Analysis of a high-yielding strawberry (Fragaria ×ananassa Duch.) cultivar 'Benihoppe' with focus on root dry matter and activity

Abstract

This study analyzes and clarifies the eco-physiological traits of high-yielding strawberry (Fragaria ×ananassa Duch.) 'Benihoppe' focusing on its dry matter production, total nitrogen content, bleeding rate, mineral nutrient concentration in bleeding fluid, and fine root respiration rate in comparison with those of the cultivar 'Sachinoka'. The results show that 'Benihoppe' has three beneficial characteristics. The first characteristic is higher primary and fine root dry matter and less root rotting during the cold season. The second is superior root function that includes high root activity and a well-maintained root system. The third is a high ability to absorb more NO3- and preferentially partition NO3- to the leaves, crowns, and fine roots. Thus, with these three beneficial functions, 'Benihoppe' may produce more dry matter and fruits than 'Sachinoka'. © 2014 The Japanese Society for Horticultural Science (JSHS), All right reserved.
