Microbial growth in vase solutions and ethylene damage are often associated with premature senescence in cut flowers. We examined the efficacy of Scutellaria baicalensis Georgi extract (SC) to improve postharvest longevity and quality of two cut roses (Rosa hybrida L.) ‘Jinny’ and ‘Wild Look’ to develop an inexpensive and innocuous preservative solution for the cut flower industry. Pretreatments with 100, 200, 300, and 500 μL L−1 SC effectively extended the vase life of the cut rose cultivars. Among the tested pretreatments, 300 μL L−1 of SC was the most effective concentration and significantly prolonged the postharvest longevity of cut flowers from 11.8 days (control) to 17.4 days in ‘Jinny’ and from 13.6 (control) to 20.9 days in ‘Wild Look’. The beneficial effects of 300 μL L−1 SC pretreatment inhibited bacterial accumulation at the base of the cut stems, enhanced water uptake, and maintained initial fresh weight, positive water balance, and chlorophyll fluorescence (Fv/Fm) in the leaves of cut roses. In addition, 300 μL L−1 SC pretreatment suppressed the transcript levels of ethylene biosynthesis genes (RhACO1, RhACS1, RhACS3, and RhACS4) in rose petals and delayed flower senescence. The efficacy of 300 μL L−1 SC pretreatment in extending the vase life of cut roses was equal to 0.1 mM silver thiosulfate (STS), and greater than hydrosol (H), H + SC, and H + sucrose (H + Suc). Therefore, the results from our study highlight the potential of SC as an alternative preservative in the cut rose industry.

黄芩提取物预处理可改善切花玫瑰(Rosa hybrida L.)的采后品质

花瓶溶液中的微生物生长和乙烯损伤通常与切花的过早衰老有关。我们研究了黄芩提取物 (SC) 在提高两种切花玫瑰 (Rosa hybrida L.) 'Jinny' 和 'Wild Look' 的采后寿命和质量方面的功效,从而为切花行业开发了一种廉价且无害的防腐剂解决方案。用 100、200、300 和 500 μL L-1 SC 进行预处理有效地延长了切花玫瑰品种的瓶插寿命。在测试的预处理中,300 μL L-1 的 SC 是最有效的浓度,显着延长了切花的采后寿命,从 'Jinny' 的 11.8 天(对照)到 17.4 天,'Jinny' 从 13.6(对照)到 20.9 天。狂野的样子'。300 μL L-1 SC 预处理的有益作用抑制了切花茎基部的细菌积累,增强了吸水,并保持了切花玫瑰叶片的初始鲜重、正水平衡和叶绿素荧光 (Fv/Fm) . 此外,300 μL L-1 SC 预处理抑制了玫瑰花瓣中乙烯生物合成基因(RhACO1、RhACS1、RhACS3 和 RhACS4)的转录水平并延迟了花朵衰老。300 μL L-1 SC预处理延长切花瓶瓶寿命的效果相当于0.1 mM硫代硫酸银(STS),且大于纯露(H)、H + SC和H +蔗糖(H + Suc) . 因此,我们的研究结果突出了 SC 作为切花玫瑰行业替代防腐剂的潜力。正水平衡和切花玫瑰叶子中的叶绿素荧光 (Fv/Fm)。此外,300 μL L-1 SC 预处理抑制了玫瑰花瓣中乙烯生物合成基因(RhACO1、RhACS1、RhACS3 和 RhACS4)的转录水平并延迟了花朵衰老。300 μL L-1 SC预处理延长切花瓶瓶寿命的效果相当于0.1 mM硫代硫酸银(STS),且大于纯露(H)、H + SC和H +蔗糖(H + Suc) . 因此,我们的研究结果突出了 SC 作为切花玫瑰行业替代防腐剂的潜力。正水平衡和切花玫瑰叶子中的叶绿素荧光 (Fv/Fm)。此外,300 μL L-1 SC 预处理抑制了玫瑰花瓣中乙烯生物合成基因(RhACO1、RhACS1、RhACS3 和 RhACS4)的转录水平并延迟了花朵衰老。300 μL L-1 SC预处理延长切花瓶瓶寿命的效果相当于0.1 mM硫代硫酸银(STS),且大于纯露(H)、H + SC和H +蔗糖(H + Suc) . 因此,我们的研究结果突出了 SC 作为切花玫瑰行业替代防腐剂的潜力。300 μL L-1 SC预处理延长切花瓶瓶寿命的效果相当于0.1 mM硫代硫酸银(STS),且大于纯露(H)、H + SC和H +蔗糖(H + Suc) . 因此,我们的研究结果突出了 SC 作为切花玫瑰行业替代防腐剂的潜力。300 μL L−1 SC 预处理对延长切花玫瑰瓶插寿命的功效相当于 0.1 mM 硫代硫酸银 (STS),且大于纯露 (H)、H + SC 和 H + 蔗糖 (H + Suc) . 因此,我们的研究结果突出了 SC 作为切花玫瑰行业替代防腐剂的潜力。
