Abstract:

The lowest pods on common bean (Phaseolus vulgaris) are on or near the ground. Yields may improve by raising these pods to reduce yield loss, especially with direct harvest. The objective of this field study was to use gibberellic acid (GA3) to raise lower pods and increase yield. Seeds of cultivars Poncho (Type III, pinto) and Matterhorn (Type II, great northern) were dipped in GA3 at 0, 125, 500, and 2000 ppm and planted in 30-inch rows (2005). Stem elongation was promoted, but emergence and yield were decreased especially for ‘Poncho’. In foliar tests in 30-inch rows (2005 and 2006), GA3 wa

Abstract:

Four year old `Loring' peach trees on `Lovell' rootstock were treated with single applications of 0, 50, and 100 ppm GA3 alone and in combination with 100 ppm ethephon on 15 November 1988, 1989, and 1990 to determine the effect on bloom delay the following spring. Flower bud number was not affected by any of the treatments the next spring. Ethephon had the greatest effect on bloom delay the following spring. The 50 and 100 ppm GA3 treatments resulted in a slight delay of bloom. The combination of 50 and 100 ppm GA3 and 100 ppm ethephon resulted in less of a bloom delay than ethephon alone but

Abstract Injection of gibberellic acid (GA3) into crowns of field grown rhubarb (Rheum rhaponticum) stimulated early petiole growth and increased total and marketable yields. The GA3 treatment was most effective in late January and February, less effective in early March, and ineffective in June. Growth was stimulated by injection of 2.5 to 40 mg GA3/crown, with 10 to 20 mg sufficient for optimal growth. Spray applications of GA3 to soil-free buds and application through a trickle irrigation system did not increase rhubarb yield or earliness. Costs for the GA3 injection treatment are very favo

The development of cotton fibre was divided into four distinct growth phases but overlap between elongation and secondary thickening was considerable which suggests that both these phases are independent of each other. During fibre elongation, GA3 content remained low and increased after a decrease in the rate of fibre elongation in all three genotypes. The long

In greenhouse and field studies, benzyladenine (BA) and gibberellic acid (GA3) applied together as a foliar spray increased runner production in dayneutral strawberries (Fragaria ×ananassa Duch.) but not when applied separately. Runner production increased linearly with increased BA concentration to 1800 mg·L–1. At high dosages, GA3-treated plants produced elongated internodes that, in the field, led to fewer daughter plants. In Florida, daughter plants derived from plants sprayed with the growth regulators increased yield by up to 10% in fruiting experiments. To induce runnering in the field

Abstract Multiple applications (1-3) of 10 and 50 ppm GA3 to ‘Bing’ and ‘Lambert’ (Prunus avium L.) sweet cherries increased fruit firmness and weight, and delayed harvest. Firmness was positively related to dose of GA3 (number of applications × concentration), soluble solids (SS), and In leaf/fruit ratio. GA3 interacted with SS so that the effect of GA3 dose on firmness was increased at higher SS levels. Fruit coloring was delayed by GA3. Chemical name used: gibberellic acid (GA3).

Abstract:

Field and container experiments were conducted in the Dominican Republic to determine the effect of gibberellic acid 3 (GA3) rates on papaya ringspot virus (PRSV)-infected seedlings and adult plants of `Cartagena Ombligua' papaya. The apical region of PRSV-infected and PRSV-uninfected plants was sprayed with GA3 aqueous solutions at rates 0, 25, 50, 75, and 100 ppm. PRSV-uninfected adult plants and seedlings produced longer internodes as GA3 rates increased. Adult PRSV-uninfected plants flowered normally at any GA3 rate. PRSV-infected seedlings and adult plants also responded to GA3 sprays, bu
