Accelerating maturity in Picea seedlings


, : Accelerating maturity in Picea seedlings. Acta Horticulturae (56): 105-114

When several species and hybrids of Picea were grown from seed under a 24-hour photoperiod with optimum temp., moisture and nutrients, they did not enter dormancy but showed a continuous and vigorous free growth. This 'accelerated-optimal-growth' treatment shortened the juvenile period and promoted precocious flowering after planting out. Treated seedlings of P. glauca were planted out younger, and showed a more rapid growth rate after planting out, than seedlings raised in a nursery.
