Abstract:The container nursery experiment was conducted with ‘Qinglin ’ walnut ( Juglans regia L.) seeds in greenhouse to study the emergence rule and growth process of seedlings .The results showed that the germination rate of ‘Qinglin’ walnut seeds was 97.0%, and the emergence rate of seedlings was 90.3%.The seedlings grew uniformly , and the seeding time was shorter .The growth of ‘Qinglin’ walnut seedlings passed through four consecutive phases including seedling emergence period , young period , fast -growing period , and hardening period .Two fast -growing periods of annual walnut seedlings appeared in plant height and ground diameter;the first one was from the last ten -day of March to the first ten-day of April;the second one for plant height was from the middle ten -day of July to that of August , while that for ground diameter was from the first to the last ten-day of August .The change of plant height and ground diameter could be well de-scribed by the typical “S” curve.For the annual walnut seedlings , the ratio of dry weight to fresh weight was 0 .494;the ratio of fresh weight between the overground part and underground part was 1 .072 , while that of dry weight was 0.915.
