rooting: Rooting (success/failure) of plants in a 3-factorial field trial

Description

Part of an experiment on propagation of plant genera Acer and Pyrus. Cuttings were taken from motherplants of age 5 and age 20, from top or base, and were treated with 0, 0.5 and 2 percent IBA to induce rooting. Treatments were arranged in a completely randomized design, among other variables, the number of cuttings with and without roots was recorded.
