Clonal production of loblolly pine (Pinus taeda L.) through somatic embryogenesis has great potential to meet the increasing industrial demands for highquality uniform raw materials. A major barrier to the commercialization of this technology is the low quality of resulting embryos. Twenty-five newly initiated loblolly pine genotypes were followed through the process of liquid culture establish...

With regard to desired natural regeneration establishment that it is the goal of selection systems. The role of tree and group selection silvicultural systems on the quantity and quality of natural regeneration was conducted at four site of forest. First, 100 circular sample plots has been selected by use of random systematic inventory. Then into the each plots nine micro-plots defined. The res...

The demand for bigger, better, faster-growing seedlings has been ever-growing. As a result, forest seedling production is a continually evolving technology in reforestation. Evaluating seedling quality is crucial for understanding seedling development in the nursery, as well as subsequent field growth and survival. Stock quality, however, often is assessed inconsistently and on only a limited b...

The liming and mineral fertilization can improve the growth quality of forest species seedlings. effects application nitrogen fertilizer rates limestone on Peltophorum dubium (Sprengel) Taubert seedlings were investigated in this study. plants grown 1.4-L polyethylene bags filled with sandy soil under greenhouse conditions. Treatments arranged a randomized block design 4 × 2 factorial: four N (...

Somatic embryogenesis (SE) cloning techniques for Nordmann fir Christmas tree production have been pursued and refined in Denmark, three SE clonal trials with 201 clones from seeds of 27 trees seedlings bulk harvest Georgia, Caucasus, were established 2014 to 2015. This study was the first evaluate genetic performance these different sites. In addition, (zygotic) normal field compared this stud...

Background: The conventional fertilization regime ignores the allometric characteristics of Quercus nuttallii seedlings, challenging them to meet nutritional needs at each growth stage. This study was conducted determine impact exponential on and nutrient status Q. container seedlings. Methods: Two regimes (average/exponential) were performed varied gradients (0, 300, 500, 700, 900 mg/seedling)...

ABSTRACT Physiological and nutritional management is an important practice for obtaining high quality seedlings. The use of seaweed extract has emerged as alternative to fertilizers biostimulants, although information on this with respect Alibertia edulis, a fruit-bearing species native the Cerrado region, scarce. aim study was evaluate effects Ascophyllum nodosum L. (ANE), both without additio...

Low temperature is one of the major factors limiting pepper (Capsicum annuum L.) production during winter and early spring in non-tropical regions. Application of exogenous abscisic acid (ABA) effectively alleviates the symptoms of chilling injury, such as wilting and formation of necrotic lesions on pepper leaves; however, the underlying molecular mechanism is not understood. The aim of this s...
