Spray application factors and plant growth regulator performance: II. Foliar uptake of gibberellic acid and 2,4-D
Effects of droplet size and carrier volume on foliar uptake and translocation of gibberellic acid (GA3) and 2,4‐D were investigated. Simulated spray droplets were applied to primary leaves of 10‐day‐old Phaseolus vulgaris (cv Nerina) in droplet sizes and carrier volumes ranging from 0.5 to 10 μl and...

description | Effects of droplet size and carrier volume on foliar uptake and translocation of gibberellic acid (GA3) and 2,4‐D were investigated. Simulated spray droplets were applied to primary leaves of 10‐day‐old Phaseolus vulgaris (cv Nerina) in droplet sizes and carrier volumes ranging from 0.5 to 10 μl and 10 to 200 μl per leaf, respectively. Doses of GA3 (2 μg per leaf) and 2,4‐D (100 μg per leaf) were held constant. Total uptake of GA3 approached a penetration equilibrium within 24 h after application, but uptake of 2,4‐D continued to increase. Decreasing droplet size and/or increasing carrier volume increased GA3 and 2,4‐D uptake.
Translocation to stem and roots was positively related to total uptake. A positive linear relationship between the logarithm of the total droplet/leaf surface interface area and 2,4‐D uptake or translocation was found, but for GA3 this relationship was quadratic. Potential mechanisms of the effects of spray application factors on foliar uptake are discussed.
