Abstract Fertilization in the seedling production phase is essential to form quality seedlings. Thus, aim of this study was evaluate appropriate doses two slow-release fertilizers (SRF1 and SRF2) their nutrient leaching behavior. For this, five different were tested. 0, 2, 4, 6, 8 kg m-³. The height, stem diameter, leaf area, shoot dry mass, root system total Dickson Quality Index measured, for...
Acer rubrum L., A. saccharum Marsh., Quercus alba L. and Q. rubra L. seedlings subjected to soil and stem base heat treatments showed rapid declines in rates of transpiration and photosynthesis. Reductions in photosynthetic rate were partly attributable to mesophyll inhibition. Quercus seedlings were less able to maintain transpiration and photosynthesis after heat treatment than Acer seedlings...
these days, all department stores make an effort to provide their clients with valuable products in order to project the best image for them. as a result, clients’ comprehension risk will decrease and they will be more willing to repurchase. having a good image is really important for the department stores because it makes an impression on clients’ comprehension of both quality and risk. consid...
Grafting on epicotyl of young seedlings has been introduced as a simple and rapid method for walnut propagation. Although this technique improves the grafting success and propagation efficiency, it is technically more demanding than the conventional walnut grafting procedures and is yet to be optimized. This study was aimed to investigate the influence of rootstock type (dwarf and standard geno...
Longleaf pine is a highly desirable species, resisting fire, insects and pathogens, and produces quality solid-wood products, but regeneration of the species has been difficult. Natural regeneration is feasible only on a small portion of the area considered to be longleaf pine type. Therefore, artificial regeneration must become a reliable means of regenerating the species if restoration of the...
In this study, we aimed to evaluate growth and quality of Berberis laurina seedlings submitted increasing doses controlled-release fertilizer (CRF). Each treatment was elaborated with different CRF Basacote® Plus 9M: 0.0, 2.5, 5.0, 7.5, 10.0, 12.5 kg m-3. Seedlings were measured at 15, 30, 60, 90, 150 days in height stem diameter. At days, evaluated aerial dry biomass, root height/ diameter rat...
Vegetable plug seedling has become the most important way to produce vegetable seedlings in China. This seedling method can significantly improve the quality and yield of vegetables compared to conventional methods. In the process of plug seedling, chemical fertilizers or pesticides are often used to improve the yield of the seedlings albeit with increasing concerns. Meanwhile, little is known ...
in this research corn were planted in 3 densities (8, 12, 16 plant/m2) in two planting patterns (single and double-row) with seven summer weed species, including redroot pigweed, green foxtail, annual bluegrass, common lambsquarter, jimsonweed, black nightshade and johnsongrass were planted. temperature, quality and quantity of light reaching to soil surface were measured and the number of emer...
Seedling regeneration after a high intensity wildfire was assessed in a mixed forest dominated by Eucalyptus species andCallitris endlicheri (Parl.) F.M.Bailey. Patternswere compared against the ‘slow seedling’or ‘tortoise-and-hare’ theory of competitive interactions betweengymnosperms andangiosperms.Browsing effectswere documentedusing fenced plots, and seedling density, mortality and height w...
The effects of pre-hardening fertilization and autumn on seedling growth have been studied separately, but studies their combined are relatively scarce. We the type level biomass allocation root morphology container-grown seedlings Korean pine (Pinus koraiensis Sieb. et Zucc.), a valuable evergreen conifer distributed from Changbai Mountain to Xiaoxing’an Mountains in northeastern China. Three ...
