Correlation between selected parameters of planting material and strawberry yield

Abstract

The aim of this study was to determine the effect of fresh and dry weight, as well as the number and length of roots and number of crowns of different types of plants, on the yield of strawberry grown for the spring and autumn harvests. Three different types of frigo strawberry plants (waiting bed plants, plug plants, A+ plants) and two strawberry cultivars ('Honeoye' and 'Elsanta') were compared in the experiment. The plants were grown in polypropylene bags in an unheated glasshouse in the years 2002-2005. The correlation coefficients were calculated to estimate the relationship of the strawberry plants' parameters to the yield quantity. An analysis of regression for the plant parameters that most significantly correlated to the strawberry yield was carried out, which determined that the fresh and dry weight of the strawberry plants, crown number, as well as length of roots were positively correlated to the quantity of the strawberry yield. The highest positive correlation coefficient was found for the fresh weight of a whole plant and the lowest one for the number of roots.

Carbohydrate Content and Development of Strawberry Transplants From Rio Grande Do Sul and Imported

“…As expected, Chilean transplants with higher crown diameter and reserve content showed higher precocious and total yield. Bartczak et al (2010) reported that the use of poor-quality transplants can lead to a drop in production, which is impossible to recover through management techniques during the crop cycle. Thus, although early planting positively influences leaf emission and root system growth, is not able to ensure high yield compared to those originally characterized as low physiological quality.…”

“…These physiological processes are dependent on the accumulated reserves until the plant acquires autonomy in energy production and supply (BARTCZAK et al, 2010). Thus, the greater the amount of carbohydrates accumulated during summer and autumn, the greater the productive potential of transplants, especially for the early production of fruits (SONSTEBY et al, 2013;TORRES-QUEZADA et al, 2015).…”

“…During summer, high temperatures and long photoperiod are the climatic conditions that stimulate the vegetative propagation of strawberry tree through the emission of stolons (BRADFORD et al, 2010). At the end of the summer and beginning of autumn, the reduction of temperatures and photoperiod favors the accumulation of carbohydrates in reserve organs, resulting in increased thickness of crown and roots (PERTUZé et al, 2006;MENZEL;SMITh, 2012).…”

Vegetative Stage of Strawberry Duration Determined by the Crop Year

“…Other factors like genotype (RAHMAN et al, 2016), initial weight of the plant (BARTCZAK et al, 2010), number of leaves (COSTA et al, 2014) and application of fertilizers (LOVAISA et al, 2015) can also influence the phenological development of the plant.…”

Effect of plant type and delayed planting on growth and yield parameters of two short day strawberry (Fragaria x ananassa Duch.) cultivars in open field

“…The quality of transplants used for establishment of grower's field is of high importance [1,2]. In Norway, until year 2015, when the borders were opened for import of strawberry plants, transplants had to be propagated in Norway under a strict control regime to avoid virus, pest and disease infection of plants.…”
