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 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 کاملLight Quality Dependent Changes in Morphology, Antioxidant Capacity, and Volatile Production in Sweet Basil (Ocimum basilicum)
Narrow-bandwidth light treatments may be used to manipulate plant growth, development and metabolism. In this report LED-based light treatments were used to affect yield and metabolic content of sweet basil (Ocimum basilicum L. cv "Ceasar") grown in controlled environments. This culinary herb produces an aroma highly appreciated by consumers, primarily composed of terpenes/terpenoids, phenylpro...
متن کاملDaytime Solar Heating Controls Downy Mildew Peronospora belbahrii in Sweet Basil
The biotrophic oomycete Peronospora belbahrii causes a devastating downy mildew disease in sweet basil. Due to the lack of resistant cultivars current control measures rely heavily on fungicides. However, resistance to fungicides and strict regulation on their deployment greatly restrict their use. Here we report on a 'green' method to control this disease. Growth chamber studies showed that P....
