      abstract = {Papaya seedlings (cv.'Sunrise') were produced under  greenhouse conditions to determine the effects of  combinations of varying ethanol and gibberellic acid-3  (GA3) concentrations on papaya shoot height, leaf number,  leaf area, and shoot dry weight. Seedlings were grown in  0.5-L plastic containers filled with a potting medium  composed of 50% vermiculite, 30% periite, and 20% spaghnum  peat (v/v). When seedlings were 10 cm tall and had two-true  leaves, foliar sprays of ethanol (0, 5, 10, 15 or 20% v/v)  and G A3 (0, 10, 20 and 30 ppm w/v) combinations were  applied using a 5-mL solution volume. Treatments were  arranged in a randomized complete block design with seven  replications. Ethanol and GA3 concentrations interactively  influenced plant height (P<0.05). In all cases, as GA3 rate  increased there was an increase in plant height, regardless  of the ethanol concentration utilized. Although, plant  height increased when the 5% ethanol rate used (+13.7% for  0 GA3 treatments), higher alcohol concentrations caused a  rapid decline in height. Treatments had no effect (P>0.05)  on leaf number, whereas only ethanol rates affected papaya  leaf area, with maximum area obtained with 5% ethanol  (+32.6%). No significant ethanol by GA3 interactions  (P>0.05) were observed for shoot dry weight. However, both  factors individually influenced shoot dry weight. Leaf  area, plant height, and seedling dry weight was higher when  plants were treated with solutions containing 5% ethanol  than when other rates were used, yielding 42.6% higher  shoot dry weight than the untreated control. In fact,  plants receiving rates of 10% ethanol or higher had a dry  matter loss of at least 30% compared to untreated  seedlings.},
