外源硒对砀山酥梨果实品质和硒含量的影响
Effect of Spraying Exogenous Selenium on Fruit Quality and Selenium Content of Dangshan Suli
摘要
Abstract
In this study,Pyrus bretschneider Rehd.‘Dangshan Suli’ trees were used as materials,and dif-ferent concentrations of sodium selenite(0,5,10,20 mg/L) were sprayed to the trees to analyze the effect of selenium( Se) on the fruit quality and the Se content in fruit. The results showed that spraying exoge-nous Se could improve the single fruit weight,vertical length,transverse length,flesh firmness(FF),and the content of Se,sucrose and soluble solid( SS) in fruit. However,spraying Se had no significant effect on the total sugar and acid content,as well as the ratio of sugar to acid. When the spraying dosage of Se was 5 mg/L ,the FF and the content of SS and Se in fruit significantly increased by 10. 09%,6. 08% and 35. 71% respectively(P<0. 05),the sucrose content in fruit significantly increased by 36. 21%(P<0. 01). When the spraying dosage of Se was 10 mg/L,the fruit weight and the fruit transverse length sig-nificantly increased by 11 . 16% and 2 . 81% respectively ( P <0 . 05 ) . When the spraying dosage of Se was 20 mg/L, the fruit weight and the fruit transverse length significantly increased by 17. 93% and 4. 22% respectively(P<0. 01),but the Vc content significantly increased by 12. 81%(P<0. 05). The Se dosage was significantly positively correlated with the Se content in fruit,the single fruit weight and the fruit transverse length,and significantly negatively correlated with the fruit shape index and the Vc content in fruit(P<0. 05). Therefore,the 5 mg/L Se should be sprayed to the pears for improving the fruit quali-ty,and the Se content at the young or rapid growing stage of the fruit.关键词
