为了研究不同光质光强处理对金线莲组培苗生长的影响,采用不同光质LED作为人工光源对漳州金线莲进行继代培养。结果显示:红光处理有利于株高生长,其叶绿素含量、Fv/Fm和Fv/Fo值均较小,其中70μmol/(m2· s)红光处理时金线莲高度达到6.26 cm,但此时其叶绿素a含量、叶绿素b含量、叶绿素总量、Fv/Fm和Fv/Fo值仅分别为1.19 mg/g、0.55 mg/g、1.73 mg/g、0.572和1.34;绿光对金线莲各项指标均无促进作用,且不同强度处理之间差异不显著;蓝光处理对金线莲组培苗叶片生长和生物量积累均有促进作用,金线莲叶绿素含量、Fv/Fm和Fv/Fo值相对较高,但会抑制株高生长,其中70μmol/(m2· s)蓝光处理时金线莲鲜重、干重、干重/鲜重、叶绿素a含量、叶绿素b含量、叶绿素总量、Fv/Fm和Fv/Fo值分别为1.47 g、0.19 g、0.130、1.83 mg/g、0.71 mg/g、2.54 mg/g、0.801和4.02,但其高度仅为4.56 cm。由此得出,红光有利于植物地上部分生长,但是会造成植株徒长,绿光对植物光合作用影响较小,蓝光对组培苗具有一定的矮化壮苗作用。
為瞭研究不同光質光彊處理對金線蓮組培苗生長的影響,採用不同光質LED作為人工光源對漳州金線蓮進行繼代培養。結果顯示:紅光處理有利于株高生長,其葉綠素含量、Fv/Fm和Fv/Fo值均較小,其中70μmol/(m2· s)紅光處理時金線蓮高度達到6.26 cm,但此時其葉綠素a含量、葉綠素b含量、葉綠素總量、Fv/Fm和Fv/Fo值僅分彆為1.19 mg/g、0.55 mg/g、1.73 mg/g、0.572和1.34;綠光對金線蓮各項指標均無促進作用,且不同彊度處理之間差異不顯著;藍光處理對金線蓮組培苗葉片生長和生物量積纍均有促進作用,金線蓮葉綠素含量、Fv/Fm和Fv/Fo值相對較高,但會抑製株高生長,其中70μmol/(m2· s)藍光處理時金線蓮鮮重、榦重、榦重/鮮重、葉綠素a含量、葉綠素b含量、葉綠素總量、Fv/Fm和Fv/Fo值分彆為1.47 g、0.19 g、0.130、1.83 mg/g、0.71 mg/g、2.54 mg/g、0.801和4.02,但其高度僅為4.56 cm。由此得齣,紅光有利于植物地上部分生長,但是會造成植株徒長,綠光對植物光閤作用影響較小,藍光對組培苗具有一定的矮化壯苗作用。

To research the effect of different light quality and the light intensity treatment on the growth of Anoectochilus roxburghii tissue culture seedling, the LED light source was used as an artificial light source for A.roxburghii in Zhangzhou to subculture. The results showed that red light treatment was benefit to the growth of A.roxburghii height, chlorophyll content, Fv/Fm and Fv/Fo values were smaller. Among them, the shoot high of A.roxburghii was up to 6.26 cm under 70μmol/(m2 · s) red light, but the chlorophyll a, chlorophyll b, total content of chlorophyll, Fv/Fm and Fv/Fo were only 1.19 mg/g, 0.55 mg/g, 1.73 mg/g, 0.572 and 1.34;the effect of green light was not obvious for the indicators of A.roxburghii, and no significant difference between different intensities;there was a promoting effect on accumulation of biomass and chlorophyll and Fv/Fm and Fv/Fo of A.roxburghii under the blue light treatment, but certain inhibitory effect on plant height, among them. Under the blue light treatment of 70 μmol/(m2 · s), the chlorophyll a, chlorophyll b, total content of chlorophyll, fresh weight, dry weight, the ratio of dry weight to fresh weight, Fv/Fm and Fv/Fo were up to 1.47 g, 0.19 g, 0.130, 1.83 mg/g, 0.71 mg/g, 2.54 mg/g, 0.801 and 4.02, respectively, but the shoot high of A.roxburghii was only 4.56 cm. Therefore, the red light was advantageous to the growth of aerial parts of plants, the green light had little impact on plant photosynthesis, and there were certain effect on dwarfed and strong tissue culture seedling under the blue light.
