Effects of reduced plant height on breeding requirements and ...

tÌ'rerase 1ve s we!ìe generally positive" The positåve relation-
ship <strong>of</strong> barley nitrogen and saccharifying activity was
previously reported by Metcaife, et åL. e96?). Rutger
et a1. (196?) reported a posi-tive correlatíon between
saccharifying aetivity and level_s <strong>of</strong> alpha-aroylase.
A signifieant negative relationship existed bet$,een
alphra-amylase and percent barley nitrogen in population
Ç-7O-3, while in the other populations no relationship was
found" Hayter and Riggs (fg?3) reported no association
between these characteristics ín their experíment"
Analyses <strong>of</strong> 'uariance (ANOV¡, ) were computed to determine
the significance <strong>of</strong> effects <strong>of</strong> rates <strong>of</strong> nítrogen (N)
