Abstract:
In order to establish suitable light quality for the growth of red raspberry tissue culture plantlets，using red raspberry ‘Heritage’ tissue culture plantlets as experimental material，the morphology，anntioxidant enzyme activity，carbon and nitrogen metabolism were studied.The results showed that，with the increasing of R/B(ratio of red to blue)，red raspberry tissue culture plantlet′s height gradually increased from 1514 cm to a maximum of 1638 cm，it was the maximum value at 4R/B(red∶blue=4∶1)，but the difference was not significant with W(white)，then the height of the plant decreased with the increase of R/B，the minimum value was 0681 cm at 10R/B(red∶blue=10∶1)，significantly less than the W.Stem diameter from a maximum of 0101 cm reduced to the minimum value of 0076 cm with the increase of R/B，it was the maximum value at R/4B(red∶blue=1∶4)，the difference was significant with W，it was the minimum value at 10R/B.Leaf area，rooting rate and root length showed the same trend with stem diameter，all decreased with the increase of R/B，it was the maximum value at R/4B，was 0751 cm2，0786，1369 cm，it was the minimum value at 10R/B,was 0211 cm2，0357,0369 cm；SOD and CAT activity increased gradually from the minimum value(1832 μg?g-1FW，H2O25902 mg?g-1FW) of R/4B to the maximum value(10953 μg?g-1FW，H2O2 46978 mg?g-1FW) of 10R/B with the increase of R/B;POD activity increased gradually from the minimum value(5511 μg?g-1FW) of R/4B to the maximum value(20934 μg?g-1FW) of 4R/B，and then gradually decreased with the increase of R/B；MDA content increased gradually from the minimum value(7357 nmol?g-1FW) of R/4B to the maximum value(10880 nmol?g-1FW) of 10R/B with the increase of R/B.Carbohydrate content increased gradually from 200204 mg?g-1 to the maximum value(313917 mg?g-1)，it was the maximum value at R/B and very significantly higher than W，then gradually decreased with the increasing of R/B，the minimum value was 154172 mg?g-1 at 10R/B，significantly lower than W.The content of free amino acid increased gradually from the minimum value(16903 mg?g-1) of R/4B to the maximum value(33180 mg?g-1) of 10R/B with the increase of R/B.Soluble protein content gradually decreased from the maximum value(12507 mg?g-1) of R/4B to the minimum value(2147 mg?g-1) of 10R/B with the increase of R/B．
