UPTAKE AND DISTRIBUTION OF 3H-BA IN PEANUT LEAVES

Abstract:

The uptake of ³H-BA by leaf discs of peanut existed in two forms, active and passive forms, and the latter was about 60. 7% of total amount absorbed. When leaf discs were incubated with ³H-BA, the maximum amount of this chemical taken in was found after 2 hours and then decreased. A pH optimum at 7. 5 could benefit the ³H-BA uptake by leaf discs. At the range of 16- 26℃, the amount of BA absorbed by leaf discs was increased with temperature. When the leaves of decapitated-derooted peanut plants were smear...
