北海道大学 作物学研究室
北海道大学農学部 作物学研究室は，人類の主要な食用作物を対象にして，圃場における生産性に関する理論的・実証的な研究を行なっています．作物学研究室のポリシーは，「研究のための研究」だけではなく，圃場で自ら作物を栽培して実験を行い，得られた情報を農業現場へフィードバックすることにあります．私達は，世界の食糧生産，そして地域農業に貢献する研究として，作物の環境ストレス抵抗性改善に関する研究を行っています．
Research
Our main objective is to improve the agricultural productivities on major food crops cultivated in the fields under abiotic stresses, such as drought, cool weather damage etc.. We are focusing on the topics which concern with the relations between the environmental factors and the morphogenesis, photosynthetic production, remobilization of plants under the field conditions. These studies will advance the fundamental theories of agricultural sciences.
Research Topics
Drought tolerance improvements in wheat
Due to the global warming, most of the major wheat cultivation regions are jeopardized by droughts. Our laboratory is studying on the relevant morphological/physiological traits,
e.g. root systems, canopy photosynthesis, ear photosynthesis etc. through field based biometric techniques to improve the wheat drought tolerance.
High-yielding Hokkaido rice varieties for high latitude and cool environments
We are studying the relevant characteristics through which the rice productivity can be improved in the high latitude and cold regions. The rice productivity improvements in such regions would have great impact for the global food security as the photoperiod sensitivity
and narrow cultivation window have been serious constraints.
We are providing valuable agronomic information for moving forwards high the yielding rice breeding through interacting with the rice research institutes.
Productivity improvements on C4 photosynthesis crops under cool environments
The maize as C4 crop is well adapted to tropical arid environments. In Hokkaido with cooler environments, it is great challenge to improve the productivity. We investigate the agronomic as well a physiological mechanism through which the productivity improvements can be achieved.
Sustainable Agriculture and Environments
In addition to the abiotic stress improvement studies, we are studying the mitigation of abiotic stress itself through sustainable agriculture systems. On the low input sustainable agricultural platform, the comprehensive studies for crops productivity improvements are being pursued.
