Even if GE trees are bred to be sterile--as many varieties being developed are the report notes that reproduction can still happen since trees can also reproduce vegetatively
through roots, or from broken branches, or shoots inadvertendy transported by wind, water, animals, and humans.
The most abundant species in our study had some trait similarities: they disperse mainly by wind, to a lesser extent vegetatively
, and have similar demands to some environmental conditions, such as openness to light, (moderately) acidic soil, but are rather indifferent to the moisture content or prefer moderate to wet habitats (Ellenberg et al.
lumbricalis, the loose-lying form of the species is sterile and reproduces only vegetatively
, mainly by fragmentation (Austin, 1960; Norton and Mathieson, 1983; Bird et al.
The lack of plantation material is one of the factors that limits the expansion of tannia cultivation in several vegetatively
They flower only rarely and increase vegetatively
I also suggested that for germline cells and for the cells of vegetatively
propagated organisms and immortal cell populations like most cancer cell lines, an enzyme might be activated that would prevent the diminution of DNA termini at each cell division, thus protecting the information containing part of the genome.
The bermudagrass cultivar Tifgreen, released in 1956, launched the era of high-quality, vegetatively
propagated turfgrasses, but has also led to problems with the appearance of off-types on putting greens.
He said that unlike the most popular current miscanthus that is vegetatively
propagated, Ceres' seeded types are expected to require significantly less time, effort and money to be bred for different environments and to be established by growers.
Ice scouring, infertile sandy soils, flooding by beavers, and open shorelines are among the stresses that shift communities to be less vegetatively
productive, albeit possibly more diverse, assemblages (Mitsch & Gosselink 2007).
propagated varieties from Ball FloraPlant have won critical acclaim for their ability to produce clean, healthy cuttings.
This species dominates the nopal ecosystem through its long life span and ability to reproduce vegetatively
by rooting of cladodes (Mandujano et al.
Subsequent chapters turn to the central focus of the book, including reproductive biology, breeding techniques, mutations and cultivar development, biotechnology in Musa improvement, genotype by environment interaction and Musa improvement, quality improvement of cultivated Musa, postharvest processed products from the banana, propagation methods, adoption and challenges in hybrid distribution to farmers, and lessons learned from the molecular breeding of other vegetatively
