摘要

We examined the effects of 6-benzylaminopurine (BA), a synthetic cytokinin, on post-shipping quality and metabolic changes in Phalaenopsis orchids following simulated dark shipping (SDS). Eighteen-month-old Phalaenopsis Sogo Yukidian ‘V3’ plants were treated with various concentrations of BA (0 [control], 20, 40, 80, and 160 mg·L−1) via foliar application. The plants were subjected to a 30-day SDS to simulate the stress experienced during extended dark shipping. BA application significantly reduced leaf yellowing and abscission following SDS, with the most effective results observed at 80 and 160 mg·L−1. These higher concentrations notably accelerated inflorescence emergence and blooming, shortening the flowering period by up to 65 days compared with the control. Additionally, BA application increased sucrose and glucose levels in both shoots and roots after SDS treatment, particularly at the highest BA concentration. Hormonal analysis revealed reduced abscisic acid levels in the roots across all BA treatments. These findings suggest that pre-shipment application of BA can effectively enhance post-shipping quality in Phalaenopsis orchids by delaying leaf senescence and improving carbohydrate and hormone balance during dark transport. Thus, BA treatment could serve as a strategic approach to maintain the commercial and aesthetic value of Phalaenopsis orchids following shipment.
