- 摘要:
- 以普通日光灯白光(W)为对照，研究了LED红光（R）、蓝光（B）、红光+蓝光（1RB）、2红光+蓝光（2RB）、4红+2蓝+1绿（RBG）、6红+1蓝+1白（RBW）和UVB（紫外B）光源对“美人酥”红梨果实转色过程中果实品质的影响。结果表明：不同光质照射离体脱袋果实25 d，花青苷合成效应依次为UVB＞B＞2RB＞W＞1RB＞RBW＞RBG＞R；不同光质对果皮PAL的含量均与花青苷含量不呈正相关；1RB促进果实可溶性蛋白含量的效果最佳；UVB对果实中可滴定酸含量的影响最大；RBW和UVB能显著增强“美人酥”果实的可溶性糖含量。因此，可通过照射UVB或红蓝组合的光源来提高红梨“美人酥”果实转色期的果实品质。
- Abstract:
- Taking common fluorescent white light as control，the effects of fruit color-changed and quality of ‘Meirensu’ red Chinese sand pear under treatments of red LEDs(R)，blue LEDs (B)，the LEDs combination of red and blue light(1RB)，(2RB),the LEDs combination of red，blue and green light(RBG)，the LEDs combination of red，blue and white light（RBW）,the UVB were investigated．The results showed that fruits of ‘Meirensu’detatched from trees under irradiation of different treatment after 25 days，the effect of anthocyanin biosynthesis was UVB＞B＞2RB＞W＞1RB＞RBW＞RBG＞R；there was no directly positively relativity between the anthocyanin and activity of PAL enzyme；under 1RB，the content of soluble protein was the highest；the effect of UVB was the most powerful in organic acid biosynthesis；RBW and UVB could markedly enhance soluble sugar content.Therefore,there were a lot of ways to improve the fruit quality by UVB,1RB and RBW radiation in color changed period.
