Response of seed size, storage condition, media and sowing time on seed germination and subsequent growth of chestnut (Castanea sativa Mill) seedling

Significantly higher seed germination (48.67%), seedling height (28.83cm), seedling diameter, number of laterals, and length and diameter of laterals were recorded in extra large seed of chestnut (Castanea sativa Mill). Although seed stored in aluminum foil pouch exhibited maximum germination per cent (47.75%), the maximum seedling growth was registered in sand storage condition. Large seeds stored in sand and aluminum foil pouch resulted in good germination and seedling growth. Significantly maximum seed germination (33.5%) was registered in soil + sand (media), whereas other growth parameter was highest in field sown seedling. November sown seeds resulted in maximum germination (45.5%) and seedling height; however, seedling diameter, number of laterals and diameter were highest in October sown seedling. Large seed and November sowing had highest germination (52.70%). Field sowing in month of November resulted in maximum seedling height and diameter, length of laterals and their diameter.
