The red colour of tomato is due to Pigment lycopene.
Lycopene is the red-colored pigment abundantly found in red-colored fruits and vegetables such as tomato, papaya, pink grapefruit, pink guava and watermelon. This red-colored pigment was first discovered in the tomato by Millardet in 1876.
Fresh tomatoes contain anywhere from 0.88 - 7.74 mg lycopene/100 g wet weight.

Calcium deficiency in tomato causes BER and fruits with BER have Ca level of > 0.2%.
BER is Blossom end rot and is caused by a calcium deficiency, usually induced by any disruption of water uptake.
Lack of water, even short-term, especially after heavy rainfall, will result in reduced calcium intake. High humidity, which causes a reduction in evapotranspiration and water uptake in plants, will have the same effect.

Fruit stored in a cold chamber exhibit a longer storage life because the rate of respiration is decreased.
Fruits when stored in a cold chamber exhibit a longer storage life because their rate of respiration is decreased. When fruit respires they release out ethylene which helps in ripening. Ethylene is also known as the 'fruit-ripening hormone'. Every fruit has a different level of ethylene production.

The Ridge of greenhouses should be oriented in the North-south direction to avoid sun scorching.
The greenhouse should be situated lengthwise from north to south rather than east to west. This position provides the structure with more light and less shade. While unobstructed sunlight is important, afternoon shade may be as important depending upon the types of plants grown and the time of year they are grown.
For low-light crops and special applications such as rooting cuttings, shade is used as a necessary means of limiting total solar radiation.
