This study is intended to measure variations of nutritional soil condition and mass spectrometric patterns to describe the specific effects of electric pulse charged to culture soil which induced an i...
Relationship between Seedling Emergence Rate and Embryo Weight of Rice under Low-Temperature and Submerged Soil Condition
Direct seeding cultivation Embryo weight Low temperature Rice Seedling emergence coefficient
2009/7/21
Rapid seed germination and higher seedling emergence under low-temperature and submerged soil conditions are desirable to stabilize the direct seeding cultivation of rice in temperate regions. This st...
A New Method of Evaluating Seedling Emergence Rate in Direct Seeding under Submerged Soil Condition, and New Gene Sources of Seedling Emergence
Gene source Evaluating method Rice Direct seeding Tape seeder Seedling emergence
2009/7/9
We previously reported a method of screening seed with a high seedling emergence rate in which seeds were sown 20 mm deep from the soil surface at 25°C in a growth chamber. In this paper, we propose ...
Studies on Evaluating Method and Genetic Variation of Seedling Emergence in Direct Seeding under Submerged Soil Condition
Gene stock Evaluating method Seedling emergence Rice Direct seeding Submerged soil condition
2009/7/9
The seedling emergence of rice in direct seeding in submerged soil was investigated with respect to the degree of the forced sprouting, temperature and seedling depth. As a preliminary test, eight re...
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 ...
Selection of Rice Varieties Suitable for Direct Seeding under a Submerged Soil Condition by Using the Effective Thermal Index in Hokkaido, in Northern Japan
Cumulative air temperature Effective thermal index Grain-filling period Submerged direct-seeding
2009/7/8
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...
Grain Yield and Palatability of Rice Direct-seeded under Submerged Soil Condition in Hokkaido, in Northern Japan
Amylose content Direct seeding under submerged soil condition Grain yield Harvest index Protein content
2009/7/7
Grain Yield (GY), its components and palatability of rice direct-seeded under a submerged soil condition (direct-seeded rice, DSR) were compared with those of transplanted rice (TR) applying a simila...
