Performance of green pepper seeds covered with different materials

The technique of covering seeds has been used mainly for the species which have small seeds, such as vegetables, forage, forest and ornamental species, because besides increasing the size of the seeds for direct sowing, it is possible to add other elements which are necessary for the good development of the plant in its early stages. In this context the objective of the present study was to covered green-pepper seeds in different types of materials and to evaluate their behavior during storage. Seeds treated and not treated with Rovrin at the dosage of 200g/100kg were submitted to pre-conditioning for the imbibing of seeds in KNO3 in -1,1Mpa solution, in an aired system for 5 days. After drying the seeds were covered in a mixture of sand + microcellulose and another of limestone + microcellulose. The covered seeds and those not covered were dried and packed in paper envelopes (permeable pack) and in aluminum envelopes (impermeable pack) and stored at room temperature in the Seeds Analysis Laboratory at UFLA. The seed quality was evaluated once every four months, for a period of 20 months, using the following parameters: water content, germination test, accelerated aging, controlled deterioration and emergency in soil + sand. From the results, it was possible to conclude that the covering of seeds slows but does not affect the germination rate of the green pepper seeds before storage, but the covered seeds deteriorate faster than the seeds not covered, when stored in permeable packs. The nature of the materials used did not affect the quality of the green pepper seeds stored in impermeable packs.
