The effect of light stress and water stress on growth rate in Mentha arvensis

The effect of environmental stresses on growth rate was tested for Mentha arvensis (Mint). The plant was planted under different light intensity and watered either within 2 days interval, 4 days interval or 6 days interval. The stresses were monitored to see the significant effect on its physiological parameters and to test the adaptability of Mentha arvensis toward those stresses. The aim of this study is to measure the growth rate of Mentha arvensis affected by the combination of light and water stress. The findings of this study showed that plant that received less amount of nutrient and sources will try to develop self-mechanism, such plant tends to elongate its roots searching for water access. Through self-mechanism development, plant was able to absorb more nutrient effectively as both light and water act as a main source in providing morphological adaptive strategy for environmental stresses.
