杂草稻是田间的“山寨版”水稻,直接导致稻田减产,品质下降。浙江大学联合中国水稻研究所的科研人员通过基因组重测序及分析,揭示了杂草稻的遗传机制,为杂草稻防治奠定理论基础。相关论文日前在线发表在《自然·通讯》杂志上。“杂草稻出现在田间,与正常的栽培水稻争阳光、水和养分,严重影响着水稻产量与品质。杂草稻米粒口感坚硬粗糙,如果农民在收割时混入了杂草稻,大米就卖不出好价钱。”浙江大学农业与生物技术学院作物科学研究所教授樊龙江说。
Weedy rice is a field “cottage version” of rice, a direct result of reduced production of rice, the quality decline. Researchers at Zhejiang University's Joint China Rice Research Institute revealed the genetic mechanism of weedy rice through genome resequencing and analysis, laying a theoretical foundation for the prevention and treatment of weedy rice. Related papers recently published online in the “Nature · Communications” magazine. “Weedy rice appears in the field and competes with the normal cultivated rice for sunshine, water and nutrients, which seriously affect the yield and quality of rice. The weedy rice grain has a hard and rough texture. If farmers mix with weedy rice during harvesting, rice Can not sell a good price. ”" Zhejiang University College of Agriculture and Biotechnology Institute of Crop Sciences, said Fan Longjiang.
