Abstract
The effect of temperature on uptake of C-14-labeled NAA was determined using detached apple leaves. Uptake by both adaxial and abaxial surfa ces was measured at 15 and 35C over a 24-hour period, Foliar absorptio n of NAA by the abaxial surface was greater than that by the adaxial s urface. Absorption by the abaxial surface increased linearly (P < 0.00 1) with temperature over the range of 15 to 35C. These results are dis cussed in relation to fruit thinning. Chemical name used: 2-(1-naphthy l)acetic acid (NAA).
