Tomato seeds have a long shelf life. They can last up to a decade or even longer if stored in a cool, airtight spot. Under less than ideal conditions, you can expect closer to five years.
All other tomatoes should be kept at least 20 feet (6.1 m) apart to reduce the possibility of cross-pollination. Seed should be saved from tomatoes picked from several different plants throughout the growing season that are true to type to preserve genetic diversity. These seeds should be mixed at the end of the growing season. [4]
The Early Girl tomato is a medium-sized globe-type F1 hybrid popular with home gardeners because of its early ripening fruit. Early Girl is a cultivar of tomato with indeterminate growth, which means it produces flowers and fruit until it is killed by frost or another external factor (contrast with a determinate cultivar, which would grow to a limited, predefined shape and be most productive ...
Seed dormancy is especially adaptive in fire-prone ecosystems. [4] [5] Some seeds have a very long viability period, and the oldest documented germinating seed was nearly 2000 years old based on radiocarbon dating. [6]
All tomato plants, especially indeterminate varieties, will do better if either caged or staked. Indeterminate varieties can grow from 6 to 8 feet tall and even determinate varieties can grow 3 to ...
Vernalization (from Latin vernus ' of the spring ') is the induction of a plant's flowering process by exposure to the prolonged cold of winter, or by an artificial equivalent. After vernalization, plants have acquired the ability to flower, but they may require additional seasonal cues or weeks of growth before they will actually do so.
The plants require proper spacing (2 feet) between each plant to ensure that diseases do not spread. [5] Staking is a necessary method that is required by the tomato plants since it can grow up to 10 feet tall and the fruits can become quite heavy and large in size. [11]
A genetically modified tomato, or transgenic tomato, is a tomato that has had its genes modified, using genetic engineering. The first trial genetically modified food was a tomato engineered to have a longer shelf life (the Flavr Savr ), which was on the market briefly beginning on May 21, 1994. [ 1 ]
