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

The objective of this work was to evaluate the dependence of cucumber (Cucumis sativus L.) seedlings on cotyledonary leaves for early growth and establishment. Sets of two uniform emerging seedlings were used to quantify the initial growth and dry matter accumulation, as well as the intensity and stage of cotyledon damage in seedling establishment and to determine cotyledon protein, amino acid and carbohydrate contributions to the growing seedling. Cucumber seedling establishment was found to be highly dependent on cotyledonary leaves. Root system establishment was highly dependent on the heal

Abstract Jeffrey pine (Pinus jeffreyi) seeds have large wings and are effectively dispersed by wind, but 37% of the seedling emergence sites in spring 1989 in the Sierra Nevada of western Nevada consisted of tight clumps of seedlings. By fall 1989, 41% of all emergence sites where seedlings survived had resulted from what were originally clumps of seedlings. As Jeffrey pines aged, clumps became smaller, and the frequency of clumps decreased. These seedling clumps and many single seedlings emerged from the scattered caches of seed-hoarding rodents and corvids, and the activities of these animal

A slash pine (Pinus elliottii Engelm. var elliottii) study was established to determine the "optimum" seedling size for use on a flatwoods site in the Coastal Plain physiographic province of Georgia, U.S.A. The optimum seedling is defined as the ideotype that will minimize overall reforestation costs while achieving established goals for initial survival and growth. Initial survival and fourth-year performance were examined in relation to (i) method of site preparation, (ii) herbicide application, and (iii) seedling class (based on root-collar diameter) and to associated establishment costs.

Early in the establishment of Pacific Northwest Douglas-fir ( Pseudotsuga menziesii (Mirb.)

This study was designed to statistically quantify soil moisture, seedling xylem water potential (Ψ), vegetation community, and seedling growth response to six herbicide treatment regimes commonly applied over the first 2 years of establishment. When compared with the control, soil moisture and seedling Ψ increased in response to reductions in competitive cover, allo

The success of a coconut plantation, in terms of its field establishment as well as its future performance, is heavily dependent on the quality of the seedlings used. Coconut nurseries adopt different agronomic practices to produce good quality seedlings. Applying mycorrhizal inoculants is becoming an increasingly common practice in plant nurseries as it facilitates healthy seedling growth resulting in healthy and vigorous seedlings in the nursery, helps to reduce mortality rates of seedlings in the field and reduce water and fertilizer consumption.

Initiation, development, and subsequent growth of seedling root and shoot components can have a direct influence on the quality, adaptation, and survival of seedlings, particularly under stress conditions. Taproot, basal, lateral, and adventitious root components (common indicot plants) each have their own development sequence, growth rate, and may have separate functions for subsequent seedling growth and development. Stresses originating in root components may be expressed in shoots affecting dry matter partitioning between roots and shoots. Partitioning and development of root morphological

Abstract Southern pine seedling silvical requirements for early survival and growth are examined in relation to physical and chemical properties of soils of the southeastern United States. Because of its influence on almost every plant process, soil moisture is the factor of greatest concern. Solar radiation is also critical in the first years because of intense competition for light by seedlings and competing vegetation. The importance of soil aeration is also commonly realized, especially in the coastal plain. However, the threshold soil oxygen levels for survival and growth are not known. W

Bletilla striata (Thunb. ex A. Murray) Rchb. f., a species of perennial herb of orchidaceae that has remarkable effects and high economic value, has been intensively studied by many scholars. Although this herb has many seeds, the germination rate is exceptionally low, which leads to decreased germplasm resources and increased market demand every year. To solve this problem, this study examined the aseptic germination system and the direct seeding technology system. On Murashige and Skoog (MS) medium, 2.0 mg/L 6-benzylaminopurine (6-BA) and 1.0 mg/L naphthylacetic acid (NAA) were added before

Environmental conditions and seedling quality interact to produce complex patterns of seedling survival and growth. Root growth potential (RGP) is one metric of seedling quality that can be rapidly measured prior to planting, but the correlation of RGP and seedling performance is not consistent across studies. Site factors including microsite objects that cast shade and competing vegetation can also influence seedling performance. We examined the effects of RGP, presence/absence of a microsite object, and competition cover on the survival and growth of three native conifers to the Inland North

Cyperus esculentus seeds are often considered irrelevant for C. esculentus spread as their fragile seedlings would not establish or survive in agricultural soils. However, the ever-increasing spread and upsurge of genetically different clonal populations in NW-Europe raises questions about the establishment of C. esculentus seeds and the reproductive performance of seedlings. Indeed, little is known about the potential of C. esculentus seedlings to grow and propagate under outdoor conditions relative to plants grown from tubers. Seeds from different clonal populations were sown outdoors in var
