Question

What is the optimal temperature range for pollen tube growth in most flowering plants?

विकल्प

• [10-20°C]

• [0-10°C]

• [30-40°C]

• [20-30°C]

Answer 1

The optimal temperature range for pollen tube growth in most flowering plants is between 20 and 30 degrees Celsius. Temperatures outside this range may significantly slow down or inhibit pollen tube growth, affecting successful pollination and fertilisation.
