Abscisic acid and ethephon treatments applied to ‘Verdejo’ white grapes affect the quality of wine in different ways Scientia Agricola
González,Raquel; González,María-Rosa; Martín,Pedro.
ABSTRACT: Exogenous ethephon and abscisic acid (ABA) treatments are used worldwide to improve the coloring of red table grapes, but there is little information about their impact on the quality of white grapes and wines. The aim of this work was to evaluate the effects of exogenous ethephon and ABA applications at veraison on the composition of ‘Verdejo’ white grapes, and on the quality of their wines. To attain this objective, a field trial was carried out in a ‘Verdejo’/110 Richter vineyard located in north-central Spain. Two levels of ethephon (0 and 1500 mg L−1) and ABA (0 and 800 mg L−1) were sprayed on clusters at veraison, in a factorial design for three consecutive seasons. Ethephon and ABA had additive effects, decreasing titratable acidity and...

Roesler,Eduardo André; Manfroi,Ernandes; Morás,Andréa; Didoné,Dielli Aparecida; Grando,Magali Ferrari; Lau,Elene Yamazaki.
ABSTRACT: The availability of an efficient protocol for in vitro regeneration is imperative for genetic transformation. Using genotypes adapted to the target region as a transgenic platform accelerates the development of cultivars. Therefore, this study aimed to adapt an in vitro regeneration protocol for Brazilian wheat genotypes. For this purpose, the in vitro regeneration capacity of immature embryos from six Brazilian wheat genotypes using two protocols of regeneration of somatic embryos was analysed. Furthermore, combinations of 2,4-D and picloram in the callus induction medium were tested in order to improve regeneration efficiency. Genotypes with higher regeneration efficiency were BR18-Terena and PF020037, yielding 0.42 and 1.13 shoots per explant...

Brasileiro,Ana Christina Rabello; Willadino,Lilia; Carvalheira,Gianna Griz; Guerra,Marcelo.
Different growth regulators combinations were tested on the production of anther callus in tomato cultivar IPA 5. Calli were induced on media supplemented with 1.0mgL-1 gibberellic acid (GA3), 0.05mgL-1 alpha-naphthaleneacetic acid (NAA) plus 0.1mgL-1 6-benzylaminopurine (BAP), or with 1.0mgL-1 BAP plus 1.0mgL-1 NAA. The medium containing 1.0mgL-1 BAP and 1.0mgL-1 NAA produced the highest calli frequency, and promoted plant regeneration by indirect organogenesis, when calli were transferred to 0.01mgL-1 BAP and 0.001mgL-1 NAA. Plants regenerated presented tetraploid cells and rare diploid cells. These tetraploid plants could be used as source for further obtainment of trisomic lines, for the purpose of genic localization studies and protein compounds...
