Question

Role of physiological growth parameters in crop productivity

Answer 1

• Fundamental processes such as photosynthesis, respiration, plant nutrition, plant hormone functions, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed germination, dormancy and stomata function and transpiration, both parts of plant water relations, are studied by plant physiologists.

Answer 2

Physiological growth parameters in crop productivity and their role:

Proper plant growth leads to better crop productivity and also enhance a better yield during the harvest period. This also helps to improve the economic condition of farmers.

Certain physiological growth parameter are:

• Respiration
• Plant hormone
• Plant hormone activity
• Photosynthesis
• Photoperiodism
• Photo morphogenesis
• Circadian rhythms
• Environmental stress physiology
• Seed germination
• Dormancy, transpiration rate
• Stomata function
• Soil fertilizer enrichment
• Harvest Index
• Water use efficiency
• Nutrient use efficiency
• Assimilate partitioning
• Aerobic content.

The above parameter influence the plant growth in systematized way.
