EFFECT OF TREATMENT WITH GROWTH-REGULATORS AND SCARIFICATION ON THE TOLERANCE TO WATER-STRESS IN SEEDS OF ORYZA-SATIVA LCVIAC-165
(Inst Tecnologia Parana, 1994-01-01)
The effect of treatment of seeds of Oryza sativa L. cv. IAC 165 with gibberellic acid, 6-benzyladenine and ethrel on the tolerance to the water stress were analysed. Gibberellic acid had no effect and 6-benzyladenine and ...
Elevated atmospheric CO2 concentration increases rice blast severity
(2013-05-01)
The predicted atmospheric carbon dioxide concentration's increases are likely to alter plant-pathogen interactions. To assess the effects on rice blast, during three years (2007, 2008 and 2009), three rice cultivars (Agulha ...
