Effect of Gibberellic Acid on Seed Germination and Seedling Growth Behaviour in Three Desert Tree Species

The present study was undertaken to assess the effect of different concentrations of gibberellic acid treatment on germination and seedling growth behaviour value in Albizzia lebbeck, Acacia nilotica and Prosopis cineraria. The results of the study clearly indicated that the seed germination and growth rate hastened to maximum by the application of 750ppm GA3 for 24hrs, indicated thereby that as the concentration increased, growth behaviour increases. The maximum growth attributes value was obtained at 750ppm in Acacia nilotica.
