“…It is worth marking that similar results were received in next years. The results obtained corroborate those of Funnell et al (1992), who had achieved a substantial increase in the flower yield of cv. Galaxy on application of Promalin.…”

To assess the effect of a mixture of benzyladenine and gibberellic acid on the quality and yield of flowers and leaves of cvs Albomaculata, Black Magic and Mango, their tubers were soaked before planting for 30 min in a water solution with 100-600 ppm BA and 150 ppm GA 3 . The BA + GA 3 mixture application resulted in 2.5-3.5 times as many flowers in comparison to the control plants, which did not affect the quality of flowers and the yield of leaves. The leaves, however, showed higher greenness index and protein quantity.

“…In the light of the research done, gibberellic acid is proved to be an effective (Funnell, Tjia 1988;Corr, Widmer 1991;Funnell et al 1992;Denis et al 1994;Janowska, Krause 2001;Janowska, Schroeter 2002;Janowska, Zakrzewski 2006). Nonetheless, the increase in the yield depends on the cultivar and there are more than 120 recognized cultivars.…”

“…The contrasting effect of GA 3 application on flowering and organ elongation has been reported previously Widmer, 1987, 1991;Funnell et al, 1992). In gibberellin-treated plants, strong enhancement of floral stem differentiation versus lack of the effect on the elongation of inflorescence peduncles and leaves was observed.…”

Involvement of gibberellin in the regulation of size and shape of different plant organs (leaf, floral stem, and tuber) were studied in colored Zantedeschia cv. 'Calla Gold' (CG). The effect of gibberellin on allometric relationships between these organs was also examined. Tubers were dipped in solutions of GA 3 (0.6 mM) or of the gibberellin biosynthesis inhibitor Uniconazole (3.4 mM) prior to storage, prior to planting, or twice-before storage and before planting. The effects of the growth regulators were followed in plants grown in pots in a screen house under 50% shade. Tuber weight was reduced by both GA 3 and Uniconazole, but by different processes. GA 3 increased the number of the floral stems per plant, but did not affect floral stem length or blade and petiole length. Uniconazole reduced the proportion of flowering plants, and inhibited leaf and stem elongation. Co-application with GA 3 canceled the inhibitory action of Uniconazole on leaf and peduncle elongation. This suggests that gibberellin is involved in the regulation of organ elongation, despite lack of direct effect of exogenous GA 3 application. Linear positive relationships were found across the different treatments between tuber weight vs. leaf area, petiole length vs. blade length, petiole length vs. floral stem length, and blade length vs. floral stem length. The constancy in size relationships suggests that the action of the growth regulators on the growth of the different organs were according to intrinsic allometric relationships among them. The differential action of GA 3 on flowering and on stem and leaf elongation is discussed.

Bioestimulante na promoção da brotação em estacas de raiz de amoreira-preta

et al. 2012

RESUMO-Este trabalho objetivou verificar o efeito do bioestimulante Promalin® na promoção da brotação em estacas radiciais de amoreira-preta (Rubus spp.) cv. Brazos. O experimento foi conduzido de janeiro a março de 2010, sendo o delineamento inteiramente casualizado, com cinco concentrações de bioestimulante, na forma de solução: T1= 0 mg L -1 ; T2= 10 mg L -1 ; T3= 20 mg L -1 ; T4= 40 mg L -1 , e T5= 80 mg L -1 , sendo as estacas radiciais mergulhadas nessas soluções durante 12 horas, em sete repetições com dez estacas cada. Após 75 dias, foram avaliadas: a emergência de brotos, o número de estacas brotadas, número de brotos, número de folhas, comprimento da haste principal e porcentagem de sobrevivência das brotações, além da análise de carboidratos solúveis. Ocorreu evolução gradativa ao longo do tempo na emergência das brotações, iniciando em aproximadamente sete dias após o plantio. As maiores concentrações de Promalin® inibiram a brotação em estacas de raiz, e as características de desenvolvimento dessas brotações foram alteradas, sendo os melhores resultados alcançados sem a aplicação dos reguladores vegetais. termos para indexação: Rubus spp., multiplicação, pequenos frutos, regulador vegetal. BIOSTIMULANT IN PROMOTING THE SPROUTING IN ROOT CUTTINGS OF BLACKBERRYABSTRACT-This study aimed to evaluate the effect of biostimulante Promalin® promoting sprouting in root cuttings of blackberry (Rubus spp.) cv. Brazos. The experiment was conducted from January to March 2010, with a completely randomized design with five concentrations of biostimulant, as solution: T1= 0 m g L -1 , T2= 10 mg L -1 , T3= 20 mg L -1 , T4= 40 mg L -1 and T5= 80 mg L -1 with the root cuttings dipped in these solutions for 12 hours and seven replications, and the plot compose by ten root cuttings. After 75 days were examined: the emergence of shoots, number of sprouting, shoot number, leaf number, length of main stem and survival percentage of the shoots, besides the analysis of soluble carbohydrates. Gradual evolution has occurred over time in the emergence of the shoots, beginning in approximately seven days after planting. The highest concentrations of Promalin® inhibited the sprouting of root cuttings and the growth characteristics of these shoots, the best results were achieved without the application of the product.
