采后莲（Nelumbo nuciferacvs. Sattabongkot和Saddhabutra）的花显示出快速的花瓣变黑，这缩短了花的瓶插寿命。研究了EthylBloc香囊和/或2，4-吡啶二羧酸（PDCA）对两个商品品种花瓣黑变和瓶插寿命的影响。用蒸馏水（对照）、EthylBloc 2小袋（活性成分0.014%，以256 ppb熏蒸6小时）、2，4-PDCA的瓶插溶液（2.0mM）或EthylBloc小袋和2，4-PDCA的组合处理切花。2，4-PDCA和EthylBloc香囊的组合导致最长的瓶插寿命'Sattabongkot'和'Saddhabutra'分别为49.8 h和69.0 h，而对照值分别为44.4和36.0 h。EthylBloc小袋和2，4-PDCA的组合增加了水吸收，延迟了重量降低和色调角变化，并减少了花瓣变黑。此外，处理导致更少的乙烯产生和更少的呼吸在花比其他处理。该方法可用于商业切花的处理。
Postharvest lotus (Nelumbo nuciferacvs. Sattabongkot and Saddhabutra) flowers show a rapid petal blackening which shortens the vase life of flowers. We studied the effect of EthylBloc Sachet and/or 2,4-pyridinedicarboxylic acid (PDCA) on the petal blackening and the vase life of two commercial cultivars. Cut flowers were treated with distilled water (control), EthylBloc 2 Sachet (active ingredient 0.014%, fumigation for 6 h at 256 ppb), vase solution of 2,4-PDCA (2.0 mM) or the combination of EthylBloc Sachet and 2,4-PDCA.All treatments were kept at 28 ± 1 °C and 80–85% RH. The combination of 2,4-PDCA and EthylBloc Sachet caused the longest vase lives of 49.8 h with ‘Sattabongkot’ and 69.0 h with ‘Saddhabutra’, when the control values were 44.4 and 36.0 h, respectively. The combination of EthylBloc Sachet and 2,4-PDCA increased water uptake, delayed weight decrease and hue angle change, and reduced petal blackening. Moreover, the treatment caused less ethylene production and less respiration in the flowers than the other treatments. This method is useful for handling in commercial cut lotus flower.
