After germination, transport plants to an area with a temperature of 60–70 °F (16–21 °C). Keep under light for at least 12 hours a day. Plant seeds 6 inches (15 centimetres) apart to prevent crowding. Remove deceased plants to promote growth for newly planted ones.
Seedlings have at least 2 sets of true leaves and a strong root system that can’t be easily lifted from the potting medium if you gently pull up on the plant’s stem. Seedlings are rootbound or ...
The fungi can also benefit the growth of the seedlings as it can enhance seedling growth rate, tiller number and height, and overall biomass. [64] Because seeds are an important aspect of both fecundity and competitive ability for plants, high germination rates and seedling survival increase lifetime fitness. [5]
Plant defense against herbivory or host-plant resistance is a range of adaptations evolved by plants which improve their survival and reproduction by reducing the impact of herbivores. Many plants produce secondary metabolites , known as allelochemicals , that influence the behavior, growth, or survival of herbivores.
A foxtail is a spikelet or cluster of a grass, that serves to disperse its seeds as a unit. Thus, the foxtail is a type of diaspore or plant dispersal unit. Some grasses that produce a foxtail are themselves called "foxtail", also "spear grass". They can become a health hazard for dogs, cats, and other domestic animals, [1] and a nuisance for ...
In small plants and seedlings, Verticillium can quickly kill the plant while in larger, more developed plants the severity can vary. Some times only one side of the plant will appear infected because once in the vascular tissues, the disease migrates mostly upward and not as much radially in the stem. [ 3 ]
They were discovered in the 1940s after a long study of the plant growth regulator auxin. Synthetic auxins mimic this plant hormone in some way. They have several points of action on the cell membrane, and are effective in the control of dicot plants. 2,4-D, 2,4,5-T, and Aminopyralid are examples of synthetic auxin herbicides.
High densities of seeds occur in the upper soil of Ceanothus communities. Seeds remain viable up to 24 years or more. Seed dormancy is broken by the removal of the seed coat by fire scarification or physical disturbance. [5] [7] Seeds germinate best at about 1 inch soil depth in shady areas in the spring following fire scarification. [5] [7]
