Studies on Culture of Cells and Tissues of Crop Plants:I. Survey on enzymatic isolation and culture of rice leaf sheath protoplasts
BSA Cell activity Cellulase "Onozuka" R-10 Protoplasts MS-medium Rice leaf sheath
2009/8/6
To establish a method for isolation and culture of rice protoplasts, enzyme solution compositions, culture conditions, and the selection of cultivars and tissues as materials were examined. The result...
Can Plants Normally Produce Seeds under Microgravity in Space?
Barley Gravity response Microgravity Mutant Seed production Seed fertility
2009/8/6
Growth analysis was performed on a barley (Hordeum vulgare L.) mutant line showing an abnormal gravity response, and also on the original normal line. The reproductive structures of mutant plants were...

Studies on the Dormancy-Awakening and -Breaking in the Two-Rowed Barley Seed:III. The dormancy-awakening of seeds obtained from plants affected by flooding and lodging during the ripening period
Dormancy-awakening Flooding Lodging Rachis positions Two-rowed barley
2009/8/4
Effects of flooding and lodging on the seed dormancy were studied in the two-rowed barley seed. Seeds were obtained from plants which were subject to the flooding treatment 4 times during the ripenin...
Floral Impotency Due to Cool Weather in Paddy Rice Plants in the Early-season Culture Area : III. Effect of growth retardant on the reduction of necessary water depth in the deep irrigation method at the booting stage
Antiauxin Cool-summer damage Growth retardant IBP Inabenfide Necessary water depth in deep irrigation method Paclobutrazol Uniconazole
2009/7/31
For the purpose of improving the deep irrigation method as a countermeasure of floral impotency due to cool weather by means of a reduction of the necessary water depth to protect young panicles, stu...
Relationship between Root Respiration and Silica : Calcium Ratio and Ammonium Concentration in Bleeding Sap from Stem in Rice Plants during the Ripening Stage
Ammonium Bleeding Calcium Rice Root respiration
2009/7/29
Rice plants were given various treatments, such as organic matter application, a large amount of nitrogen as topdressing and light shading of 75%, and ammonium (NH3), silica (SiO2) and calcium (Ca) in...
Effects of Scion and Stock on Root Growth of Grafting Plants between Two Potato Varieties with Different Root Mass
Dry matter partition Solanum tuberosum L

Acetylcholine as a Signaling System to Environmental Stimuli in Plants:I. Contribution of Ca2+ in heat-stressed Zea mays seedlings
AChE activity ACh response Ca2+ Heat stress Ion channels Zea mays
2009/7/27
Plant growth is influenced by transport of water, ions and hormones under various environmental stresses. If acetylcholine (ACh) mediates the opening and/or closing of ion channels in plants just as ...
Regularity in Variation of Leaf Color and Nitrogen Distribution in Half-Leaf Blades by Leaf Position on the Stems of Rice Plants:II. Uneven translocation of nitrogen between outside and inside half-leaves
Chlorophyll meter value Distribution Half-leaf blade Leaf blade width Nodal root Translocation
2009/7/27
We have reported in a previous paper that the outside half-leaf had a smaller volume and deeper leaf color than the inside half-leaf. The half-leaf color was not dependent only on the difference in le...
