“…Previous studies reported that exogenous BAP treatment enhanced inflorescence emergence and this promotive effect increased with increasing BAP concentrations in Phalaenopsis [25,27]. In this study, BAP also increased inflorescence numbers (Figure 4).…”

“…CKs remained in active forms under forcing condition, while the CKs in leaves were converted from active to inactive glucoside forms at vegetative high temperature in Phalaenopsis [24]. Exogenous 6-benzylaminopurine (BAP) spray during a low-temperature exposure accelerated inflorescence emergence and increased inflorescence numbers [25,26], and inflorescence length decreased with increasing BAP concentrations [27]. Also, CKs can be used in callus formation and shoot regeneration for vegetative propagation from inflorescences in Phalaenopsis [28][29][30].…”

This study was conducted to observe the effects of exogenous gibberellic acid3 (GA3) and 6-benzylaminopurine (BAP) treatments on the growth and inflorescence initiation of Phalaenopsis and to determine whether hormonal applications can substitute for low-temperature exposure for floral transition. Phalaenopsis Queen Beer ‘Mantefon’ clones were treated with no hormones (control), GA3 100 mg/L, GA3 200 mg/L, BAP 100 mg/L, and GA3 100 mg/L + BAP 100 mg/L by foliar spray. The treatments were carried at 28 °C for vegetative growth and 20 °C for forcing, respectively. At 28 °C of vegetative temperature, all exogenous hormonal treatments did not induce inflorescence initiation, but lateral shoots were observed in BAP-treated plants even though this plant is a monopodial orchid. GA3 significantly increased leaf length and decreased leaf width, and consequently increased length:width (L:W) ratio compared with the control and BAP alone. The trend grew as GA3 concentration increased. Also, the GA3 increased stem length and decreased stem diameter. At 20 °C of forcing temperature, L:W ratio responded similarly to 28 °C in GA3 treatments, but leaf size was smaller than for the control or BAP alone. BAP accelerated inflorescence emergence and significantly increased inflorescence numbers, whereas GA3 and GA3 + BAP slightly delayed inflorescence emergence. GA3 significantly promoted new leaf development at 20 °C of forcing condition. These results indicated that cytokinin was associated with the break of axillary vegetative and inflorescence meristems and exogenous GA3 spray did not improve inflorescence initiation in Phalaenopsis. Although exogenous hormonal application did not substitute for low-temperature exposure, it showed a possibility in promoting the growth and inflorescence initiation.

“…Orchid plants are widely used as a pot flower among many flowering plants (Park et al, 2011), and phalaenopsis is popular around the world (An et al, 2017). As its flowers are colorful, beautiful and showy, it has been widely cultivated (Park et al, 2011).…”

This study aimed to provide basic data on current trends in floriculture through a survey. The exhibitors' purposes and items displayed at the Tokyo International Flowers & Plants Expo in 2017 were surveyed. The survey was conducted among 238 exhibitors during the exhibition period from October 11 to 13, 2017. As a result, participants came from 14 countries including Belgium, China, Colombia, Japan, Korea and France. The purposes of the majority of the surveyed exhibitors were to display cultivars (86 exhibitors, 36.3%), followed by to display merchandise, subsidiary materials and cultivation techniques. Among cultivars, pot plants accounted for the majority of the entire cultivars (54 exhibitors, 55.1%), followed by cut flowers (35 exhibitors, 35.7%), sapling, and seeds. The most of the displayed pot plants were ornamental plants (27 exhibitors, 43.5%), followed by garden trees, ground cover plants, bedding plants and succulent plants. The most of the displayed cut flowers were rose (8 exhibitors, 21.1%), followed by lisianthus, chrysanthemum and dahila. In terms of cultivation techniques, those using moss were displayed by 7 exhibitors (50%) and green-wall techniques were displayed by 6 exhibitors (42.9%). In terms of merchandise, processed products were displayed by 21 exhibitors (41.2%), followed by floral products. Therefore, the IFEX can be used as a place to understand current trends in the floriculture market.
