Influence of plant age, chilling hours and genotype on the number of new shoots...
Viegas Oliveira, J.; Oliveira, C. M.; Luz, F.R.; Oliveira, P.B.Little is known about the factors affecting vegetative propagation of raspberry plants by root buds to maximize plant production in the nurseries. The number of buds in the roots that can produce suckers is cultural (planting date, cane density, soil type, moisture, etc.) and climatic (temperature and photoperiod) dependent. Plant age is a factor that influences root system weight as a longer time for root deve...
Effect of plant density in long-cane blackberry winter production
Dias Santos, I.; Oliveira, C. M.; Oliveira, P.B.Blackberry production in Portugal is increasing mainly in the winter months due to the higher off-season prices. In order to produce fruit in this period growers need to use long-canes. This is a new production system used with great success in raspberries but little is known about its adaptation to the blackberry. Blackberries are plants with a high vegetative growth and nurseries often send to grower plants d...
Study of flower bud differentiation and development to improve strawberry produ...
Palha, M.G.; Valdiviesso, T.; Oliveira, C. M.; Oliveira, P.B.In order to extend out-of-season strawberry production in protected culture it is common to use plants with pre-formed flower buds to increase yield. This study aimed to characterize the flower bud differentiation in different commercial plant types and to examine the dynamic of the flowering throughout fall, winter and spring production in short-day (SD) and day-neutral (DN) strawberry cultivars. Experiments w...
Sperm bundles in the seminal vesicle of the crematogaster victima (Smith) adult...
Oliveira, C. M.; Lino-Neto, J.; Moreira, J.; Gomes, L. F.; Camargo-Mathias, M. I.This study establishes the presence of spermatodesm in the seminal vesicles of sexually mature males of Crematogaster victima (Smith). In this species, the spermatozoa are maintained together by an extracellular matrix in which the acrosomal regions are embedded. This characteristic has not yet been observed in any other Aculeata. However, the sperm morphology in this species is similar to that described for ot...
Fitness costs associated with low-level dimethoate resistance in Phytoseiulus m...
Oliveira, C. M.; Rezende, D. D. M.; Fadini, M. A. M.; Melo, J. W. S.; Guedes, R. N. C.; Pallini, A.; Oliveira, H. G.Phytoseiulus macropilis Banks (Acari: Phytoseiidae) is an effective predator of tetranychid mites, but there are no data on its response to pesticides. We investigated the resistance of the predatory mite P. macropilis to the acaricides abamectin and dimethoate, and we examined the fitness costs associated with resistance. Two populations were tested: one from conventional cultivation and another from an area n...
Composição florística e faunística de quintais agroflorestais da agricultura fa...
Quaresma, A. P.; Almeida, R. H. C.; Oliveira, C. M.; Kato, O. R.Os quintais agroflorestais são comuns entre os agricultores familiares da Amazônia, sendo sistemas de uso da terra sustentáveis desenvolvidos a partir dos saberes tradicionais. Além de ter como principal finalidade a promoção da segurança alimentar, são espaços de socialização e lazer para os agricultores e, podem contribuir para a composição de sua renda pela venda do excedente da produção. O objetivo desse tr...
