Estimation of Leaf Area Index in Crop Canopies using Plant Canopy Analyzer.
Plant length, tiller number and nitrogen content of rice plant (Oryza sativa L. cv. Koshihikari) having produced five different levels of spikelet numbers were computed by averaging data obtained in ...
Adaptive changes were studied comparatively in soybean and cotton grown in pots under four irrigation conditions i.e. normal irrigation (equal to the evapotranspiration of the crop), and 50%, 25% and ...
Exploring approaches to optimizing spatial distributions of leaf area index (LAI) and leaf nitrogen content (LNC) should be useful for increasing grain yield in rice (Oryza sativa). The primary object...
Estimation of Leaf Area Index in Rice Canopy by Tube Solarimeter and Photodiode.
To examine the possibility of breeding high-yielding cultivars with high nitrogen use efficiency for dry matter accumulation (NUEd) and to provide simple criteria for the selecting and breeding high-y...
To clarify the high yielding characteristics of new rice varieties recently bred in the cold region of Japan, we examined their yielding ability, yield component and harvest index in 1996 (24 varietie...
To find useful indexes for the selection of new rice varieties having a high harvest index, the correlation of harvest index (HI) with morphological characteristics and leaf color was examined using 6...
Varietal differences harvest index (HI) and yield (Y) were examined using 60 Japanese varieties (J group) and 20 high-yielding varieties bred in Asian countries (H group). HI varied from 36.8% to 53.4...
A wheat cultivar "Haruyutaka" bred in Hokkaido has a small harvest index, grain weight and yield when it grows in Yamaguchi, Japan. Ethephon, a growth regulator, applied to the surface of wheat canopy...
A wheat cultivar, "Haruyutaka", bred in Hokkaido, was planted and examined at nine cultivation conditions of the four seasons, 1995/1996 to 1998/1999, in Yamaguchi, Japan, for the purpose of introduci...
In order to evaluate the usefulness of several physicochemical properties for selecting rice cultivars with high palatability, we analyzed the relationship between the palatability and the physicoche...
The seeding date and heading date (HD) in direct seeding cultivation under a submerged soil condition were examined with three rice varieties at 27-40 sites of Hokkaido in 1999-2003. The effective th...
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...
The flesh firmness of sliced tomato (Solanum lycopersicum L. ‘Reiyo’), cultivated under two different nutrient control systems with various amounts of supplied nutrients, was evaluated by acoustic vib...
