ABSTRACTAccurate estimation of sink capacity in rice (grain number × potential grain size), independent of grain filling, is necessary for considering source – sink interactions. However, how to measure potential grain size is still a matter of de

Rice growth at an elevated air temperature (Tair) during the ripening period is often evaluated using a semi-closed chamber (SCC). However, the water vapor pressure deficit (VPD) and CO2 concentration inside SCCs get lower than at ambient air plot, a

A new rice (Oryza sativa L.) cultivar, ‘Oonari’, was developed to reduce the shattering habit of the high-yielding cultivar ‘Takanari’. To evaluate the effects of environment on its yield and related traits, Oonari and Takanari were grown in

The relay intercropping system for cultivating direct-seeding rice and winter cereal is a low-cost method particularly for double cropping, because it eliminates the steps of raising seedlings, paddling, and transplanting. However, in this system, th

Tachisuzuka, a rice cultivar for whole-crop silage, is characterized by a small panicle and high sugar content in the stem. Our previous study suggests that the high sugar content in the stem of Tachisuzuka is due to a factor other than the small pan
