When the temperature either drops below the optimum range or surpasses, it can affect a plant's growth. The affect of temperature on plant growth is explored in this unit. Impact Increase water losses thought transpiration rate. All growth at the apical meristem is called primary growth which increases the height, not the width. Fruits were more sensitive to elevated temperature in their later stages of maturation. Resistant plants are used to restrict the growth and development of a specified pest and/or the damage they cause when compared to susceptible plant varieties under similar environmental conditions and pest pressure.
