Adaptations of Plants to Environmental Factors: light variations, Temperature variations, Thermoperiodism, and Vernalization For Class 10th, 11th, and 12th
(I) Short-Day Plants, which only develop and reproduce normally when the photoperiod is less than a critical maximum (12–14 hrs), like Cannabis sativa, Andropogon virginicus, and Datura stramonimum,
(II) long-Day Plants, develop and reproduce normally when the photoperiod is greater than a critical minimum (12–14 hrs). Long-day plants, like Brassica rapa and Sorghum vulgar, are those whose growth and reproduction are boosted by day lengths greater than the critical day length.
(III) Day-Neutral plants since they don’t care about the duration of the photoperiod. such as Cucumis, Poa,
