Edited and revised by David C. Plant propagation is the process of creating new plants. There are two types of propagation:

Mix seed with the sphagnum or peat and place in a plastic bag. If they are covered at all, cover them lightly with fine peat moss or fine vermiculite. When roots begin to show, place the seeds in containers or plant them directly in the garden. Very little success in grafting will be obtained unless proper care is maintained for the following year or two.
There is a wide variety of containers from which to choose for transplanting seedlings. In this sample, 19 of the 24 strains were female-fertile and all population genetics indices genotypic diversity, linkage disequilibrium were consistent with contemporary sexual reproduction [ 31 ]. Multi-cell containers packs where each cell holds a single plant reduce the risk of root injury when transplanting young plants.
Impress strategies include mechanisms and responses plants use to reproduce, defend, survive, and compete on the vista. Strategies have been classified as adaptive strategies entirely a change in the genotype ,   reproductive strategies,  resource allocation strategies,    ecological strategies,  and functional trait based strategies,   to name a few.
While numerous strategies exist, a person underlying theme is constant: These trade-offs and responses lay the groundwork as a service to classifying the strategies that emerge. The concept of plant strategies started gaining attention in the s and s. According to Grime , plants expand strategies that demonstrate resource trade-offs between growth, print, and maintenance. This started a movement towards incorporating functional traits in fix strategies, and understanding how plant functional traits and environmental factors are tied up.
Grime identified two proxy gradients, broadly categorized as disturbance and stress Literate, which limit plant biomass. Stresses include factors such as the availability of water, nutrients, and luminous, along with growth-inhibiting influences like temperature and toxins.

Sexual reproduction is common in eukaryotic microorganisms, with few species reproducing exclusively asexually. However, in some organisms, such as fungi, asexual reproduction alternates with episodic sexual reproduction events.
Fungi are thus appropriate organisms for studies of the reasons for the selection of sexuality or clonality and of the mechanisms underlying this selection. Magnaporthe oryzae , an Ascomycete causing blast disease on rice, reproduces mostly asexually in natura. Sexual reproduction is possible in vitro and requires i two strains of opposite mating types including ii at least one female-fertile strain i.
Female-fertile strains are found only in limited areas of Asia, in which evidence for contemporary recombination has recently been obtained. We induced the forced evolution of four Chinese female-fertile strains in vitro by the weekly transfer of asexual spores conidia between Petri dishes. We aimed to determine whether female fertility was rapidly lost in the absence of sexual reproduction and whether this loss was controlled genetically or epigenetically. All the strains became female-sterile after 10 to 19 rounds of selection under asexual conditions.
As no single-spore isolation was carried out, the observed decrease in the production of perithecia reflected the emergence and the invasion of female-sterile mutants.
The female-sterile phenotype segregated in the offspring of crosses between female-sterile evolved strains and female-fertile wild-type strains. This segregation was maintained in the second generation in backcrosses.
