“…According to , the strawberry yield was the highest with the earliest independence of runner plants from mother plants, the nutrient supply was quickly discontinued, and the differentiation of the flower bud rapidly occurred. However, in the present study, the opposite results were obtained, which could be explained by different growth responses, growth characteristics, and amount of fertilizer depending on the cultivar (Choi et al, 2009;Choi et al, 2013). In addition, due to the inherent characteristics of strawberry genotypes, a wide variation in the flowering response was observed in different cultivars (Marcit et al, 2007;Rahman et al, 2014).…”

This study aimed to investigate the optimum supply period of nutrient solution for the growth of runner plants as well as the flowering, fruit quality, and yield of 'Maehyang' strawberry. The runner plants separated from the mother plants were divided into 5 groups, each receiving a supply period treatment of watering (W) and nutrient solution (N) [control (W40), combination of W and N: W20 + N20, W25 + N15, W30 + N10, and W35 + N5]. The EC and pH were 0.6 dS·m -1 and 6.5, respectively. The treated runner plants were transplanted to the strawberry growing pots filled with a commercial growing medium on September 13, 2017 and managed with EC 0.6 to 1.2 dS·m -1 strawberry nutrient solution. Growth characteristics and mineral elements of the runner plants were measured at 40 days after treatment. The crown diameter, fresh weight of shoot, and the leaf area were significantly higher in the W20 + N20 group. The P, Mg, S, and Fe contents in the runner plant leaves significantly increased in the W20 + N20 and the W25 + N15 groups. In addition, the C/N ratio was 7.81% higher in the W20 + N20 group than in groups that had received other treatments. The budding ratio and flowering of primary and secondary inflorescences in the W20 + N20 group were approximately 3 to 9 days faster compared to the control. The fruit characteristics, such as weight, length, diameter, firmness, soluble solids content, and acidity, were not significantly different across the groups. The total number of fruits and marketable fruit yield showed positive results in the W20 + N20 group during the total harvest period. The results indicate that the supply period of nutrient solution has a direct impact on the growth of runner plants of 'Maehyang' strawberry, and may also affect parameters of reproductive growth, such as flowering response and fruit yield after transplanting.Additional key words: budding ratio, C/N ratio, flowering response, marketable fruit Horticultural Science and Technology Extended Supplementation of Nutrient Solution for Runner Plant Production Improved the Growth of Runner Plants and Enhanced the ...

“…This occurs due to the reduction in the leaf blade area and, consequently, higher concentration of chlorophyll per unit of area (EPAMIG, 2007). Choi et al (2013) indicated that a deficient P nutrition causes retardation in the development of branches, reduction in stem elongation and a decrease in the capacity to withstand the weather, such as low or high temperatures, and the stress caused by pathogens. These authors, as well as Choi & Lee (2012), also show that the excess of P in strawberry tissues reduces the size of shoots, favors the yellowing of leaves and decreases the contents of Fe and Zn in plant tissue.…”

A B S T R A C T Strawberry (Fragaria x ananassa)is a crop that has rapid growth and is highly influenced by fertilization. Due to its development speed, the plant needs to absorb sufficient macronutrients in order to meet its demand. The objective of this research was to evaluate growth and yield of strawberry under different doses of nitrogen (N), phosphorus (P) and potassium (K) fertilization. The treatments, using Box's central composite design, were distributed in randomized blocks with four replicates and consisted of five N doses (0.16, 0.37, 0.88, 1.4 and 1.6 g plant ) and absence of K. Seedlings of the cultivar 'Oso Grande' were cultivated in 10-L pots. The analysed variables were: plant height, fresh fruit mass, number of leaves, number of fruits, total soluble solids and titratable acidity. The fertilization with N and P increased the values for most of the studied variables. At the highest doses of N and P, K stimulated plant yield.Crescimento e produção de morangueiro adubado com nitrogênio e fósforo R E S U M O O morangueiro (Fragaria x ananassa) é uma cultura que apresenta rápido crescimento, além de ser bastante influenciada pela adubação motivo pelo qual é notória a necessidade de absorção suficiente de macronutrientes a fim de atender às demandas da planta. Propôs, neste experimento, avaliar o crescimento e a produção do morangueiro em função da adubação com nitrogênio e fósforo na ausência e na presença de potássio. Os tratamentos em que foi utilizada a Matriz Composto Central de Box foram arranjados em blocos ao acaso com quatro repetições. Foram avaliadas cinco doses de nitrogênio (0,16; 0,37; 0,88; 1,4 e 1,6 g planta ) e na ausência de potássio. As mudas utilizadas foram do cultivar Oso Grande cultivadas em vasos de 10 L; as variáveis analisadas foram: altura das plantas; massa da matéria fresca dos frutos, número de folhas, número de frutos; sólidos solúveis totais e acidez titulável. A adubação com nitrogênio e fósforo aumentou os valores na maioria das variáveis estudadas enquanto nas maiores doses de nitrogênio e fósforo o potássio estimulou o rendimento das plantas.

“…strawberry, which has a higher absorption capacity for monovalent cations than 'Redpearl', which in turn, has a unique absorption characteristic that changes the pH of the root zone to strong acidic and is an important cause of soil Ca deficiency (Choi et al, 2013). Lee et al (2015) reported that the pH in the root system was significantly lowered by the acidity of the fertilizer used on the plants, and the amount of absorption of Ca and Mg decreased.…”

The causes of tipburn were studied on the leaves of the two strawberry cultivars 'Seolhyang' and 'Red pearl' that were grown either in soilless culture medium or in soil during 2010-2012. The Ca, Mg and K content in leaves, petiole and guttated fluids were analyzed and induction of tipburn in detached leaves was determined. During the 3-year observation, there were hardly any tipburn affected plants when grown in soil, whereas plants grown in soilless culture medium showed different sensitivity depending on the year. Analysis of discrete area of leaves, petiole sap and guttated fluid indicated the importance of Ca nutrition, although the absolute concentration of Ca may not be a crucial factor in tipburn induction. Use of detached leaves confirmed that Ca uptake and transport by positive xylem pressure are deciding factors for the occurrence of tipburn.
