To elucidate the physicochemical properties of Japanese native red-kerneled non-glutinous rice of the Japonica type cultivated without fertilizer application, a comparative study with 30 cultivars was...
Analysis of the Photosynthetic Characteristics of the High-Yielding Rice Cultivar Takanari
Apparent carboxylation efficiency Apparent quantum yield Chlorophyll content CO2 exchange rate
2009/7/23
It was clarified in a previous paper that higher dry matter production for a newly bred high-yielding rice cultivar, Takanari was mainly due to the higher net assimilation rate (NAR) owing to better l...
Comparison of Root Systems among Rice Cultivars by Simplified Investigation Methods
Cultivar difference Lodging tolerance Rice Root distribution Root profile Root projection area
