Characteristics of Rooting and Leaf Emergence Rate, Early Growth and Heading Date of Rice Seedlings with Different Plant Age in Leaf Number
Early growth Heading date Leaf emergence rate Rice plant Rooting Seedling age in leaf number
2009/7/29
Eleven kinds of rice seedlings with different plant age in leaf unmber in the range 0-7.2 (counting the incomplete leaf as the first leaf), raised under the same condition, were grown in the phytotron...
Varietal Differences in Germination Rate, Storability, and Flooding Tolerance of Soybean Seeds Produced from Different Cultural Seasons and Locations
Cultural season Germination Locality Seed flooding tolerance Soybean Storability Varietal difference
2009/7/27
Seed germination rate, storability, and flooding tolerance are important factors involved in soybean production in high-temperature and excessive-moisture areas. To evaluate the effects of environment...
Relationship between Export Rate of Photoassimilates and Activation State of Sucrose Phosphate Synthase in Submerged Floating Rice
Export rate of photoassimilates Floating rice Sucrose phosphate synthase
2009/7/23
Floating rice (Oryza sativa L.) responds to submergence by rapid internodal elongation. This stimulated growth needs an increase in the supply of photoassimilates. We investigated the effects of subm...
Effect of Time and Rate of Nitrogen Application on Root Growth with Special Reference to Chinese F1-hibrid Rice "Shanyou 63"
F1-hybrid rice Number of crown root primordia Number of crown roots
2009/7/23
The effect of time and rate of nitrogen application on root growth and their relations with constituents of top per hill were investigated using Chinese F1 hybrid rice (cv. Shanyou 63) under water cul...
Bleeding Rate of Field-Grown Maize with Reference to Root System Development
Bleeding rate Diurnal change Maize Nodal root Root Root system
2009/7/15
Bleeding rate could be an effective index for the physiological activity of a whole root system in field-grown crops, because it is based on active water absorption caused by root pressure. We examine...
Growth, Leaf Photosynthetic Rate and Leaf Chemical Composition in Two Genotypes of Kenaf (Hibiscus cannabinus L.)
Yuefeng Morphological characters Kenaf Fiber crop
2009/7/9
Two genotypes of kenaf (Hibiscus cannabinus L. : cv. Yuefeng 1 and a National Agriculture Research Center (NARC) strain) were cultivated in 1999 and 2001 to determine and compare growth and morpholog...
Breeding of Rice for a High Seedling Emergence Rate in Direct Seeding under a Submerged Soil Condition
Direct Seeding Evaluation Method Gene Source Rice Seedling Emergence
2009/7/9
Rice lines with a high seedling emergence rate were screened by sowing the seed 20 or 30 mm deep from the soil surface at 20°C or 25°C in a growth chamber, or placing the seeder-tape 20 mm deep from ...
Factors Affecting the Bleeding Rate from the Basal Part Cut End of Stem in Soybean (Glycine max (L.) Merr.) Seedlings
Bleeding rate Glycine max (L.) Merr Respiration rate Root physiological activity
2009/7/9
The bleeding rate from the stem cut end is considered to reflect the root physiological activity since the bleeding is caused by the active water absorption by root. We analyzed factors affecting the ...
Reduction of the Occurrence Rate of Soybean Dwarf Disease by Late Seeding
Foxglove aphid Late seeded soybean production Soybean Soybean dwarf disease Yukihomare
2009/7/8
To investigate the effect of late seeding on occurrence of soybean dwarf disease (SbD) in soybean (Glycine max (L.) Merr. Cv. Yukihomare), we conducted two field experiments at the National Agricultur...
Correlation and Regressive Model Between Spikelet Fertilized Rate and Temperature in Inter-Subspecific Hybrid Rice
fertilization inter-subspecific hybrid rice regression temperature
2008/12/11
o study the sensitivity of inter-subspecific hybrid rice to climatic conditions, the spikelet fertilized rate (SFR) of four types of rice including indica-japonica hybrid, intermediate hybrid, indica ...
