Research identifies protein that signals flowering in squash plants
...ort day (SD) plants require a short day length (or more
precisely, a long night) in order to flower. These are plants that flower as the days grow shorter, such as in the fall in temperate regions. Long day (LD) plants will flower when nights are short (and days are long), and typically flower in late spr...
