Schima superba is an important dominant species in subtropical evergreen broadleaved forests of China, and plays a vital role in community structure and dynamics. However, the survival rate of its seedlings in the field is low, and water shortage could be a factor that limits its regeneration. In order to better understand the response of its seedlings to drought stress on a functional genomics...

-This study analyzed spatial location patterns of Cercocarplls ledifolills :'\Jutt. (curlleaf mountain mahogany) plants, classified as current-year seedling, established seedling, juvenile, and immature individuals, at a central :'\evada study site. ~Iost current-year seedlings were located in mahogany stands in which large, mature individuals had the greatest abundance. These stands had greate...

The sweetpotato whitefly, Bemisia tabaci MEAM1 Gennadius (Hemiptera: Aleyrodidae), and the complex of viruses it transmits are major limiting factors to squash production in southeastern United States. At this time, insecticides extensively relied upon for management whiteflies and, indirectly, whitefly-transmitted viruses. development a multi-faceted, integrated pest (IPM) program is needed in...

Elliott, K.J. and White, AS., 1993. Effects of competition from young northern hardwoods on red pine seedling growth, nutrient use efficiency, and leaf morphology. For. Ecol. Manage., 57. 233255. The effects of competition from three northern hardwood tree species on red pine (Pinus resinosa Ait. ) seedlings were examined on two clear-cut sites in western Maine. We examined how planted red pine...

Seedlings are an important stage for plant populations, as the abundance and rigor of seedlings can indicate a changing forest structure in future. Studying different traits seedling represent how grows. Biomass is one that plant’s performance many other growth processes seedling. Several allometric equations have been developed to estimate tree biomass. However, biomass remains poorly studied,...

As a result of extensive deforestation, the survival of many tropical forest species may depend on disturbed forests. However, recent studies demonstrate that tree regeneration following logging can be slow, decreasing the conservation value of disturbed forests. Here we test whether the dominating herb, Acanthus pubescens, in the understory of logged forest, suppresses tree regeneration in Kib...

Natural regeneration is the interaction of natural processes to restore forest ecosystem. Its dynamics are influenced by intensity and extent a series abiotic biotic factors, which may be intrinsic or extrinsic. Knowing importance establishing within ecosystems, this work aimed evaluate whether litter depth trail distance seedling abundance richness in fragment undergoing restoration. The hypot...

Abstract Bryophytes, which include mosses, liverworts and hornworts, indeed play a significant role in the natural dynamics of native forests. They contribute to fundamental ecological processes such as tree regeneration. In this context, objective was analyse association bryophytes with Nothofagus seedlings, well whether substrates where grew influenced bryophyte‐tree seedling association, sub...

Paper birch (Betula papyrifera Marsh) seedlings were grown in a greenhouse in either subsoil or topsoil in factorial combination with two fertilization and drought regimes to investigate how different soil environments and nutrient availability drive belowground partitioning between growth, secondary metabolism and ectomycorrhizal (EM) associations, and impact drought tolerance of paper birch. ...

The present study is focused on the importance of SNP, a NO donor, as Cd stress modulator on seedlings of cabbage. The exogenously applied Cd induced stress in cabbage seedlings to explore the protective role of SNP. 21-day-old seedlings were grown in Hoagland solution and Cd at 0.5 and 0.7 mM concentration with and without SNP. The biophysical and biochemical parameters were analyzed. Cd exhib...
