“…A previous study has shown that in Phalaenopsis, CO 2 fertilization increased the fresh weight, the number of inflorescences, and the flower size, but the treatment effects differed based on the fertilization season (Endo and Ikushima, 1997). The flower size of Phalaenopsis was similar to that of its control under CO 2 fertilization of 800 mol•mol -1 , which suggests that the EC and N:K ratios were more influencing factors than CO 2 fertilization (Cho et al, 2020). In contrast, when the high concentration of CO 2 is fertilized, the leaves' stoma closes, reducing the transpiration and increasing the plant's temperature (KSFS, 2021).…”

“…The b and h values of the petals increased after CO 2 fertilization treatments, regardless of the HOCl treatment. Cho et al (2020) showed that the petal color of Phalaenopsis was not affected by CO 2 fertilization and the EC level (Cho et al, 2020).

“…In a closed greenhouse, when plants absorb CO 2 through photosynthesis after sunrise, the CO 2 levels reduce to 150 mol•mol -1 in the greenhouse (Pan et al, 2019;KSFS, 2021;Jung et al, 2022;. CO 2 fertilization of 1,000-1,500 mol•mol -1 after sunrise increased the number of roses by 10-20%, and CO 2 800 mol•mol -1 positively affects the flower spike length, the number of lateral branches, and flower buds, and day to the flowering of Phalaenopsis (Cho et al, 2020;RDA, 2020). The CO 2 fertilization of 1000 mol•mol -1 prolonged vase life by 30 days and increased the sugar contents of the flower stalk on Phalaenopsis (Endo and Ikushima, 1997).…”

This study investigates the effect of CO 2 fertilization before harvest using 800 mol•mol -1 from November 2021 to May 2022 and vase solution treatment using slightly acidic electrolyzed water (HOCl 5 µL•L -1 , pH 5.0 -6.5) after harvest of Hydrangea macrophylla 'Moonstar'. The CO 2 fertilization + HOCl treatment was the longest extension of the vase life and the largest total vase solution uptake. The vase solution treatment of HOCl influenced the vase life to a greater extent than by CO 2 fertilization. In the CO 2 fertilization treatment, the HOCl treatment reduced the number of bacteria on the end of stems by 54% compared to that achieved without HOCl treatment. It was higher on the relatively fresh weight and vase solution uptake in CO 2 fertilization + HOCl treatment than that of control after 6 days of treatment. The CO 2 fertilization + TW or HOCl treatments maintained the initial fresh weight for up to 6 days after treatment. There was no difference in the ΔE value, and chlorophyll contents of leaves and flower size did not differ in all treatments. Therefore, the initial sterilization on the end of stems after harvest was an essential factor for improving the quality of cut hydrangea flowers. The vase solution treatment of HOCl 5 µL•L -1 after harvest extended the vase life of cut hydrangea flowers.

“…Ketika seluruh persyaratan fisiologis dan lingkungan terpenuhi, tanaman anggrek dapat memunculkan tunas reproduksi, yang selanjutnya berkembang menjadi bunga (Guo et al, 2012), sehingga pengendalian lingkungan pembungaan memiliki potensi yang cukup besar dalam mempengaruhi kualitas bunga yang dihasilkan. Karakteristik fisiologi anggrek, khususnya hubungan laju fotosintesis dalam kaitannya dengan iklim dan fenologi tumbuhan, sangat penting untuk peningkatan kualitas pembungaan anggrek (Cho et al, 2020). Selain itu, kuantitas dan waktu penyinaran seringkali bervariasi karena posisi dalam peletakan tanaman terhadap cahaya matahari.…”

Orchid is an ornamental plant with high economic value and prospective to be cultivated. Flower development is influenced by genetic, physiological or environmental factors, such as light intensity, so controlling the flowering environment has considerable potential in influencing the quality of the flowers produced. The purpose of this study was to determine the effect of light intensity from the west and from the east on the flowering and photosynthesis of Dendrobium orchids. This study used a completely randomized block design (RAKL). In this treatment there were 2 treatment factors which were repeated three times. The factor is sunlight with 2 times, namely T1: Morning – Afternoon and T2: Afternoon – Evening. The second factor is Orchid variety (V) V1 : BJS (Burane Jade Snow), V2 : TGUY (Tongchai Gold Uday Yellow), V3 : BJW (Burane Jade White), V4 : CG (Caesar Gold), V5 : PS ( Pure Smiles). The results showed that the number of blooms and the rate of photosynthesis increased in V1, V2, V4, and V5 planted at T1, but decreased in V3 when planted at T1, in V4 there was no difference in photosynthesis at T1 and T2, but the number of flowers blooming decreased at T2.
