“…No presente trabalho, a porcentagem máxima de germinação foi de 77%, considerada alta se comparada aos resultados obtidos por outros autores (Scott & Ink, 1950;Ottenwaelter et al,1974;Pommer et al, 1988;Ergenoglu et al, 1997). Esta porcentagem de germinação foi alcançada, basicamente, pela combinação dos tratamentos com 4000 mg L -1 de GA 3 , corte da semente na região da micrópila e ambiente de germinação in vitro .…”

Breaking the dormancy of niagara rosada seeds without stratificationThe objective of this study was to asses the effect of three factors on the germination of grape seeds, cv. Niagara Rosada. The three studied factors were: physical treatments, chemical treatments and germination environment. The physical treatments consisted of whole seeds, seeds with a cross cut in the median region and seeds with a cut in the micropyle. The chemical treatments were applied by immersing whole seeds in aqueous solution of gibberellic acid (GA 3 ) with concentrations of 0 and 4000 mg L -1 . The environments evaluated were in vitro and ex vitro. The experiment was arranged in a factorial 3 x 2x 2, randomized blocks design, with 4 repetitions, each one consisting of a Gerbox® containing 25 seeds or a rack with 25 test tubes. The parameters evaluated were the percentage and speed of seed germination. The results showed that cutting is essential to the germination of non-stratified seeds. The combination micropyle cut, 4000 mg L -1 of GA 3 and in vitro environment resulted in 77% of seed germination. The in vitro environment was significantly superior to the ex vitro environment.

“…In grape seeds, dormancy is the main cause of low germination percentages (CELIK, 2001;WANG et al, 2009). In the search for methods to overcome dormancy in grape seeds, several authors have suggested cold stratification (BRASIL, 2009;WANG et al, 2009) along with exogenous application of gibberellic acid (GA 3 ) (ELLIS et al, 1983;ERGENOGLU et al, 1997;CELIK, 2001). However, in addition to not being effective in inducing germination in many seeds, these treatments require more than 120 days to produce normal seedlings.…”

In vitro germination to overcome dormancy in seeds of ‘Red Globe’, ‘Italia’ and ‘Niagara Rosada’ grapes

Dormancy in grape seeds slows the progress of many breeding programs of the crop, culminating in low uniformity and low germination percentages. Conventional methods used to overcome dormancy are time-consuming. Thus, in vitro seed germination emerges as a promising alternative to ensure the germination of grape seeds. In this study, we examined the in vitro germination and vigor of seedlings originating from seeds of ‘Red Globe’, ‘Italia’ and ‘Niagara Rosada’ grapes in growth media supplemented with five concentrations of gibberellic acid (GA3) (0, 1.41, 2.83, 4.24 and 5.66 µmol L-1) for 47 days. The use of GA3 increased seed germination percentage and seedling vigor, in the three varieties. Therefore, for the in vitro germination of seeds of ‘Red Globe’ can be used between 1.41 to 4.24 µmol L-1 of GA3. For ‘Italia’ grapes is indicated 1.41 µmol L-1 from GA3 and for ‘Niagara Rosada’ grape is as between 1.41 to 5.66 µmol L-1 from GA3 can be used.
