Are tomato plants photoperiod?
In tomato, extended photoperiod principally favored shoot development. On a daily basis, tomato plants exposed to extended light periods accumulated more carbohydrates than pepper plants. Tomato plants had 4.4–4.9 times more hexoses than sucrose whereas this ratio was only 1.1–1.5 in pepper plants.
Is maize a long day plant?

Is rice a long day plant?
Rice is a short-day plant; flowering (termed “heading” in rice and other cereals) is promoted by short daylength. However, there is a large degree of genetic variability in this trait among rice cultivars, from photoperiod insensitivity to strong photoperiod sensitivity.
Is cucumber long day plant?
Generally, long-day plants flower in the summer and short-day plants flower in the spring or fall. Day-neutral plants form flowers independent of day length. These plants, such as cucumber, tomato, pea, corn, sunflower, and dandelion, simply begin flowering once they have reached a certain age.
Do my porch light bother my tomato plants at night?
