Abstract: Using Rosa hybrida‘Red Meilland’of landscape plants as the test material,this study investigated the effects of green to red light conversion agents(LCA1),purple to red light conversion agents(LCA2),and green purple to red blue compound light conversion agents(LCA3)on the agronomic traits,chlorophyll content,chlorophyll fluorescence parameters,photosynthetic parameters,and stomatal characteristics of cut roses.The results showed that the addition of light conversion agent film under cover helped to improve the height,stem diameter,and petal diameter of roses,but had no significant effect on the number of rose branches. Only LCA3 treatment had a significant impact on the flowering period of roses. Compared with the common PO film control(CK)treatment without light conversion agent,the LCA3 treatment increased the content of chlorophyll a,chlorophyll b,and chlorophyll a+b in roses by 29.5%,54.5%,and 33.6%,respectively,while the content of chlorophyll a/b decreased by 14.9%,with no significant effect on carotenoid content;the maximum photochemical quantum efficiency(Fv/Fm),potential activity(Fv/Fo),actual photochemical quantum efficiency(ΦPSⅡ),effective photochemical quantum efficiency(Fv´/Fm´),photochemical quenching coefficient(qP),and relative electron transfer rate(ETR)of rose leaves increased by 6.9%,55.3%,1.6%,53.6%,11.8%,and 35.2%,respectively.The thickness,stomatal density,length,and width of rose leaves increased by 15.1%,35.8%,15.8%,and 38.3%,respectively. Covering with different light transfer films helped to increase the net photosynthetic rate(Pn),transpiration rate(Tr),stomatal conductance(Gs),water use efficiency(WUE),and stomatal limitation value(Ls)of roses,while reduced intercellular carbon dioxide concentration(Ci).At the same time,LCA3 treatment had a higher effect on reducing the release of ethylene from roses and increasing the activities of superoxide dismutase(SOD),peroxidase(POD),and catalase(CAT)compared to LCA2,LCA1,and CK treatments. In summary,LCA3 treatment has the best effect on improving rose photosynthesis,increasing chlorophyll content and chlorophyll fluorescence parameters,and improving the agronomic traits of roses.

摘要: 以园林植物玫昂红切花月季为试材,探究绿光转红光转光剂(LCA1)、紫光转红光转光剂(LCA2)及绿紫光转红蓝光复配型转光剂(LCA3)对切花月季农艺性状、叶绿素含量、叶绿素荧光参数、光合参数以及气孔特征的影响。结果表明,添加不同转光剂膜覆盖有助于提高月季株高、茎粗、花瓣花径,但对月季分枝数无显著影响,仅LCA3处理下对月季花期有显著影响,较不添加转光剂的普通PO膜对照(CK)增加0.7 d。与CK 相比,LCA3处理下月季叶绿素a、叶绿素b、叶绿素a+b 含量分别增加29.5%、54.5%和33.6%,叶绿素a/b下降14.9%,对类胡萝卜素含量变化无显著影响;月季叶片PSⅡ最大光化学量子效率(Fv/Fm)、PSⅡ潜在活性(Fv/Fo)、PSⅡ实际光化学量子效率(ΦPSⅡ)、PSⅡ有效光化学量子效率(Fv´/Fm´)、光化学猝灭系数(qP)和电子相对传递速率(ETR)较CK 分别增加6.9%、55.3%、1.6%、53.6%、11.8%和35.2%;月季叶片厚度、气孔密度、气孔长度、气孔宽度分别增加15.1%、35.8%、15.8%和38.3%。不同转光膜覆盖有助于提高月季净光合速率(Pn)、蒸腾速率(Tr)、气孔导度(Gs)、水分利用效率(WUE)以及气孔限制值(Ls),而降低胞间二氧化碳浓度(Ci)。同时,LCA3处理降低月季乙烯释放量以及增加超氧化物歧化酶(SOD)、过氧化物酶(POD)以及过氧化氢酶(CAT)活性的效果高于LCA2、LCA1及CK。综上可知,LCA3处理提高月季光合作用,增加叶绿素含量及叶绿素荧光参数,改善月季农艺性状的效果最好。
