| 摘 要： | 以粳稻品种沈农6014及沈农265为试验材料,采用盆栽方法,研究紫外线-B增强对水稻的产量及品质的影响.试验设3个处理,即自然光照(TCK)处理、紫外辐射增强5%(T1)和增强10%(T2)处理.结果表明:紫外线-B增强能够降低水稻产量及产量构成因素,降低水稻籽粒糙米率(0.66%～7.06%)、整精米率(5.65%～18.88%)、平白粒率(22.17%～40.16%)、籽粒面积(2.61%～6.25%)、脂肪酸含量(1.23%～54.19%)和食味值(1.07%～16.78%),使籽粒中蛋白质含量(4.65%～10.71%)和直链淀粉含量(0.56%～4.81%)增高,且紫外线-B增强在T2处理下对水稻产量及品质的影响高于T1处理. |

| Abstract: | The effects of enhanced UV-B radiation on yield and quality of two rice cuhivars (ShenNong 6014 and ShenNong 265) are studied in potted method. There were three treatments including natural light (TCK), enhanced 5% UV-B radiation (T1) and enhanced 10% (T2). The results showed that enhanced UV-B radiation decreases yield components, the percentage of brown rice(0.66%-7.06%), head rice rate(5.65%-18.88%), the rate of white rice(22.17%-40.16%), grain area(2.61%-6.25%),fatty acid contents (1.23%-54.19%)and eating quality ( 1.07%- 16.78% )but increasea protein content (4.65%-10.71% ) and amylose content of rice(0.56%-4.81%). The effects of T2 was stronger than TI. |
