摘要: 为探究一种新型紫外多光谱补光灯对多肉植物生长的影响,以多肉植物品种火祭、红宝石、熊童子作为试验材料,设置了紫外多光谱补光(兼具UV-B波段)、普通补光(不含UV-B)和未补光(对照)3个处理,研究不同补光处理对3种多肉植物观赏特性与理化性质的影响,以期为新型紫外多光谱补光灯在冬春季多肉植物栽培上应用奠定基础。结果表明,紫外多光谱补光处理下3种多肉植物的单株质量、茎粗、花青素含量及过氧化氢酶(CAT)、过氧化物酶(POD)、抗坏血酸过氧化物酶(APX)活性指标相比于普通补光和对照都有明显提高。紫外多光谱补光处理下火祭丙二醛(MDA)含量较对照降低43.77%,熊童子叶绿素含量较对照增加18.75%。说明新型补光灯可有效提高3种多肉植物的观赏特性,增强抗氧化酶活性,提高植物抗逆性。

Abstract: In order to explore the effects of a new type of UV multispectral supplement light on the growth of succulents,the succulent varieties Crassula capitellaSedeveria pink ruby and Cotyledon tomentosa were used as test materials,on which three treatments with UV multispectral supplementary light(including UV⁃B band),ordinary supplementary light(excluding UV⁃B)and no supplementary light(control)were set.The effects of different supplementary light treatments on the ornamental feature and physicochemical properties of the three succulents were studied,to lay the foundation for application of the new type of UV multispectral supplementary light in the succulent cultivation in winter⁃spring season.Experimental results showed that the succulents’plant mass,stem thickness,anthocyanin content,catalase(CAT),peroxidase(POD),ascorbate peroxidase(APX)activities were significantly increased under UV⁃B treatment compared with the ordinary supplement light and control treatments.The content of malondialdehyde(MDA)in Crassula capitella was reduced by 43.77% compared with the control under the UV multispectral supplementary light.The chlorophyll content of Cotyledon tomentosa increased by 18.75% compared with the control under the UV multispectral supplementary light.The new type of supplementary light can effectively improve the ornamental feature of the three succulents,enhance antioxidase activity,and improve plant resistance to stress.
