Question

All phytohormones are PGR but all PGR are not phytohormones why​

Answer 1

Answer:

Explanation:

• All Phytohormones are the PGR, but all PGR are not phyto hormones because they are not planting growing systems hence all PGRS are not planted growth regulators which will phyto hormones the plant and helps them to grow in a good manner.
• A growth maker or we can call PGR or the plant growth regulator which is a synthetic or natural or the chemical which is to be sprayed or to spray to the plant or the seeds for altering its characteristics.

Answer 2

Plant growth regulators (PGRs) are chemicals that are used to modify plant growth by increasing branching, suppressing shoot growth, increasing return bloom, removing excess fruit, or changing fruit maturity. Phytohormones are chemical messengers that coordinate cellular activities.

Plant growth regulators:

• Plant growth regulators (PGRs) are compounds that are used to manipulate plant growth by boosting branching, limiting shoot growth, increasing return bloom, eliminating surplus fruit, or changing fruit maturity.
• Plant hormones are classified into five groups: auxins, gibberellins, cytokinins, abscisic acid (ABA), and ethylene.
• They collaborate to coordinate cell growth and development.
• They are chemical messengers that allow intracellular communication to take place.
• These are also referred to as plant hormones.

Phytohormones:

• Plant hormones (phytohormones) are compounds that plants create to control their growth, development, reproductive activities, longevity, and even death.
• These tiny compounds are produced by secondary metabolism and are responsible for plant response to environmental cues.
