List Of Invasive Plant Species In New South Wales
Numerous plants have been introduced to the state of New South Wales, Australia during the past two centuries, and many of them have become invasive species or noxious weeds which by definition compete with native plants and suppress the growth of indigenous populations. NSW has over 340 weeds, though only one-third are considered noxious, which were purposefully introduced as garden and farmland plants, and thus had escaped. They generally consist of agricultural, scrub, aquatic, roadside and allergenic weeds. Weeds threaten more than 40% of NSW threatened species (which are predominantly plants) and around 90% of endangered ecological communities. An excess of $50 million of public money (half which come from state government) is currently being spent on weed control. Despite the efforts, the control is not keeping up with their invasiveness, and the NSW Government has granted that it is unlikely to surpass its 2015 goal of ‘a reduction in the impact of invasive speciesâ ...

Limnobium Laevigatum
''Limnobium laevigatum'' is a floating aquatic plant, and is a member of the family Hydrocharitaceae. Common names include West Indian spongeplant, South American spongeplant and Amazon or smooth frogbit. This plant was introduced to North American waterways through use in aquariums and aquascapes. Plant origin and distribution Spongeplant originates from fresh water habitats of tropical and subtropical Central and South America. In California it has been introduced as an ornamental pond plant, and has escaped into greater waterways including areas surrounding Redding and Arcata, the Sacramento river delta and the San Joaquin River, and ponds and irrigation canals. Description ''Limnobium laevigatum'' is a floating aquatic plant, which can be mistaken for water hyacinth ('' Eichornia crassipes'') due to their superficial similarity. Juvenile plants grow in rosettes of floating leaves that lie prostrate upon the water surface, a distinguishing character of the juvenile plant ...

Biosecurity Act 2015
The ''Biosecurity Act 2015'' is an Act of the Parliament of Australia which manages biosecurity risks in Australia. It was enacted on 16 June 2015, after the Bill was passed with bipartisan support on 14 May 2015. It covers both agricultural and human medical biosecurity risks, including epidemics and pandemics, and is designed to contain and/or deal with any "diseases and pests that may cause harm to human, animal or plant health or the environment" in Australia. The application of the Act was particularly tested during the COVID-19 pandemic in Australia. History The Act replaced most of the ''Quarantine Act 1908'', which was wholly repealed on 16 June 2016 by the ''Biosecurity (Consequential Amendments and Transitional Provisions) Act 2015''. Text was copied from this source, which is available under Creative Commons Attribution 4.0 International License The new Act is a major reform of the ''Quarantine Act'', in particular in its strengthening and modernising the existin ...

Senna Pendula
''Senna pendula'', also known as Easter Cassia, Christmas Senna, winter Senna, climbing Cassia, golden shower, pendant Senna and valamuerto, is a plant of the Fabaceae family with a shrub habit that is native to South America. It used in various parts of the world as an ornamental plant and is an environmental weed in Australia. The flowers are yellow and the name ''pendula'' means 'pendulous' or 'drooping'. Description It is a fast-growing, spreading, scrambling or erect shrub that reaches 2–4 metres in height with multi-branched and arching stems and branches. Its single-compound, hairless leaves feature three to six duos of wide leaflets that are 1–5 cm long and 5–20 mm wide with rounded tips and salient yellowish margins. Its bright yellow flowers, which are about 3 cm across, have five large petals and are foaled in leafy clumps at the tips of the branches. The fruit is in a cylindrical pod (10–20 cm long and 6–12 mm wide) that hang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anredera Cordifolia
''Anredera cordifolia'', commonly known as the Madeira-vine or mignonette vine, is a South American species of ornamental succulent vine of the family Basellaceae. The combination of fleshy leaves and thick aerial tubers makes this a very heavy vine. It smothers trees and other vegetation it grows on and can easily break branches and bring down entire trees on its own. Description ''Anredera cordifolia'' is an evergreen climber that grows from fleshy rhizomes. It has bright green, heart-shaped, fleshy shiny leaves 4–13 cm long. Wart-like tubers are produced on aerial stems and are a key to identifying the plant. From late summer to autumn, it produces masses of small, fragrant, cream-coloured flowers on dependent racemes, which may be up to in length. The plant spreads via the tubers, which detach very easily. Reproduction ''Anredera cordifolia'' can reproduce through the proliferation of tubers and also from rhizome fragments that may be broken off. Although this sp ...

Plant Propagation
Plant propagation is the process by which new plants grow from a variety of sources: seeds, cuttings, and other plant parts. Plant propagation can also refer to the man-made or natural dispersal of seeds. Propagation typically occurs as a step in the overall cycle of plant growth. For seeds, it happens after ripening and dispersal; for vegetative parts, it happens after detachment or pruning; for asexually-reproducing plants, such as strawberry, it happens as the new plant develops from existing parts. Plant propagation can be divided into four basic types: sexual, asexual (vegetative), layering, and grafting. Countless plants are propagated each day in horticulture and agriculture. The materials commonly used for plant propagation are seeds and cuttings. Sexual propagation Seeds and spores can be used for reproduction (e.g. sowing). Seeds are typically produced from sexual reproduction within a species because genetic recombination has occurred. A plant grown from seeds may ...

Ipomoea Cairica On Erythrina Crista-galli By Downfall Creek 7th Brigade Park Chermside P1060369
''Ipomoea'' () is the largest genus in the plant family Convolvulaceae, with over 600 species. It is a large and diverse group, with common names including morning glory, water convolvulus or water spinach, sweet potato, bindweed, moonflower, etc. The genus occurs throughout the tropical and subtropical regions of the world, and comprises annual and perennial herbaceous plants, lianas, shrubs, and small trees; most of the species are twining climbing plants. Their most widespread common name is morning glory, but some species in related genera bear that same common name and some ''Ipomoea'' species are known by different common names. Those formerly separated in ''Calonyction'' ( Greek "good" and , , , "night") are called moonflowers. The name ''Ipomoea'' is derived from the Greek , (, ), meaning " woodworm", and (), meaning "resembling". It refers to their twining habit. Uses and ecology Human uses of ''Ipomoea'' include: *Most species have spectacular, color ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cultivar
A cultivar is a type of cultivated plant that people have selected for desired traits and when propagated retain those traits. Methods used to propagate cultivars include: division, root and stem cuttings, offsets, grafting, tissue culture, or carefully controlled seed production. Most cultivars arise from purposeful human manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word ''cultivar''''Cultivar'' () has two meanings, as explained in ''Formal definition'': it is a classification category and a taxonomic unit within the category. When referring to a taxon, the word does not apply to an individual plant but to all plants that share the unique characteristics that define the cultivar. was coined as a term meaning "cultivated variety ...

Cuttings (plant)
A plant cutting is a piece of a plant that is used in horticulture for vegetative (asexual) propagation. A piece of the stem or root of the source plant is placed in a suitable medium such as moist soil. If the conditions are suitable, the plant piece will begin to grow as a new plant independent of the parent, a process known as striking. A stem cutting produces new roots, and a root cutting produces new stems. Some plants can be grown from leaf pieces, called leaf cuttings, which produce both stems and roots. The scions used in grafting are also called cuttings. Propagating plants from cuttings is an ancient form of cloning. There are several advantages of cuttings, mainly that the produced offspring are practically clones of their parent plants. If a plant has favorable traits, it can continue to pass down its advantageous genetic information to its offspring. This is especially economically advantageous as it allows commercial growers to clone a certain plant to ensure consiste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
