Effects of Pretreatment of NaOCl, Sucrose, and Benzyladenine on Vase Life and Quality of Cut Flower in Standard Chrysanthemum ‘Jinba

유용권 인간식물환경학회 2016 인간식물환경학회지 Vol.19 No.6

This study was carried out to examine the effects of NaOCl, sucrose, and BA concentration as pretreatment solution on quality and vase life of cut flowers in Dendranthema grandiflorum ‘Jinba’. Flower diameter, fresh weight, and vase life in control and 0 mg・L -1 NaOCl treatments decreased, and the treatment with 100~200 mg・L -1 NaOCl was more effective in the quality and vase life. In pretreatment with 2.5% sucrose solution, flower diameter and fresh weight decreased and vase life was shortest due to the rapid leaf wilting. However, pretreatment with 0.1% sucrose solution increased the flower diameter and fresh weight, and showed the longest vase life. When more than 80 mg・L -1 BA was treated with pretreatment solution, flower diameter and fresh weight decreased, and vase life was shortened. With pretreatment of 20 mg・L -1 BA, the flower diameter was bigger than in the other treatments, but it was no effect on fresh weight and vase life. Therefore, it was suggested that pretreatment solution mixed with 200 mg・L -1 NaOCl, 0.1% sucrose, and 20 mg・L -1 BA was the most effective for the quality and vase life of cut flowers in standard chrysanthemum ‘Jinba’.

This study was carried out to examine the effect of postharvest storage temperature and period on vase life and quality of cut flower in standard chrysanthemum 'Jinba'. The cut chrysanthemums were treated with various temperature (1, 4, 7, 10, and 20 ℃ ) for 5, 10, and 20 days. At short-term storage for 5 days, when cut chrysanthemums were stored at 4 and 7 ℃ , quality of cut flower such as fresh weight and flower diameter was better, and vase life was more increased about 3~5 days than at the other temperatures. At storage for 10 days, the vase life of cut flower stored at 20 ℃ was decreased about 12 days, but vase life and quality of cut chrysanthemums at 1~4 ℃ treatment was better than at the others. At long-term storage for 20 days, the fresh weight, flower diameter, and water uptake highly decreased regardless of storage temperature than at storage for 5 or 10 days. The vase life was 6 days and quality were better at 1 ℃ than 4, 7, 10, and 20 ℃ . Therefore, storing at 4 ℃ was best for storage for 5 or 10 days, and storing at 1 ℃ was suitable for 20 days storage in cut chrysanthemum 'Jinba'.

This study was conducted to examine the effects of soil texture and planting depth on shoot and bulb growth in Tulipa gesneriana ‘Ile de France’, ‘Kees Nelis’, and ‘Rundy’. In physical properties of clay loam and sandy loam, Solid, liquid, and gaseous phase of sandy loam were 54.7%, 13.3%, and 32.0%, respectively. Especially, gaseous phase of sandy loam was higher by 10.6% than that of clay loam. The porosity of sandy loam was 45.3%, and it was higher by 3% than that of clay loam. The pH of sandy loam and clay loam was 6.1 and 5.8, and EC of sandy loam was lower by 0.45 level than that of clay loam in chemical properties. The cation exchange capacity of clay loam was 4.68 me/100g, and it was higher in clay loam than in sandy loam. In ‘Ile de France’ and ‘Rundy’, shoot and flowering was better in sandy loam. But, shoot growth of ‘Kees Nelis’ was good in clay loam. In clay loam, shoot growth by planting depth was not different significantly. When bulbs were planted by 4~8 cm deep in sandy loam, shoot growth was better than the others. Bulb growth was more effective in sandy loam than in caly loam. The bulb planted by 4 cm deep in clay loam and 8 cm deep in sandy loam showed the good bulb growth in circumference and diameter, and weight of main bulb. Therefore, it was desirable that bulb of tulip was planted by 8 cm deep in sandy loam for shoot and bulb growth.

유용권,김인경,Mark S. Roh,노용승,Masud Huda 한국원예학회 2017 원예과학기술지 Vol.35 No.3

The objective of this study was to determine the effect of replacing perlite (PL) with pelletsprocessed with poultry feather fiber as an inert material to prepare growing medium. The growthand flowering of Salvia splenden s ‘Vista Red’ grown in individual growing medium Biosangto®,peat moss (PM), PL, and two pellets (P45-1 and P45-2) were evaluated. Peat moss was mixedwith PL, P45-1, or P45-2 at various ratios (1:0 to 1:3 or 3:1 by volume) to investigate thefeasibility of replacing PL with pellets. Nutrient composition of the growing medium and leaftissues was analyzed. The number of florets, inflorescence length, plant height, and fresh weightof plants grown in media containing P45-1 or P45-2 were reduced compared to those grown inindividual growing medium PM or PL. As the mixing ratio of P45-1 or P45-2 to PM was higher,the growth of salvia, such as inflorescence length, plant height, number of leaves, and freshweight was inhibited. Our results indicate that mixing three parts PM with one part of P45-1(PM/P45-1/3:1) or P45-2 (PM/P45-2/3:1) accelerated flowering and increased the number offlorets and leaves compared to other mixing ratios of PM and pellets media. The concentrationsof phosphorus (P), calcium (Ca), boron (B), iron (Fe), and copper (Cu) in individual growingmedium PL, P45-1, and P45-2 were significantly lower than those in PM. The concentrationof N was the highest in leaves of plants grown in P45-1 or P45-2 amended media, and theconcentrations of P, Ca, and zinc (Zn) in leaves were lower in individual growing mediumP45-1 or P45-2 than in PM and PL. The pH of PM/P45-1/3:1 or PM/P45-2/3:1 media wasmaintained at optimal level (5.8-5.9) and the concentrations of macro- and micro-elements inthe media and leaves were considered to be optimal levels. Therefore, mixing three parts PMwith one part P45-1(PM:P45-1/3:1) or P45-2 (PM:P45-2/3:1) is recommended for improvedgrowth and flowering in salvia. This suggests that P45-1 or P45-2 can replace PL as an inertmaterial to prepare growing medium.

This study was carried out to examine the effect of scale position and cutting conditions in perforated polyethylene film bag on bulblet formation and growth in scaling of Lilium oriental hybrid 'Siberia'. Cutting with scales obtained from outer and middle position of mother bulb was more effective in bulblet formation and growth than those from inner position. The weight, diameter, height, and number of bulblets were increased at 20 and 25℃ as compared to 15 and 30℃. When 400mL water per 1L medium was treated, weight and diameter of bulblet were increased to 16% than control. Scaling media was the best in peatmoss and mixing with 1:1:1 of peatmoss:perlite:vermiculite for bulblet growth. Weight and diameter of bulblet were not decreased with mixing of 1:2(scales to medium) as compared with other treatments.

유용권,Tao Yuan,이종석,이애경,Mark S. Roh,Siro Kurita,서정근 한국원예학회 2011 Horticulture, Environment, and Biotechnology Vol.52 No.2

This study was performed to investigate the species relationships and variation of Lycoris Herb. (Amaryllidaceae) species using random amplification of polymorphic DNA (RAPD) markers. Also, single nucleotide polymorphisms (SNPs) of internal transcribed spacer 1, 5.8S ribosomal RNA gene and internal transcribed spacer 2 regions in Lycoris sanguinea var. koreana were analyzed. All accessions formed 6 major clusters; cluster A with all L. sanguinea and L. chejuensis; cluster B with 3 accessions of L. flavescens; cluster C with 8 accessions of F. flavescens var. flavescens; cluster D with 10 accessions of L. uydoensis; cluster E with L. chinensis var. sinuolata and 4 accessions of L. uydoensis; and cluster F with all L. radiata. Five haplotypes were observed; L. sanguinea and L. chejuensis having the haplotype 1 with bases of CTTATATATAT; L. chinensis var. sinuolata and all L. flavescens. Lycoris incarnata and L. aurea, non-endemic to Korea had haplotype 2 and 5, respectively. Genetic variations in L. flavescens, L. chinensis var. sinuolata, and L. uydoensis are revealed based on the analysis of molecular variances (AMOVA) and haploid types analyzed by sequence analysis. It is suggested that L. chejuensis may result from hybridization involving L. sanguinea var. koreana due to a close affinity between L. sanguinea complex and L. chejuensis. Nomenclature for L. chejuensis and L. flavescens whether they should be described as a hybrid origin should be discussed in the future.
