We have about 60 tomato plants in our allotments that have been doing so wonderfully.  Many of them have tomatoes forming on them.  The thermometer this morning indicates that we may have been to early and will pay for it.  I hope the repercussions are limited.  As I understand it, anything around or below 50F can be bad news for tomatoes.

According to NCSU, hopefully the worst we will see is blossom and/or fruit drop.  Other sources tell of stunted plant growth.  I like NCSU’s take on it instead so I’ll stick with that one.

Although we think of tomatoes as an adaptable crop, they are actually quite sensitive to low light and adverse temperatures. Tomatoes need at least 6 hours of direct sunlight to flower. Slender, non-fruiting tomato vines are a common complaint of home gardeners and are usually traceable to shading. Many homeowner and grower complaints can also be attributed to high or low temperatures. Although tomatoes grow well over a wide range of temperatures (65 to 85 degrees F), fruit set is very sensitive to high and low temperatures. Above 90 degrees F day or 70 degrees F night temperatures and below 50 to 55 degrees F, flowers may produce oddly-shaped (rough) fruit or flowers may fall off without setting fruit at all. Malformed fruit are sometimes said to be ‘catfaced’ or to have open locules. These malformations are the result of incomplete separation of cells during the early stages of flower and fruit development. Adverse effects seem to be worst when both day and night temperatures are high or when both are low. Proper coloring of the fruit is also temperature dependent. Lycopene and carotenes are not synthesized above 85 degrees F and lycopene is not synthesized below 50 degrees F, precluding normal color development in ripening fruit.
