Abstract:

In midsuccessional old fields, seedlings are often concentrated in patches of disturbed ground, such as earth mounds created by burrowing mammals. An experiment was conducted to determine whether interspecific variation in seedling density on mounds reflected interspecific variation in potential seedling establishment (i.e., the number of seedlings established per 1000 seeds sown). Seeds of 13 old-field forbs were sown on experimentally created mounds in an abandoned pasture. Their potential seedling establishment ranged from 0 to 156 seedlings per 1000 seeds sown, and seedling establishment w

We investigated the effects of overstory canopy openness and seedling density on seedling morphology and growth in the mid-successional species Acer nipponicum Hara in a cool-temperate forest. Studied seedlings were 46 seedlings of 30–160 cm height, and their overstory canopy openness ranged between 7.2% and 17.0%. Seedling density, measured as the number of conspecific neighboring seedlings within a 50 cm radius of the target seedling, ranged between 0 and 19. There were no significant correlations between seedling height, canopy openness, and seedling density. Multiple regression analysis sh

Purple rice has become a fascinating source of nutritional value among healthy cereal grains. A field experiment was conducted at Bangladesh Agricultural University during the Rabi season (February to May) of 2021 to evaluate the effect of number of seedlings/hill on growth, yield attributes and yield of Purple rice. Three seedling densities, viz. 1, 2 and 3 seedlings/hill, and three rice cultivars, viz.

Greater age of the seedlings and their inherent development generally served to improve photo interpretation. The amount of woody competition present in the plots tended to h

Individual differences in fecundity often serve as proxies for differences in overall fitness, especially when it is difficult to track the fate of an individual's offspring to reproductive maturity.

To test for such density-dependent effects in plants, we sowed seeds of the wildflower Ipomopsis aggregata (scarlet gilia) to mimic partially overlapping seed shadows of pairs of plants, one of which produced twic

Consequently, there are compelling reasons to deepen our understanding of the mechanisms that maintain these highly diverse forests and of the potential long-term threats to their preservation. An important process shaping tropical plant communities is negative density dependence (NDD). NDD occurs when plant performance is negatively impacted by increased neighbourhood density.

The seed bank is directly related to forest resilience because it contributes to the greatest number of regenerants after the occurrence of disturbances.

For example, suppression of the seed bank can occur in pastures, that experience frequent fires with increase of density of seeds and predominance of herbs are typical of highly degraded areas, such as Poaceae, Rubiaceae, Asteraceae, and Cyperaceae.

Abstract The classical approach to measuring plant growth rate likened it to compound growth rates of bank accounts, where the rate of increase in plant biomass is proportional to the amount of biomass already present in the plant, implying that plant growth is exponential. It was determined that variation in relative growth rate (RGR) among herbaceous plants was driven by the leaf area ratio (LAR)—and more specifically—specific leaf area (SLA). The classic growth equations are confounded by plant size. While exponential growth may be true for the early stages of growth in herbaceous plants, p

Лесовосстановление посадочным материалом с закрытой корневой системой имеет ряд преимуществ по сравнению с традиционными технологиями. Однако данная технология требует решения некоторых задач с целью оптимизации процессов выращивания сеянцев. Одним из проблемных моментов является выбор оптимальных по своим как агрохимичес

Abstract:

Resource managers at Pea Ridge National Military Park manage the natural communities of the park as a backdrop for interpreting the civil war battle that occurred on March 7–8, 1862. Restoration of the landscape to the vegetation communities that were present at the time of the battle is ongoing. Priorities for restoration include density, form, and vegetation structure, but native representative species are also desired. Heartland Inventory and Monitoring Network ecologists observed plant community sites in park woodlands in 2007, 2012, 2016, and 2021. Climate may influence vegetation and oth

NGPN did not visit SCBL in 2020 or 2021 due to travel restrictions during the COVID-19 pandemic. However, NGPFire was able to do vegetation monitoring at SCBL during these two years.

Abstract:

Background Transplanting vegetable seedlings to final spacing in the greenhouse is common practice. At the time of transplanting, the transpiring leaf area is a small fraction of the ground area and its cooling effect is rather limited. A preliminary modeling study suggested that if water supply from root to canopy is not limiting, a sparse crop could maintain about the same canopy temperature as a mature crop, at the expense of a considerably higher transpiration flux per leaf (and root) area. The objectives of this project were (1) to test the predictions of the model, (2) to select suitable

Abstract:

The objectives that were outlined in our original proposal have largely been achieved or will be so by the end of the project in February 1995 with one exception; that of mapping cold tolerance loci based on the segregation of tolerance in the BC1 progeny population. Briefly, our goals were to 1) construct a densely populated linkage map of the citrus genome: 2) map loci important in cold and/or salt stress tolerance; and 3) characterize the expression of genes responsive to cold land salt stress. As can be seen by the preceding listing of accomplishments, our original objectives A and B have
