| Özet |
| The success of any sustainable reforestation program, among other things, hinges on a continuous supply of high quality seeds for the production of the desired quantity of seedlings in nurseries or for successful stand establishment by direct sowing out in the field. What is seed quality then? Seed quality is defined as “a measure of characters or attributes that will determine the performance of seeds when sown or stored”(Hampton 2002). It is a multiple concept encompassing the physical, physiological, genetic, pathological and entomological attributes that affect seed lot performance (Basu, 1995).Several factors affect the production of high quality seeds, such as insect infestation (El Atta 1993, Dajoz 2000, Bates et al. 2000, 2001), pollination failure and post-zygotic degeneration (Owens et al. 1990, El-Kassaby et al. 1993), infection by seed borne pathogens (Pritam and Singh 1997), environmental conditions during seed development (Gutterman 2000) as well as the genetic constitution (Bazzaz et al. 2000). |
