Forest tree seedlings growth as influenced by plant growth regulators in nursery

A study was conducted to see the effect of plant growth regulators on growth of different forest tree seedlings in nursery with the aim to produce good quality planting stock for plantation in the field. Pooled results of two years indicate that Vipul and Mixtalol applied @ 2 ppm as foliar spray on foliage at 45 and 90 days after sowing of seeds in polybags recorded maximum growth in terms of height and collar diameter of all tree species viz Parkinsonia aculeata, Acacia senegal, A bivinosa, A salicina, A holosericea, A leucophloea, Prosopis cineraria and Leucaena leucocephala which was significantly higher over control.
