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.
