Root Growth and Distribution in Some Japonica-Indica Hybrid and Japonica Type Rice Cultivars under Field Conditions
High-yielding rice cultivars Oryza sativa L Rice Root length density Root system Root weight density
2009/7/30
The development of rice root system has been studied in Japonica-Indica hybrid cultivars (J-IH), Milyang 23 and Suweon 264, and Japonica type cultivars (JT), Nipponbare and Koshihikari, grown in a pad...
Effect of Dark Respiration on Dry Matter Production of Field-Grown Rice Cultivars:Growth efficiency of early, medium, and late-maturing cultivars
Dark respiration rate Dry matter production Earliness of cultivar Growth efficiency Rice
2009/7/15
The dry matter production, dark respiration rate, and growth efficiency of early-(Koshihikari), medium-(Nipponbare)and late-(Akebono)maturing rice cultivars, were examined. The yield was lowest in Kos...
Evaluation of Various Screening Systems for High Grain Quality in Rice Cultivars under High-Temperature Grain-Filling Conditions, and the Selection of their Standard Cultivars
Grain quality High temperature tolerance Oryza sativa L Rice Standard variety
2009/7/8
Opaque grain caused by high temperatures at the ripening stage is a major constraint for the commercial production of rice. I evaluated the selection methods for the breeding of high temperature-tole...
Studies on the in vitro Starch Digestibility and the Glycemic Index in Rice Cultivars Differing in Amylose Content
Amylose Glycemic index Non-digestible oligo saccharide Rice Starch hydrolysis
2009/7/8
Starch digestibility was studied in eight rice cultivars with four levels of amylose content.An in vitro digestion method with α-amylase was applied to estimate the glycemic index in vivo based on ki...
