Raspberries (Rubus spp) are temperate climate fruits with profitable high returns and have the potential for diversification of fruit growing in mid to low-latitude regions. However, there still no cultivars adapted climatic conditions pressure diseases that occurs tropical areas. In this context, our objective was evaluate genetic diversity from a 116 raspberry genotypes panel obtained interspecific crosses testcross scheme four already introduced Brazil. The genotyped via...

Although Brazil is the largest fig (Ficus carica L.) producer in Southern Hemisphere, it mainly uses only one cultivar, 'Roxo de Valinhos'. In addition, propagation almost entirely through hardwood cuttings. Therefore, aim of this study was to establish a method that provides more successful rooting stem segments cultivars for purpose expanding genetic base tree. The used were 'Brunswick', 'Calabacita', 'Negro Bursa', 'Mini Figo', 'Lampa Preta', 'Lemon', 'Troiano',' Nazaré', 'Três num...

Pear ( Pyrus spp.) is a temperate-climate fruit species that has gametophytic self-incompatibility. Cross-pollination among intercompatible cultivars can be useful in selecting for breeding programs. The objective of the present study was to evaluate effective fruiting from cross-pollination between hybrid pear and characterize tree S-alleles. Seven were evaluated: Cascatense, Centenária, D’água, Primorosa, Seleta, Tenra, Triunfo. Controlled crosses carried out two seasons consisted...

Late leaf rust (Thekopsora americana) is a disease that affects raspberry (Rubus idaeus L.), leading to decrease in production. The adoption of precise criteria for quantification helps decision-making its management. A diagrammatic scale (DS) useful tool quantifying severity the field. DS was developed and validated this study estimate late leaves. defined with eight levels (0.2, 0.4, 0.9, 2.2, 5.1, 11.5, 23.9 43.2%). validation performed by 15 untrained raters two steps, without using DS....

O caquizeiro é propagado por enxertia, em porta-enxertos obtidos sementes. Devido à baixa germinação, este trabalho teve como objetivo aumentar a obtenção de dos caquizeiros Dyospyros kaki e lotus através da estratificação tratamento das sementes com ácido giberélico utilização diferentes temperaturas ambientais. No primeiro experimento, as foram colocadas entre camadas areia umedecida placas Petri mantidas câmara tipo B.O.D. temperatura 4 ºC, 15 30 dias, além do controle, onde imersas água...

ABSTRACT: The persimmon tree is propagated by grafting and the rootstocks are produced from seeds. Grafting done in July, which coincides with time when trees pruned. But, at this time, many not yet eligible to receive grafts. In case budsticks/cleft storage an option. Thus, study aimed verify feasibility of cold method promote better graft development. Rootstock was sown August 2012 branches were collected July 2013. Part used for (budding cleft methods) one-year old other part stored low...
