Plant Growth Regulators are organic substances whose low concentration modifies the physiological processes taking place in the plant. This modification of various reactions of the plant consists in supporting or inhibiting the processes of growth and development, such as, for example, germination, root formation, fruit setting and plant senescence. Plant growth regulators are used in a wide range, both in orchards and agricultural crops.
Plant growth regulators are used in particular to:
- prevent the lodging of cereal crops
- the rooting of cuttings
- stimulate fruit development
- regulate fruit maturation process
- fruit drop prevention
- prolong or interrupt the dormancy, e.g. of potato tubers
