摘要

研究了1-甲基环丙烯(1-MCP)和硒(Se)对水仙采后品质和花瓶寿命的影响。采用1- mcp浓度为0、0.5和1 μL -1, Se浓度为0、1和2 mg L-1，采用完全随机设计的因子试验，设3个重复(每个重复4朵切花)。结果表明，1-MCP和Se处理显著提高了柽柽花插花的瓶龄、吸水性和相对鲜重。在1 μL L-1 - mcp处理下，花鲜重由对照0.58 g提高到0.92 g。1-MCP和硒处理后，花的总可溶性固形物(TSS)和总可溶性糖(TSS)均显著低于对照。1-MCP和硒处理的切花总酚含量和抗氧化活性均显著高于对照。1 μL L-1 1- mcp处理的瓶龄最高，为13.41 d。研究表明，施用1-MCP和硒可延缓花期衰老症状，延长花瓶寿命和采后品质。

Extending vase life of Narcissus tazetta L. cut flowers using selenium and 1-methylcyclopropene treatments

The effects of 1-methylcyclopropene (1-MCP) and selenium (Se) on postharvest quality and the vase life of Narcissus tazetta were investigated. A factorial experiment based on a completely randomized design with 1-MCP at concentrations of 0, 0.5, and 1 μL L-1 and Se at 0, 1 and 2 mg L-1 with 3 replicates (4 cut flowers per each replicate) was conducted. The results showed that treatment of cut flowers with 1-MCP and Se significantly increased the vase life, water uptake and relative fresh weight of N. tazetta cut flowers. Fresh weight of flower increased from 0.58 (control) to 0.92 g using 1 μL L-1 1-MCP treatment. Total soluble solids (TSS) and total soluble sugar of flowers treated with all the levels of 1-MCP and Se significantly decreased as compared to control. Total phenolic content and antioxidant activity of treated cut flowers with 1-MCP and Se were significantly increased in comparison to the control. The highest (13.41 days) vase life was obtained in 1 μL L-1 1-MCP treatment. The study revealed that application of 1-MCP and Se delayed senescence symptoms resulting extended vase life and postharvest quality of N. tazetta cut flowers.
