FROST PROTECTION COVERS METHODS FOR AVOCADO IN DIFFERENT CULTIVARSABSTRACT -The experiment was carried out at EMBRAPA Technology Transfer Office at Canoinhas, Santa Catarina State, Northern Highland area. The aim was to evaluate the tolerance for low temperature in eight varieties of avocado (Choquette, Vitória, Herculano, Quintal, Linda, Tonnage, Fuerte and Ryan) planted in May of 2003 using two methods of covers for avocado maiden trees (eucalyptus branches and eucalyptus branches plus sombrite). In September, in the same year, the covers were removed and ranked by scores to evaluate the degree of frost injury on plants. There were no difference between avocado varieties in relation of covers methods. However, comparing the two covers methods, the use of eucalyptus branches plus sombrite was better than the use of eucalyptus branches, in young plants of avocado.
