Nurse plants also aid with recovery after herbivore grazing, because they provide higher levels of resources to the plant. [8] The effect of nurse plants on any particular species is dependent upon species richness and the dispersal strategy of the organism. [8] Nurse plants can help with seedling recruitment and protect plants from granivory.
Oats as nurse crop for alfalfa. In agriculture, a nurse crop is an annual crop used to assist in establishment of a perennial crop. [1] The widest use of nurse crops is in the establishment of legumaceous plants such as alfalfa, clover, and trefoil. [1] [2] Occasionally, nurse crops are used for establishment of perennial grasses. [citation needed]
For example, seed germination and survival in harsh environments is often higher under so-called nurse plants than on open ground. [1] [3] A nurse plant is one with an established canopy, beneath which germination and survival are more likely due to increased shade, soil moisture, and nutrients. Thus, the relationship between seedlings and ...
Nurse grafting is a method of plant propagation that is used for hard-to-root plant material. If a desirable selection cannot be grown from seed (because a seed-grown plant will be genetically different from the parent), it must be propagated asexually ( cloned ) in order to be genetically identical to the parent.
The greater efficiency of water use in newly transplanted 3-year-old white spruce seedlings under low levels of absolute humidity difference in water-stressed plants immediately after planting [70] helps explain the commonly observed favourable response of young outplants to the nursing effect of a partial canopy. Silvicultural treatments ...
A nurse tree in an Oregon forest Young saguaros under a nurse tree. A nurse tree is a larger, faster-growing tree that shelters a smaller, slower-growing tree or plant. The nurse tree can provide shade, shelter from wind, and protection from animals that would feed on the smaller plant and significant changes in temperature. [1]
In agriculture, cover crops are plants that are planted to cover the soil rather than for the purpose of being harvested.Cover crops manage soil erosion, soil fertility, soil quality, water, weeds, pests, diseases, biodiversity and wildlife in an agroecosystem—an ecological system managed and shaped by humans.
A nurse log is a fallen tree which, as it decays, provides ecological facilitation to seedlings. Broader definitions include providing shade or support to other plants. Some of the advantages a nurse log offers to a seedling are: water, moss thickness, leaf litter, mycorrhizae, disease protection, nutrients, and sunlight.
