As the atmosphere warms, precipitation events are becoming less frequent but more intense. A three-year experiment in Kruger National Park, South Africa, found that fewer, more intense precipitation events encouraged woody plant encroachment. To test whether or not these treatment responses persisted over time, here, we report results from all five years of that experiment. Grass growth, woody ...

a pot experiment was conducted in a completely randomized design with five treatment and five replication, in each replication were 6 plants used. the study of zinc sulphate (znso4) application (20 and 40 ppm) and salicylic acid (sa) application (50 and 150 ppm) was compared to the control (distillated water) on growth and flowering petunia hybrid. for each plant was used 100 cc of solution at ...

In recent years, the symptoms of viral diseases such as dwarfism, mosaic, discoloration, necrosis, and circular spots have been prevalent in ornamental plants in parks, gardens, and streets in North Khorasan Province. Tomato ring spot virus (ToRSV) belongs to the Nepovirus genus of Secoviridae family. This virus is a major cause of the infection of ornamental plants in the world. In this study,...

Ornamental horticulture is a very important economic aspect of horticulture and plays a fundamental part in the way humans interact with and modify the environment. Floriculture is in turn a dominant sector of ornamental horticulture. Now, thousands of varieties of cut-flowers, pot plants, hanging plants, bedding plants, shrubs, lawn and turf, ornamental tree and aquatic plants are available to...

1 Stage projection (Lefkovitch) matrices for 21 species of woody plants and 45 herbaceous perennials were extracted from the plant demographic literature or compiled from published data. 2 Each matrix was divided into six regions representing: 1,recruitment ofseeds to the seed pool; 2, recruitment of seedlings or juveniles from current seed production; 3, clonal growth; 4, retrogression, due to...

Nature of Work: The development of new and superior plants helps to stimulate excitement and demand, improve competitiveness and profitability, and ultimately deliver superior and more diverse products to consumers. Numerous sources of novel traits have provided the current diversity in ornamental plants including wild collections of whole plants and seeds, open-pollinated seedling selection, r...

BACKGROUND Data from an ethnobotanical study were analyzed to see if they were in agreement with the biochemical basis of the apparency hypothesis based on an analysis of a pharmacopeia in a rural community adjacent to the Araripe National Forest (Floresta Nacional do Araripe - FLONA) in northeastern Brazil. The apparency hypothesis considers two groups of plants, apparent and non-apparent, tha...

Many people who suffer from seasonal inhal ant allergy in other sections of the United States, come to Florida to escape from offensive pollens at home, inasmuch as airborne pollen grains are commonly declared to be the princi pal exciting cause of such respiratory afflictions, and change of regional residence has in many cases brought relief (7). However, some vic tims who migrate to South Flo...

This report provides a brief review of key findings related to frost resistance in alpine woody plant species, summarizes data on their frost resistance, highlights the importance of freeze avoidance mechanisms, and indicates areas of future research. Freezing temperatures are possible throughout the whole growing period in the alpine life zone. Frost severity, comprised of both intensity and d...

The objective of this study was to assess the growth two woody ornamental plants when subjected different levels weed competition in four container sizes, representing stages production. Ligustrum (Ligustrum lucidum W.T.Aiton) and Japanese holly (Ilex crenata Thunb.) liners were potted individually into 3.8 L, 11.4 24.7 56.8 L containers, respectively. Weed coverage 0%, 50%, 100% each size main...
