Male Sterility Caused by Cooling Treatment at the Young Microspore Stage in Rice Plants:XXX. Relation between fertilization and the number of engorged pollen grains among spikelets cooled at different pollen developmental stages
Anther Cool injury Cool temperature Microspore Pollen Rice Sterility
2009/8/6
Cooling treatments at different stages of pollen development lowered the percentage of fertilized spikelets through decreasing the number of engorged pollen grains per anther at anthesis. Cooling duri...
Partitioning of 15N Applied at Reproductive Stages among Grains and in Grain Tissues of Rice Plants
Competition Grain Nitrogen Partitioning Position on panicle Rice Ripening
2009/8/4
Hydroponically-grown rice (Oryza sativa L.) plants were pulse-labelled with 15N-ammonium sulphate at various stages of reproductive growth, and partitioning of 15N among grains or grain tissues were e...
Distribution and Connection of Vascular Bundles in Relation to the Accumulation of Starch Grains in the Potato Tuber
Assimilate Phloem Potato Starch Translocation Tuber Vascular bundle
2009/8/4
By making serial sections, the distribution and connection of vascular bundles in the potato tubers were observed by light microscope. The vascular bundles entered from stolon into the rose end of tub...
Variation of 2-Acetyl-1-Pyrroline Concentration in Aromatic Rice Grains Collected in the Same Region in Japan and Factors Affecting Its Concentration
Aromatic rice Harvest time Oryza sativa L 2-Acetyl-1-pyrroline Temperature Variation
2009/7/28
Aroma strength of aromatic rice varies with the genetic and environmental conditions. We determined the concentration of 2-acetyl-1-pyrroline (2AP), a key compound of the aroma of aromatic rice, in 62...
Effects of Soil Types and Fertilizer Application on Mineral Contents of Wheat Grains and Flour : I. The relationship between ash content and mineral contents of grains and flour
Ash Calcium Magnesium Manganese Phosphorus Potassium Siol type
2009/7/24
Grain and flour of Asakazekomugi and Norin 61 cultivated in Gray lowland soil, Red soil and Thick High-humic Andosol were analyzed for N, P, K, Mg, Ca and Mn contents. Ash content was compared with t...
Influence of Low/High Temperature on Water Status in Developing and Maturing Rice Grains
Kernel Low/high temperature Maturation NMR relaxation times (T1 and T2) Rice Water status
2009/7/24
Temperature limits productivity and kernel quality of rice grains. Water status of rice (Oryza sativa L. cv. Hinohikari) grains grown at 20, 25 and 30°C was evaluated by NMR relaxation times (T1 and T...
The Influence of Temperature during Grain-Filling and the Location of Grains within Rice Panicle on the Amylose Content of Rice Variety "Kirara 397"
Amylose content Transplanting time Seedling age Primary branch Kirara397
2009/7/7
The factors affecting amylose content of the rice variety "Kirara 397" were analyzed. Temperature during grain filling, planting year, kind of seedling, heading date, and the location of grains on pa...
In this study, pollen grains were sampled by using a Lanzoni trap (Lanzoni VPPS 2000) in atmosphere of Bursa in 1999 and 2000. During two years, a total of 13,991 pollen grains/m3 which belonged to 59...
