto 100 (200g/100kg of seeds) and Captan 75 (300g/100kg of seeds) and the other part was
given no treatment. Next, the samples were packed into impermeable, semi-permeable and
permeable packages and stored under environmental conditions and cold chamber for nine months.
The experiment was conducted in the UFLA seed analysis laboratory. In three month, tests of
germination, of artificial aging, of water content and sanity were accomplished. The seeds of
cravo lemon behaved as recalcitrant from the sixth month of storage, mainth for the samples paked
in semipermeable and permeable pakages and storage in environment condition. The best conditions
for the conservation of seeds of cravo lemon were the packing with 44 e 27% of water content in
impermeable package and in cold chamber. The treatment with fungicide of seeds at the moment
of the storage is also advised for greater safety in the maintenance of physiological quality during
storage.
