The study of the regulatory mechanism exogenous plant growth regulators (PGRs) on relevant physiological indicators is essential to maintain normal Rosa hybrida under high-temperature conditions. photosynthetic and characteristics ornamental cut rose ‘Carolla’ high temperature were studied by spraying leaves with various concentrations salicylic acid (SA; 0.5, 1.0, 1.5, or 2.0 mmol·L−1), 6-benzylaminopurine (6-BA; 10, 20, 30, 50 μmol·L−1), abscisic (ABA; mg·L−1), distilled water (control)....
Scape bending is the primary cause shortening vase life of cut gerbera flowers (Gerbera jamesonii ‘Harmony’). A previous study showed that this closely related to scape hardness, which attributed cell wall rigidity maintained by calcium ion bonds. In experiment, developing was sprayed with 0.5 and 1% chloride determine whether exogenous directly influences hardness it pectin crosslinks. The spray hardened 12% efficiently reduced bending, thereby prolonging flowers. 9% increase in ions (Ca2+)...
This study investigated the antimicrobial effect of chlorine dioxide (ClO2) on vase life cut rose flowers (Rosa hybrida L. 'Beast'), which were maintained in a standard holding solution containing 2% sugar. The treated with preservative solutions tap water (TW, control), distilled (DW), sucrose, and sucrose 2 μL∙L-1 to 8 ClO2. addition DW caused early leaf chlorosis, shortened compared TW or conditions, even though is well-known carbohydrate source. ClO2 significantly extended flower about...
This study was designed to investigate the effects of exogenous calcium on tolerance Rosa hybrida ‘Carolla’ high-temperature and physiological mechanisms underlying this response. Leaves grown under stress were treated by spraying four different concentrations chloride (CaCl2; 50, 100, 150, or 200 μM). The photosynthetic responses, antioxidant enzyme activities, osmotic substance contents measured at flowering stage. Temperature-stressed with CaCl2 treatment showed significantly increased...
To check the availability of indoor plants, we investigated growth and photo-physiological responses in Korean endemic Hosta minor for three months artificial low light conditions (10, 30, 50 μmol·m-2·s-1, abbreviated as L10, L30, L50). In L10 treatment, indicators leaf number size, shoot biomass, tillering capacity declined by 20–50% decline from initial values, those were maintained or slightly increased L30 treatment significantly to 200–300% L50 treatment. The use efficiency values...
We analyzed the changes in floral pigments and scent compounds of rose flowers during bud development to determine color-scent association synthesis. The two distinct petal-colored cultivars 'Penny Lane' (yellow, carotenoid type) 'Vital' (red, flavonoid were used this study. Floral buds divided into five developmental stages, S1 S5. As developed, petals or turned brilliant yellow red, with increased b* a* values, respectively. In Lane', α-carotene content did not change through but...
본 연구는 일시적인 고온 스트레스 처리가 복색 장미 'Pinky Girl'의 화아 착색과 안토시아닌 생합성 관련 유전자들의 발현 양상에 미치는 영향을 알아보고자 수행되었다. 꽃잎에서 cyanin의 축적은 화아의 발육단계와 연관이 있으며 발육 과정에서 꽃잎이 출현하는 4단계(<TEX>$S_4$</TEX>)에서 급격하게 일어났다. 따라서 <TEX>$S_4$</TEX> 단계가 꽃잎 착색에 가장 민감한 시기로 판단된다. 단계에서 3일간 스트레스(<TEX>$39/18^{\circ}C$</TEX>)를 받은 고온처리구에서 개화 당시 꽃잎의 cyanin 착색이 대조구와 비교하여 45.5% 감소하였다. 한편, 유전자인 CHS, CHI, F3'H, DFR, ANS, 3GT, 5GT의 발현은 오히려 촉진되었다. 예외적으로 F3H의 26.7% 감소하여 발현에 의미 있는 유전자로 확인되었다. 하지만 대부분 꽃잎에서의 착색 경향과 비례적이지 않았다. 화색소 번역 이후 효과와 조절유전자와 같은 생합성과...
This study investigated the antifungal effect of chlorine dioxide (ClO2) dipping on Botrytis cinerea, causal agent gray mold, cut rose flowers (Rosa hybrida L.). In vitro, spore germination mold was inhibited 100% by instant with ClO2 solution (5 to 10 μL·L−1). particular, at 5 μL·L−1 found be ideal for hindering activity without causing any damage petals. in a white cultivar 'Beast' different treatments: (one second), spraying (4.8 mL), or gassing (two hours) ClO2. Six days after treatment,...
꽃목굽음 현상(bent peduncle phenomenon, BPP)은 절화장미의 생산성 저하를 유발하는 생리적 장해의 하나로 알려져 있으나, 관련 기작이 명확히 구명되어 있지 않아 아직까지 대책 마련이 곤란한 실정이다. 이를 해결하고자 국내육성 장미 품종인 'Beast'(Rosa hybrida L. 'Beast')를 대상으로 꽃목굽음지의 화기형태, 생장, 내생 호르몬 변화 특성을 분석하였다. 화기형태 관찰을 통해 꽃목굽음지는 5개의 꽃받침조각 중 하나가 조기에 형성되고 엽상화되면서 대화현상을 나타냈다. 연중 BPP 발생 빈도는 계절에 따라 5-20%로 여름철 고온기에 급증하였다. 정상지와 비교하여 증상 외 생장량과 속도면에서 차이를 보이지 않았으나, 꽃으로의 동화산물 분배는 현저하게 감소되었다. 정상지와는 달리 꽃목굽음지에서의 IAA 함량은 화아발육기간 내내 높게 유지되었으나, <TEX>$GA_3$</TEX> 않았다. 본 연구에서 BPP는 고온과 관련된 특정 꽃받침조각의...
