Blackberry and raspberry seedlings growth under the soilless cultivation system

Abstract

The objective of this study was to evaluate the growth of micropropagated blueberry and raspberry seedlings under conventional and soilless cultivation systems. Seedlings of two blackberry cultivars (Xavante and Tupy) and two raspberry cultivars (Heritage and Fall Gold) were submitted to two cultivation systems: the conventional system and the soilless system. Under the conventional system, they were kept in polyethylene bags containing H. Decker® substrate and were irrigated with nutritive solution every 15 days. Under the soilless system, they remained in plastic flowerpots containing sand and were irrigated with nutritive solution daily. In regards to shoot length, the Xavante, Tupy, Heritage and Fall Gold cultivars showed the best results under the soilless cultivation system. As for number of lateral shoots, the Xavante, Heritage and Gold Fall showed significant results under the soilless system, unlike the cultivar Tupy, which showed better results under the conventional system. The soilless cultivation system is suitable for the development of the blackberry 'Xavante' and 'Tupy' and the raspberry 'Heritage' and 'Fall Gold' mini-cuttings

Recipientes, substratos e dias de cultivo no desenvolvimento de amoreira-preta ‘Xavante’

“…Para Silva (2017), em relação à mesma variável analisada, não houve efeito significativo ao comparar volumes de recipientes (5 e 9 litros) e substratos (fibra de coco e resíduo de uva S10-Beifort ® ) no cultivo de oliveira (Olea europaea L.) ornamental. Sommer et al (2016), verificaram resultados superiores no substrato comercial H. Decker ® em sacos de polietileno preto de tamanho 15x20 centímetros, no cultivo de amoreira-preta 'Xavante'. No que diz respeito a massa de matéria seca da raiz, houve interação entre os fatores substratos e volumes de recipiente, onde a fibra de coco e o recipiente com volume de 30 litros foi superior (Figura 5).…”
