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%)、垩白粒率(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。
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 T1.
