The Effect of Seed Size on Germination and Seedling Growth in Sweet Chestnut (Castanea sativa Mill.)

The quantity and quality of seedlings in the nursery has an impact on success re-establishment later growth. High germination rates enable a sufficient number seedlings, their is assessed using parameters, including seedling height root collar diameter. These parameters are influenced some species by seed size, but correlation between them species-specific. model this research was sweet chestnut (Castaneasativa Mill.), seeds from 12 populations two distinct biogeographical regions Croatia were collected. We examined influence size four parameters: rate, height, diameter sturdiness quotient. Seed been shown to have positive both diameter, whereas no such noted for rate Significant differences nut growth found Mediterranean continental populations, with higher values observed coastal populations. concluded that origin significant important factors consider when choosing material.
