Are yellow tomatoes higher in carotene?
The general answer is no with some exceptions. Carotene normally expresses an orange color so yellow tomatoes will be low in carotene. Caro Rich is a high carotene tomato that has good production of bright orange tomatoes. Its taste is acceptable but not as good as some of the better yellow/orange tomatoes such as Lillians Yellow Heirloom, Kelloggs Breakfast, Dr. Wyche, etc. Why do diced tomatoes contain calcium chloride? It increases turgor pressure and helps the pieces to remain whole during processing. Touch me, I like it. What is thigmatropy? Thigmatropy is the name for an effect where plants alter their growth habits as a result of being touched. It was first noticed in greenhouses where plants next to the aisles were found to grow sturdier and healthier. The cause was workers walking down the aisle brushing against the plants. You can stimulate thigmatropy by rubbing your hands or a stick across the tops of the plants a couple of times a day or by placing a fan so it blows gently
