Abstract
The effects of simulated herbivory on different leaf ages on the growth and development of individually potted mungbean plants, Vigna radiata L. Wilzeck, were studied by imposing three leaf damaging treatments: simulated young (Sy), simulated mature (Sm), and simulated old (So), plus control (C). In general, the results revealed the strong influence of herbivory or damage to the leaf on the plant's growth and development. Specifically, damaging or puncturing of the leaves regardless of leaf age decreased the aboveground biomass and the number of seeds per pod. Simulated herbivory on the young-age-class caused a decrease in the plant's height and length of pods. Simulated herbivory on mature leaves decreased leaf production but increased seed weight as compared to those of Sy and So plants. No effect on the number of days to flowering, on the weight of pods and on the seed viability were observed in relation to the damage. Further studies are recommended on field-grown mungbean to determine economic levels of herbivory since leaf damage cannot be entirely prevented.
