Grain shape is a key trait in rice breeding. Although many QTLs and genes of grain shape have been identified, how different combinations of alleles of these genes affect grain shape is largely unknow...
氮素是植物生长发育所需的大量元素之一,水稻是我国的主要粮食作物,水稻生产对氮的需求仅次于水,是构成水稻生长成本的主要部分。目前,水稻氮肥表观利用率只有39%,即施氮肥量的50%以上残留在环境中。因此,在保证产量不减的基础上如何提高氮肥的利用效率,减少氮肥的使用量是我国农业可持续发展亟待解决的重要问题。
Background: Direct seeding is an efficient cultivation technique in rice. However, poor low temperature germinability (LTG) of modern rice cultivars limits its application. Identifying the genes assoc...
Leaf rolling and discoloration are two chilling-injury symptoms that are widely used as indicators for the evaluation of cold tolerance at the seedling stage in rice. However, the difference in cold-r...
The market success of any rice cultivar is exceedingly dependent on its grain appearance, as well as its grain yield, which define its demand by consumers as well as growers. The present study was und...
Iron plaque (IP) on root surface can enhance the tolerance of plants to environmental stresses. However, it remains unclear the impact of Fe2+ on cadmium (Cd) toxicity to rice (Oryza sativa) seedlings...
We report here the suitable explant with high efficiency of transformation and the positive effects of timentin over other antibiotics like carbenicillin and cefotaxime on the elimination of Agrobacte...
In this research, the allelopathy effect of rice hull extracts (Oryza sativa L.) on Silybum marianum and Echinochloa crus-galli was investigated. The water extracts were gotten from 13 cultivated rice...
Effects of salinity (60 mM NaCl) on 2 Turkish rice varieties (Kıral and Yavuz) were studied in comparison to 2 international check varieties (IR4630-22-2 tolerant and IR31785-58-1-2-3-3 susceptib...
Heritability is an important genetic parameter of the trait under selection. 193 F2:3 families of a cross between 'MousaTarom' and '304' were evaluated under field conditions. The studied traits were ...
Genetic diversity among twenty six genotypes of rice genotypes from four states of South Eastern Region of India was evaluated using Mahalanobis D2 statistic. The experimental materials were evaluated...
The crop management in direct-seeded rice to promote growth during the reproductive stage was evaluated in weed-controlled toposequentially intermediate fields in a small watershed in Northeast Thaila...
Rice yield is reduced by a short period of water stress at the early panicle-development stage. This study was conducted to examine the factors that reduce the panicle dry weight of rice subjected to ...
Stay-green in the post-anthesis period is thought to be an efficient drought-tolerance trait in crops, but its effectiveness in rice (Oryza sativa L.) is unknown. Our objectives were to determine whet...
