What is a shortday plant and a long day plant ?

Question

please explain the difference , and explain what they do,

also give a list of SHORT DAY PLANTS

Answer 1

1. Short?day plants will be induced to flower only when the day- length is below a certain critical length. If the critical day-length is exceeded, the plant remains in a vegetative state. The critical day-length varies among species and cultivars. Examples are chrysanthemums, poinsettias and Michalmas daisy.

2. Long?day plants will be induced to flower only when the critical day-length is exceeded. Until the day-length exceeds the critical length, vegetative growth continues. As with the short?day plants, the critical day-length varies both among and within species. Examples are spinach, beet, and radish.
