Notes:
Gibberellic acid (GA3) 20 mg 1−1 and (2-chloroethyl) phosphonic acid (Ethephon) 10 mg 1−1 enhanced pollen tube length in Crotalaria juncea L. GA3 markedly increased the activity of amylase, acid phosphatase and β-glucosidase and enhanced leaching of amylase and acid phosphatase enzymes. The rise in the activity level and leaching of amylase and acid phosphatase after Ethephon treatment was comparatively less than that of GA3 and the response to Ethephon was restricted to the 45 and 90 min period of culturing. Ethephon did not affect the activity/leaching of β-glucosidase significantly. Actinomycin-D (Act.D) 25 mg l−1 and Cycloheximide (CH) 10 mg 1−1 reduced the tube growth as well as activity of these enzymes suggesting their de novo synthesis during pollen tube growth.
