Abstract
: Hop cones are an indispensable raw material used for beer brewing. Since the hop plant is a minor crop, expansion habit of the hop root system has not been well investigated. In this study, we observed and analyzed the root systems of two major hop cultivars in Hokkaido, Little Star and Furano Special, using the wall profile method and root depth index. The results suggest differences in expansion habit of the hop root between the two hop cultivars, which has not been reported previously. The results also indicate that the different responses in cone yield to precipitation between the two hop cultivars may be derived from their differences in root expansion habit. The results of this preliminary study support the view that a better understanding of the hop root system could lead to improved productivity of hops via the development of agronomical techniques or genotypes.
期刊介绍:
Plant Root publishes original papers, either theoretical or experimental, that provide novel insights into plant roots. The Journal’s subjects include, but are not restricted to, anatomy and morphology, cellular and molecular biology, biochemistry, physiology, interactions with soil, mineral nutrients, water, symbionts and pathogens, food culture, together with ecological, genetic and methodological aspects related to plant roots and rhizosphere. Work at any scale, from the molecular to the community level, is welcomed.
