Survival and growth of Juniperus seedlings in Juniperus woodlands

Plant Ecology, 2005
Juniperus woodlands are widely distributed in western North America. Few studies of seedling emergence, long-term survival, growth or mortality of the dominant Juniperus spp. in these woodlands have been carried out. Consequently, regeneration dynamics in these woodlands are poorly understood. Juniperus ashei is the dominant woody plant in the majority

Predicting first year seedling survival from quality distributions of bareroot seedlings and microsites

, 2022
Seeding survival has been a continuing problem since the start of the commercial pine plantation in 1950s. The first-year survival of bare-root loblolly pine seedlings at intensively prepared sites in Louisiana has reached a survival plateau of 75 to 85 %

NEIGHBORHOOD AND COMMUNITY INTERACTIONS DETERMINE THE SPATIAL PATTERN OF TROPICAL TREE SEEDLING SURVIVAL [PDF]

Ecology, 2007
Factors affecting survival and recruitment of 3531 individually mapped seedlings of Myristicaceae were examined over three years in a highly diverse neotropical rain forest, at spatial scales of 1–9 m and 25 ha.

Germination, the Survival of Seedlings and Competition

1993
Went (1953) has summarized his research carried out in the Mojave and Colorado deserts of North America (in collaboration with M. Juhren and E. Phillips) (Went 1948, 1949; Went and Westergaard 1949). He arrived at the conclusion that evolution plays only a minor role in the selection of desert annuals after they have germinated.

Embryo and Seedling Survival and Plant Development

2002
Osborne and Boubriak (1994) defined five stages during seed development, maturation, the post-maturation period and dehydration. These are two stages of intolerance to desiccation and three stages of desiccation tolerance. When the seed moisture content is reduced to below 10%, seeds become drought-tolerant, as also do seeds that are rehydrated to ...

The effects of neighbors on the growth and survival of shrub seedlings following fire

Oecologia, 1995
Where plant species vie for limited resources, disturbances might preclude competition by releasing a flush of nutrients, or by reducing biomass and thereby diminishing the consumption of resources. However, if new seedlings colonize in clumps, they may still deplete resources within the local aggregations, which may then reduce their growth and ...

Survival of shoot meristems of tomato seedlings frozen in liquid nitrogen

Cryobiology, 1978
Abstract An explant containing the primary shoot meristem was dissected from intact tomato seedlings after thawing from liquid nitrogen. Surviving explants produced shoots directly by normal meristem growth when cultured in the presence of gibberellic acid.

Survival and Growth of Chestnut Backcross Seeds and Seedlings on Surface Mines

Journal of Environmental Quality, 2013
Some scientists consider the loss of the American chestnut from forests in the eastern United States as one of the greatest forest ecological disasters in the 20th century. The American Chestnut Foundation has been attempting to restore chestnut by backcrossing blight-resistant Chinese chestnut to American chestnut and selecting those strains with ...

Evolutionary history and distance dependence control survival of dipterocarp seedlings

Ecology Letters, 2009
AbstractOne important hypothesis to explain tree‐species coexistence in tropical forests suggests that increased attack by natural enemies near conspecific trees gives locally rare species a competitive advantage. Host ranges of natural enemies generally encompass several closely related plant taxa suggesting that seedlings should also do poorly around

Factors affecting survival of tree seedlings in North Queensland rainforests

Oecologia, 1992
Seedlings of six species of rainforest trees with widely constrasting ecology and seed morphology were transplanted at 3 weeks of age into tree-fall gaps and the shaded understoreys at two rainforest sites (Curtain Fig and Lamins Hill) on the Atherton Tableland, North Queensland, Australia.
