Plant growth-promoting rhizobacteria are known to enhance the growth and antioxidant activity of several plants. However, effects such on Geum aleppicum, a plant with pharmacological potential in Korea unknown. In this study, we investigated Pseudarthrobacter sp. NIBRBAC000502770 treatment (100 mL/pot, every two weeks for 55 days), form culture medium, 100-fold diluted culture, supernatant, pelleted cells resuspended water, growth, antibacterial flavonoid content G. aleppicum. The strain...

The objective of this study was to investigate the effect light quality on growth and contents photosynthetic pigments total flavonoids, parameters chlorophyll a fluorescence, antioxidant capacities, enzyme activities. It intended preliminarily explore internal mechanisms involved for physiology Carpesium triste Maxim. Stem apex explants were cultured Murashige Skoog (MS) medium under white (W), red (R), blue (B), or 1:1 mixture (RB) light-emitting diodes (LEDs) four weeks. RB induced sturdy...

The current study has determined the effect of red and blue lights on enhancement growth, antioxidant property, phytochemical contents, expression proteins in Scrophularia kakudensis . In vitro -grown shoot tip explants S. were cultured plant growth regulator-free Murashige Skoog (MS) medium under conventional cool white fluorescent lamp (control), light-emitting diodes (LED) light, or LED light. After 4 weeks, stomatal ultrastructure, total phenols flavonoids, activities enzymes, protein...

This research examined the effects of supplementary or night-interrupting (NI) blue (B) light supplied at a low intensity on flowering, gene expression, and morphogenesis chrysanthemum, qualitative short-day plant. White (W) light-emitting diodes (LEDs) were used to provide with photosynthetic photon flux density (PPFD) 180 μmol·m−2·s−1 during photoperiod grow plants in plant factory. The control group was constructed that exposed 10-h short day (SD10) treatment without any light. B this for...

본 실험은 밀폐형 식물생산시스템에서 인공광원과 광조사 시간에 따른 잎상추 '선홍적축면' 품종의 적정 생육 조건을 구명하고자 수행하였다. 상추 유묘를 3종류의 인공광원인 형광등과 에프씨 포이베(사)와 헤파스(사)의 백색 LED 아래에서 재배하였고, 시간을 각각 12/12, 18/6, 24/0(명기/암기)으로 처리하였다. 광파장대를 측정한 결과 형광등은 400-700nm 범위에서 다양한 피크를 나타냈지만, 2종류의 LED에서는 450nm와 550nm의 파장대역에서만 나타냈다. 초장, 생체중 및 건물중은 처리하였을 때 가장 우수했다. 또한 엽면적도 시간 24/0(명기/암기) 처리구에서 좋았다. 형광등 처리가 LED와 비교하여 최대근장, 엽수, 총 안토시아닌 함량이 우수하였다. 엽록소 형광값은 형광등을 사용하여 12/12(명기/암기)로 높았다. 광원에서 광 에너지 사용 효율은 등이 약 35-46% 더 결과는 식물공장 시스템에서 재배를 위한 형광등의 대체 광원으로써 LED의...

The purpose of this study was to determine the effect light quality on R.hongnoensis growth, physiology, and antioxidant properties. Five conditions were employed, including white (control), red (R), blue (B), combined LED R, green (G), B at 7:1:2 (RGB), as well G, B, far-red (Fr) 7:1:2:1 (RGBFr). R had greatest growth-promoting based plant height, leaf length, width, stem diameter, area. However, width root length exhibited growth under RGB. fresh dry weight shoots roots highest RGB light....

The current study deals with in vitro propagation, antioxidant property estimation, and assessment of acacetin content Scrophularia kakudensis Franch. Adventitious shoot induction was achieved from the nodal explant highest number adventitious shoots per (17.4) on Murashige Skoog’s (MS) medium fortified 2.0 mg·L −1 6-benzyladenine (BA) 0.5 mg L indole-3-acetic acid (IAA). Maximum roots plant (16.5) noted half strength MS supplemented IAA. regenerated plants displayed successful survival...

Although grafting is broadly used in the production of crops, no information available about proteins involved vascular connections between rootstock and scion. Similarly, proteome changes under light intensities widely for grafted seedlings are practical use. The objective this study was to determine using watermelon (Citrullus vulgaris Schrad.) 'Sambok Honey' 'Speed' as scion bottle gourd (Lagenaria siceraria Stanld.) 'RS Dongjanggun' grown different (25, 50, 75 100 μmol m−2 s−1). Our...

Aldose reductase (ALR2), a vital enzyme involved in polyol pathway, has befitted as novel drug target antidiabetes discovery process. In the present study, binding mode and pharmacokinetic properties of potential polyphenolic compounds with reported aldose inhibitory activity from genus Scrophularia have been investigated. The human ALR2 (PDB ID: 2FZD) acted receptor current study. Among investigated, acacetin, methoxy flavonoid, displayed stable to active site least energy value. Molecular...

Chrysanthemum (Dendranthema grandiflorum Kitamura), a qualitative short-day plant, does not produce flowers when the night length is shorter than cultivar-dependent critical value. Flowering effectively inhibited required uninterrupted period broken by short periods of exposure to interruption lights (NILs). The effects quality and positioning NIL on morphogenesis, flowering, photoperiodic gene expressions chrysanthemum were investigated. Blue (NI-B), red (NI-R), far-red (NI-Fr), white...

The rose is one the most commercially grown and costly ornamental plants because of its aesthetic beauty aroma. A large number pests attack buds, flowers, leaves, stem at every growing stage due to high sugar content. common pest on roses are aphids which considered be major cause for product loss. Aphid infestations lead changes in plants, such as irregular holes petals, intact leaves devouring tissues. It hypothesized that different cut cultivars would have levels sensitivity or resistance...
