Development and fruit yield of strawberry plants as affected by crown diameter and plantlet growing period

Abstract

-The objective of this work was to evaluate the influence of crown diameter and growing period of runner tips in 128 cell-trays on growth and yield of strawberry in the field. Treatments consisted of three classes of runner tip crown diameters, between 2.0 to 3.9 mm; 4.0 to 5.5 mm and 5.6 to 7.0 mm, respectively, and four growing periods in trays, 24; 39; 54 and 69 days, respectively. Higher shoot dry mass of transplants at planting and earlier yield of plants in the field were obtained in transplants grown for 69 days in trays. Larger runner tips lead to more vigorous transplants at planting and plants with higher vegetative growth in the field, with minor impact on yield. Increasing the growing time of runner tips in trays improved early fruit yield and decreased plant vegetative growth in the field.Index terms: Fragaria x ananassa, early yield, propagation, plug plants. Desenvolvimento e produtividade do morangueiro influenciados pelo diâmetro da coroa e período de crescimento de mudasResumo -O objetivo deste trabalho foi avaliar a influência do diâmetro das pontas de estolão e do seu período de crescimento em bandejas sobre o crescimento da planta e produtividade do morangueiro Arazá. Os tratamentos consistiram em três classes de diâmetro das pontas de estolão: entre 2,0 e 3,9 mm; 4,0 e 5,5 mm e 5,6 e 7,0 mm, e quatro períodos de crescimento nas bandejas: 24; 39; 54 e 69 dias. Maior massa seca vegetativa das mudas no plantio e maior produção precoce das plantas foram obtidas com mudas que cresceram 69 dias nas bandejas. Pontas de estolão de maior diâmetro originaram mudas mais vigorosas no plantio e plantas com maior crescimento vegetativo no campo, sem efeito na produtividade de frutas. O aumento do período de crescimento das mudas nas bandejas aumentou a produção precoce de frutas e diminuiu o crescimento vegetativo das plantas no campo.Termos para indexação: Fragaria x ananassa, precocidade, propagação, muda com torrão.

Influence of Different Nutrient Concentration on Strawberry under Hydroponic Cultivation System

“…The number of leaves depends on the time of transplanting and the runner tips. If runners will less that number of leaves will also become less in plants (Carine et al, 2010). At 60 days leaf/plant observation shows the 4.78 % increase in the leaf/plant; however the variation in treatment are 10-14 and treatment T 6 shows the best impact on the leaf/plant.…”

Influence of the quality of mother plants on selected parameters of Fragaria x ananassa ‘Elsanta’ daughter plants

“…The highest number of leaves is observed for daughter plants produced by mother plants established from fresh-dug plants. 2. The initial size of mother plants significantly influences the fresh and dry weight of daughter plants.…”

“…Results of many studies show that low quality of transplants is the main limiting factor of strawberry crops [1,2]. A number of components have influenced strawberry yield, including type of planting material [3][4][5], crown diameter [2,6], initial plant weight [3,7,8], and number of leaves [9].…”
