Influence Of Environmental Stressors On Plant Growth Plasticity Of Mimosa Pigra Towards Changes Of Soil Chemical Properties

The succession of invasive plants species is mostly facilitated by certain adaptive morphological and physiological traits. The establishment of Mimosa pigra seedling at early growth period, particularly in stressful environment is most crucial for the naturalization of this species. This species is...
