    en.wikipedia.org/wiki/Pyrenochaeta_lycopersici

    [3] [6] These microsclerotia can survive under harsh environments such as temperature changes and drought, and they can maintain the ability to infect other hosts in the soil for up to 15 years. [7] Once the environment becomes favorable for the pathogen growth, germination will occur in microsclerotia that leads to the production of hyphae. [6]

  3. Physical properties of soil - Wikipedia

    en.wikipedia.org/wiki/Physical_properties_of_soil

    Soil temperature depends on the ratio of the energy absorbed to that lost. [68] Soil has a mean annual temperature from -10 to 26 °C according to biomes. [69] Soil temperature regulates seed germination, [70] breaking of seed dormancy, [71] [72] plant and root growth [73] and the availability of nutrients. [74]

  4. Tomato leaf mold - Wikipedia

    en.wikipedia.org/wiki/Tomato_leaf_mold

    Spores germinate in the leaf surface with free water and humidity with above 85%. [8] This pathogen can survive at least one year without a host which is called non-obligate. The temperature must be between 40°~94 °F (4°~34 °C) for germinating spore. The pathogen usually infects the leaves by penetrating through stomata in a high humidity ...

  5. Germination - Wikipedia

    en.wikipedia.org/wiki/Germination

    Note: Temperature must be kept at an optimum level. Disturbance of soil can result in vigorous plant growth by exposing seeds already in the soil to changes in environmental factors where germination may have previously been inhibited by depth of the seeds or soil that was too compact. This is often observed at gravesites after a burial. [1]

    Test your soil’s pH, aiming for a range of 6.0 to 6.8, which is optimal for tomato growth. Regularly replenish nutrients with natural fertilizers during the growing season to support fruit ...

  7. Stratification (seeds) - Wikipedia

    en.wikipedia.org/wiki/Stratification_(seeds)

    Warm stratification requires temperatures of 15–20 °C (59–68 °F). In many instances, warm stratification followed by cold stratification requirements can also be met by planting the seeds in summer in a mulched bed for expected germination the following spring. Some seeds may not germinate until the second spring. [citation needed]

    Most wildflower seeds need light to germinate and they won’t grow if they’re buried in soil. Add straw and water. Apply a light layer of weed-free straw over the area after planting and then ...

  9. Growing degree-day - Wikipedia

    en.wikipedia.org/wiki/Growing_degree-day

    Growing degrees (GDs) is defined as the number of temperature degrees above a certain threshold base temperature, which varies among crop species. The base temperature is that temperature below which plant growth is zero. GDs are calculated each day as maximum temperature plus the minimum temperature divided by 2, minus the base temperature.
