Nocturnal Fanning Suppresses Downy Mildew Epidemics in Sweet Basil
Downy mildew is currently the most serious disease of sweet basil around the world. The oomycete causal agent Peronospora belbahrii requires ≥ 4h free leaf moisture for infection and ≥7.5h of water-saturated atmosphere (relative humidity RH≥95%) at night for sporulation. We show here that continued nocturnal fanning (wind speed of 0.4-1.5 m/s) from 8pm to 8am dramatically suppressed downy milde...
متن کاملEssential oils from sweet basil (Ocimum basilicum) as novel enhancers to accelerate transdermal drug delivery.
The purpose of this study was to evaluate the essential oils from sweet basil (Ocimum basilicum, OB) as skin permeation enhancers to promote the percutaneous absorption of drugs. The in vitro and in vivo irritancy of the essential oils was also examined. Terpenes with various carbon numbers (mono-, sesqui-, di-, and tri-) were identified in both the lower-polarity fraction (OB-1) and higher-pol...
متن کاملA first linkage map and downy mildew resistance QTL discovery for sweet basil (Ocimum basilicum) facilitated by double digestion restriction site associated DNA sequencing (ddRADseq)
Limited understanding of sweet basil (Ocimum basilicum L.) genetics and genome structure has reduced efficiency of breeding strategies. This is evidenced by the rapid, worldwide dissemination of basil downy mildew (Peronospora belbahrii) in the absence of resistant cultivars. In an effort to improve available genetic resources, expressed sequence tag simple sequence repeat (EST-SSR) and single ...
متن کاملThe content of essential oil in ten sweet basil (Ocimum basilicum L.) cultivars and its composition
The experiment was conducted in the Research Institute of Medicinal Plants in Poznań, Poland in 2005–2006 and concerned a collection of ten sweet basil cultivars such as: ‘Minette’, ‘Mittelgrossblättriges Grünes’, Piccolino’, ‘Rubin’, ‘Red Rubin’, ‘Genoveser’, ’Martina’ and two Polish cultivars: ‘wala’ and ‘Kasia’. Moreover, ‘Lemonette’ cultivar of Ocimum americanum L. was also included in the ...
متن کاملChicoric acid found in basil (Ocimum basilicum L.) leaves
This is the first report to identify the presence of chicoric acid (cichoric acid; also known as dicaffeoyltartaric acid, which is a caffeic acid derivatizedwith tartaric acid) in basil leaves. Rosmarinic acid, chicoric acid and caftaric acid (in the order of most abundant to least; all derivatives of caffeic acid) were identified in fresh basil leaves. Rosmarinic acid was themain phenolic comp...
