- A puncture was made on leaves of intact plants grown for 2–3weeks in a greenhouse; the sample was then dissolved in 20 μg/μl of water and applied to the puncture. After incubating for 72 h in the greenhouse, the extent of the lesion was assessed.
- Twenty five germinated lettuce seeds (Grand Rapids Waldmann) were placed on filter paper (3.4 cm diameter in petri dishes) soaked with each test solution (500 μl). Each dish was kept in a dark chamber at a temperature of 25°C, and after a 20 h incubation, the root lengths were measured. Growth inhibition was calculated as a percentage of the average length of roots of the treated plant to that of the control in deionized water.
