Influência de bioestimulante no desenvolvimento de plantas de pepino japonês enxertadas e não enxertados em condições de ambiente protegido

The aim of this experiment was evaluate the effect of the bioestimulant administered in grafted and non-grafted japanese cucumber (Cucumis sativus L.) plants, under greenhouse conditions, in gas exchanges during the development of the plant and in the increase of yield. The experiment was carried out in the experimental area of Agronomic Sciences University of UNESP, Campus of Botucatu, São Paulo State, Brazil. The experiment design was completely randomized, in a factorial arrangement of 2x5, grafted and non-grafted plants and 5 treatments with bioestimulant: control, indolbutyric acid 0,0005% + citocinine 0,0009% + gibberelic acid 0,005% 250 mL ha-1; indolbutyric acid 0,0005% + citocinine 0,0009% + gibberelic acid 0,005% 375 mL ha-1; indolbutyric acid 0,0005% + citocinine 0,0009% + gibberelic acid 0,005% 500 mL ha-1; Yuca extract (Yucca elephantipes) + manganese + iron + copper + sulfur 375 mL ha-1 applied 15 days after the transplant, in intervals of 7 days between the applications, via leaf. The effect of the treatments were evaluated through the observations of the following characteristics: production of fruits (number and mass), average mass of the fruit and measures of gas exchanges. It can be concluded that indolbutyric acid 0,0005% + citocinine 0,0009% + gibberelic acid 0,005% 250 mL ha-1 increased CO2 assimilation rate and the water efficiency, influencing in addition to increase the quantity of the fruits

INHERITANCE of CUCUMBER TOLERANCE TO ZUCCHINI YELLOW MOSAIC VIRUS

Studies were carried out in Brazil to study the inheritance of tolerance to Zucchini yellow mosaic virus (ZYMV) in cucumber cv. Formosa. This cultivar was individually crossed with two cucumber lines from different varietal types (L(b) from a Brazilian type, and L(j) from a Japanese type), both susceptible to the virus. Two experiments, one for each line, were separately carried out, where 6 treatments (parents, generations F1, F2 and F1BC1 for both parents) were evaluated in a randomized block design with 5 repetitions. Cotyledons of 2-week-old cucumber seedlings were inoculated with ZYMV. Only the plants that did not show symptoms up to 63 days post inoculation were considered as tolerant. A chi-square (chi(2)) analysis for assessing segregation from F2 and both F1BC1, led to the conclusion that the tolerance found in cv. Formosa is determined by a recessive gene.

Experimental Infection of Culex Annulirostris, Culex Gelidus, and Aedes Vigilax With a Yellow Fever/Japanese Encephalitis Virus Vaccine Chimera (Chimerivax TM-JE)

Australian mosquitoes from which Japanese encephalitis virus (JEV) has been recovered (Culex annulirostris, Culex gelidus, and Aedes vigilax) were assessed for their ability to be infected with the ChimeriVax-JE vaccine, with yellow fever vaccine virus 17D (YF 17D) from which the backbone of ChimeriVax-JE vaccine is derived and with JEV-Nakayama. None of the mosquitoes became infected after being fed orally with 6.1 log(10) plaque-forming units (PFU)/mL of ChimeriVax-JE vaccine, which is greater than the peak viremia in vaccinees (mean peak viremia = 4.8 PFU/mL, range = 0-30 PFU/mL of 0.9 days mean duration, range = 0-11 days). Some members of all three species of mosquito became infected when fed on JEV-Nakayama, but only Ae. vigilax was infected when fed on YF 17D. The results suggest that none of these three species of mosquito are likely to set up secondary cycles of transmission of ChimeriVax-JE in Australia after feeding on a viremic vaccinee.
