Abstract:
Ectomycorrhizae formation, seedling health index, and seedling survival were assessed for two-year-old nursery-grown seedlings of Pinus resinosa and Pinus strobus two months after planting in clear-cuts that had received prescribed burning under different fire intensities. Controls consisted of seedlings planted in unburned clear-cuts. Fire intensity positively correlated with percent ectomycorrhizal roots for P. strobus but not for P. resinosa. Seedling health index and survival were highest in burned-over sites as compared to control sites for both pine species. Fire intensity correlated wit

Regressions did differ between seedling lots and between seedlings that had roots only, shoots only, or both roots and shoots exposed. Since the differences between root and shoot ψ were sometimes la

Phosphorus deficiency differentiated total phosphatase activity in seedling cotyledons and increased the activity in the excised cotyledons.

Abstract:Seeds of Eugenia species can produce new roots and whole plants even when much of its reserves is removed. However, new roots and seedlings rarely are formed spontaneously, and after cutting, each seed fragment usually produces only one new seedling, suggesting some control of the formation of several seedlings. It is possible, therefore, that germination leads to the production of inhibitory substances avoiding the development of new embryonic tissues. In the present work we have analyzed the potential of germinating seeds of Eugenia uniflora and Eugenia brasiliensisto inhibit new ro

Abstract Fractal geometry is a simple method of quantifying and describing complex shapes often found in nature (Mandelbrot 1983). The spatial arrangement of pine seedling roots is complex and not easily quantified. In this paper we report on a method for quantifying seedling roots based on concepts of fractal geometry. Ten 1+0 bareroot seedlings of each of three grades of loblolly pine (Pinus taeda L.) were obtained from two Virginia Department of Forestry nurseries. The fractal dimension (D) was estimated for seedling roots using a computer-based box-count method. The results show that pine

This dissertation addressed the following ecological and ethnoecological questions. Can seedling traits help us understand why so few woody species have encroached markedly into North American desert grasslands, and the conditions likely to promote their proliferation? What is the role of informal knowledge of the environment in efforts to manage woody plant abundance? Woody seedling survival often depends on rapid taproot elongation. In glas

Root growth potential (RGP), the ability of a transplanted seedling to rapidly elongate existing roots and initiate new roots, is used as an indicator of seedling physiological quality.

In the first study, seedlings were hand-lifted from September to April at 17-day intervals in 1983-84 and 7-day intervals in 1984-85. The RGP variation over time was related to environmental and seedling phenological changes. In addition, the new root systems were morphologically describe

Abstract:
One of the most important ways to reduce Atmospheric carbon is the carbon sequestration by trees. In this study, by using some morphological characteristics of the root and stem of Oak seedling the carbon sequestration evaluated. For this purpose, one hundred seedlings were sampled by method of Systematic-Random from the planting bed on March 2022 in the Pylambra nursery at Guilan province. Seedlings are divided to three grades small, medium and large according to Root Collar Diameter (RCD). The biomass and carbon sequestration of Oak seedling calculated according to the basic density of its r

Abstract:
Creating forest curtains on sandy or highly compacted lands affected by desertification necessitates precise control, given the challenges associated with the soil management in these regions. The mechanisms designed for planting forest seedlings face significant challenges: the working apparatus responsible for handling seedlings during planting can inflict notable damage to the stems, particularly through scratching or crushing. This issue usually arises from the design solution and the shape of the mechanical organ handling the seedlings. Moreover, it is highly important to improve the cont

This study aimed to examine the effect of different media - Murashige Skoog (MS) and Gamborg (B5) on the growth and development of in vitro seedling cultures of wheat (Triticum aestivum L.). The effects were evaluated through the measurement of root and shoot length, fresh and dry mass, as well as through the determination of the concentration of photosynthetic pigments (chlorophyll a, chlorophyll b, and carotenoids). The obtained data indicate that MS has better effects on the growth and development of wheat seedlings, since longer shoot length, and better fresh weight were observed on seedli

Compared to the Reglalg variants, root growth of control seedlings was more strongly affected by HS, since the activity levels of CAT, PO and MDA content in the roots were higher. This demonstrates

For example, we saw parts of the moorva dregea (Wattakaka volubilis), belonging to the family Apocyanaceae, and jengkol (Archidendron pauciflorum), belonging to the family Fabaceae, being consumed as vegetables. These plants are generally considered poisonous by scientists. Likewise, the roots of the winged bean (Psophocarpus tetragonolobus) and the seedlings of the wine palm (Bor

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:
Root-knot nematodes (RKN), Meloidogyne spp., are extremely destructive pathogens of cucurbit crops grown in the United States and Israel. The safety and environmental concerns of toxic nematicides, and limited sources of natural cucurbit resistance to the four major species of Meloidogyne that threaten these crops in Israel and the U.S., have emphasized the use of biotechnology to develop cucurbits with novel RKN resistance. The U.S. scientists have identified over 40 unique RKN parasitism genes that encode nematode secretions involved in successful plant root infection by RKN, and they have d
