Influence of the time of year on the development of symptoms in ‘Grande naine’ plants artificially inoculated with Mycosphaerella fijiensis in a cultivation house
Journal Title: Biotecnología Vegetal - Year 2011, Vol 11, Issue 1
Abstract
Plant pathogen fungi required favorable conditions to invade and colonize plant tissues, which may change according to the season of the year. This work is aimed to evaluate the influence of different seasons (June- August and August-October) in the development of symptoms in ‘Grande naine’ artificially inoculated with Mycosphaerella fijiensis in greenhouse. Inoculation assays were done during three consecutive years (2005, 2006 and 2007). None differences in attack intensity between different seasons were observed, at 14, 21, 35, 49 y 63 days post inoculation (dpi). This shows that the development of symptoms in greenhouse was similar in the period from June to October. Temperature and humidity have not been controlled by all laboratories that conduct studies related to M. fijiensis. Then, to choose the appropriate season for artificial inoculations is a prerequisite for effective development of M. fijiensis infective cycle and to avoid masking in the phenotype of resistance.
