| ABSTRACT Through in vitro tissue culture techniques it is possible to propagate high quality nursery plants faster. Cryotherapy is a promising tool, based on in vitro culture techniques, for achieving in a short time, high frequency of regenerating plants free of viruses. The objective of this review is to present and analyze the results of research conducted in cryotherapy methods based on cryopreservation protocols for recovery of cultivars free of micro-organisms with potential agronomic interest. The main methods employed in cryotherapy are encapsulation-dehydration, vitrification, encapsulation-vitrification and droplet vitrification, which are based on the immersion of preconditioned shoot tips in liquid nitrogen, followed by their recovery in vitro... |

| RESUMO O objetivo do trabalho foi estimar a soma térmica e o filocrono de quatro cultivares e duas ‘seleções’ de morangueiro para o Planalto Sul- Catarinense. O experimento foi conduzido no Centro de Ciências Agroveterinárias, na Universidade do Estado de Santa Catarina. Foram utilizadas duas seleções de morangueiro em avançada fase de estudos, denominadas ‘SEL1’ e ‘SEL2’, utilizando mudas provenientes de um programa público de melhoramento genético da Itália e quatro cultivares: Camino Real e Camarosa, provenientes do Chile, e San Andreas eAlbion, provenientes da Argentina. O transplante das mudas foi realizado em 26-06-2012. O delineamento experimental utilizado foi o de blocos ao acaso, com três repetições, cada repetição composta de oito plantas, sendo... |

| ABSTRACT The aim of this study was to evaluate the efficacy of metamitron or metamitron plus benzyladenine as a post-bloom thinner on ‘Baronesa’ and ‘Fuji’ apples. Three experiments (rate, timing and BA combination) were conducted during two crop seasons, 2013/14 and 2014/15 at the experimental station located in Caçador, SC. Fruit set, fruit drop, yield per tree, fruit size and flowering return were assessed. The efficacy of metamitron was affected by time of application, and when applied at petal fall, promoted the proper adjustment of the production load of plants. Yield per plant reduces, whereas the allocation of fruits in categories of greater size increases proportionally to the increase in the metamitron concentration applied. However, there is... |
