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.

基于壁形法的啤酒花根系定量评价
啤酒花锥是酿造啤酒不可缺少的原料。由于啤酒花是一种小型作物,对啤酒花根系的生长习性还没有很好的研究。本研究采用壁型法和根深指数对北海道两个主要啤酒花品种小星和富良野的根系进行了观察和分析。结果表明,两个啤酒花品种之间的啤酒花根扩张习性存在差异,这在以前没有报道过。结果还表明,两种啤酒花品种的球果产量对降水的不同响应可能源于它们根系扩张习性的差异。这项初步研究的结果支持这样一种观点,即更好地了解啤酒花根系可以通过发展农艺技术或基因型来提高啤酒花的生产力。
