Which of the following statements about growth retardants is TRUE?

🔑Key Points:
-Growth retardants work by interfering with hormonal processes that control cell division and elongation. These processes are most active in young, growing tissues.
-Their effects are not permanent; once the retardant wears off, the plant can resume normal growth.
-Different plant species and even different cultivars within a species can vary in their sensitivity to growth retardants.
-Growth retardants can have other effects on plant metabolism, such as altering photosynthesis and nutrient uptake.
