Abstract

Three experiments were conducted during the years of 2001 and 2002, to investigate the effects of seed priming on pepper seed (1) germination in the laboratory, (2) seedling growth under nursery conditions, (3) how long primed seed can be stored before planting and still maintain the advantage achieved from priming, and (4) the possibility to improve germination by priming seed harvested at different fruit maturity levels. These experiments were conducted with locally­produced seeds of pepper (cv California Wonder) at Mansoura Horticultural Research Station, Baramoon Farm and Mansoura Seed Technology Unit, Agriculture Research Centre, Ministry of Agriculture, Egypt. Under the conditions of these experiments, it may be concluded that: 1. Seed priming agents have promotional effects on pepper seed germination and seedling establishment. 2. Using PEG or KNO3 as priming agents give the best germination behavior and seedling growth. 3. Storing primed pepper seeds for up to 9 months can maintain the benefits acquired by seed priming, especially if priming solutions used are PEG, KNO3 or mannitol. Some harmful effects appear if KCl is used as priming agent, so its use should be avoided. 4. Seed priming, especially in K2HPO4 solution, can markedly increase germination of seeds extracted from fruits harvested at 30 or 45 dpa. However, it is better to wait until 60 days dpa to harvest the fruits. GENERAL EVALUATION Seed priming can create and open new research and crop production windows in seed technology under Egyptian conditions
