ABSTRACT

Experiments were conducted to examine the effect of time of planting on the performance of ‘Albion’ and ‘Camarosa’ strawberry plants in a greenhouse in Brazil. New transplants were planted in March, April, May or June in the first year, and in March, April or May in the second year. Information was collected on crown production, leaf area expansion, shoot dry weight, marketable yield and average fruit fresh weight. Vegetative growth and marketable yields were higher in ‘Camarosa’ than in ‘Albion’, while the reverse was true for average fruit fresh weight. The number of crowns/plant, leaf area/plant and shoot dry weight generally decreased as planting was delayed. Yields were highly variable with no clear pattern across years, except for lower yields with the plantings in June. Mean yields (± SE) were 766 ± 72 g/plant for March, 876 ± 135 g/plant for April, 723 ± 169 g/plant for May and 533 ± 209 g/plant for June. Average fruit fresh weight decreased as yield increased and was lower in the earlier plantings. The results of these experiments suggest that the new transplants can be planted from March to May for commercial production in this area.

摘要

进行了实验以检查种植时间对巴西温室中“Albion”和“Camarosa”草莓植物性能的影响。第一年的三月、四月、五月或六月种植新的移植物，第二年的三月、四月或五月种植新的移植物。收集了有关树冠产量、叶面积扩大、枝条干重、可销售产量和平均果实鲜重的信息。'Camarosa' 的植物生长和可销售产量高于'Albion'，而平均水果鲜重则相反。树冠/株数、叶面积/株数和枝条干重通常随着种植延迟而减少。除了 6 月份播种的单产较低外，不同年份的单产变化很大，没有明确的模式。3 月份的平均产量 (± SE) 为 766 ± 72 g/株，4 月为 876 ± 135 克/株，5 月为 723 ± 169 克/株，6 月为 533 ± 209 克/株。平均水果鲜重随着产量的增加而下降，并且在较早的种植中较低。这些实验的结果表明，新的移植物可以在 3 月至 5 月种植，用于该地区的商业生产。
