Miracle-Gro’s African Violet Potting Mix is excellent for many young plants. Selection and mutagenesis in cultured african violet plantlets book offers a slightly acidic composition that drains well and is full of rich organic material, making it useful for more than African violets.

I’ve used it for other small projects when in a bind and it works just fine. To stir it up, any household mixing bowl will do. In African violet, Agrobacterium-mediated transformation is affected by the Agrobacterium strain, selection marker, and cutting-induced wounding stress.

Somaclonal variation, which arises in tissue cultures, can be problematic in maintaining true-to-type clonal material, but may be a useful tool for obtaining variation in flower by: 1.

African Violet Foliage Types. European settlers discovered African violet (Saintpaulia ionantha) in east African forests in Sold as a houseplant by the late s, African violets gained.

African Violet plants exhibiting the multiflorescence trait with at least one leaf axil that produces two or more flower stems are provided. African Violet plants carrying the multiflorescence trait bloom continuously. The multiflorescence trait has been successfully bred into diverse African Violet plants.

The multiflorescence trait can be combined with many desirable traits including Author: Holtkamp Sr Reinhold. Plantlets of Anubias congensis N.E. Brown cultured on MS medium were irradiated with gamma rays for both acute and chronic treatments of 0, 20,40, 60, 80 and Gy at a dose rate of Gy/hr.

African violets are cheery little plants that don’t appreciate a lot of fuss and muss. In other words, they’re the perfect plant for busy (or forgetful) folks.

Dividing an African violet – or separating African violet “pups” – is an easy way to generate more plants to spread around your house, or to share with lucky friends.

Answer: Most African violets can be successfully propagated by leaf, producing plants that are genetically identical to the leaf donor.

It normally doesn’t matter which leaf is used for propagation, since all fo the cells of one leaf are genetically identical to the cells of any other. African Violet mutations or “Sports ” happen fairly often and the results can be delightful, disappointing or anything in-between. Starter Plug Plant.

The example of a 87 pins. Received: 9 October, Accepted: 26 April, Invited Review Bioremediation, Biodiversity and Bioavailability © Global Science Books In Vitro Mutagenesis and Selection in Plant Tissue Cultures and their Prospects for Crop Improvement.

African violet (Saintpaulia ionantha H. Wendl.) (Gesneriaceae) is a popular ornamental pot plant that is easy to culture ex vitro and in vitro relative to other herbaceous quality makes it an ideal system for in vitro regeneration experiments.

This review summarizes the studies that have been conducted on the in vitro culture and micropropagation of this plant. Some African violets have even been to the moon: The EverFloris series grew from seeds that flew to space on a space shuttle.

The seeds spent six years in orbit, then returned to Earth and were planted, resulting in several interesting mutations including bigger plants (50% bigger!), different bloom clusters, and continuous, year-round blooming. African violets are very easily propagated from leaf.

Even inexperienced growers can quickly produce additional plants and expand their collection. Step 1: Remove and trim leaf. Remove a fresh leaf from the plant that you wish to propagate.

It’s best to use a mature leaf, but not one that’s old and tough. Using a sharp knife or razor, trim away. Each meeting has a Trading Table and members are able to purchase all the supplies they will need for growing African violets and other Gesneriads as well as a selection of plants.

There is a library of books about African violets and other Gesneriads that are listed on the web based index and available to members at meetings. Sources of variations detected in plant tissue culture.

Tissue culture is an efficient method of clonal propagation; however, the resulting regenerants often has a number of somaclonal variations (Larkin and Scowcroft ).These somaclonal variations are mainly caused by newly generated mutations arising from tissue culture process (Sato et al.

This technique can be used to determine the ploidy of African violet plants from anther culture. Roots obtained from leaf cuttings (such as African violets, rooted in distilled water of dilute nutrient solution for 2–3 weeks) can be used.

Place root tips in 5 N HCl for 10 min at room temperature. Rinse three times in distilled water.

January/February African Violet Magazine, pgs By Dr. Charles Cole. Providing good nutrition for our African violet plants involves more than purchasing a fertilizer product and applying it to the plants. We need a basic knowledge of what a plant needs and how a specific nutrient effects a plant under a given set of conditions.

During the early years, African violets were predominantly a greenhouse plant, rather than a houseplant. From untilvarious writings in horticultural and botanical publications indicate that African violets were mainly grown under glass structures.

A favorite place to exhibit these plants was near the edge of staging in public and private greenhouses and at flower shows.

The only transgenic African violet plants generated to date with horticulturally useful traits are tolerant to boron (heavy metal) stress, or bear a glucanase-chitinase gene.

Discover the world's. My African violet plants arrived a day earlier than expected, were wrapped nicely and carefully, and transferred well into a slightly larger pot. I ordered the special African Violet dirt and fertilizer as well.

They were pink and dark purple, very pretty, healthy (there are even little buds on them) and I am very happy with them/5(). Mutagenesis of polyploid plant species is difficult. Because most mutations are recessive, plants must be homozygous to display the trait.

Polyploid conditions can further complicate the process of reaching homozygosity for the mutation, so must be selfed for additional generations to ensure presence of the mutation. The Future of mutation breeding. African Violet Care: Basic Summary Light: Moderate to bright, indirect, indoor light.

Watering: Keep soil moist to dry, and allow soil around roots to dry out before watering to encourage from the bottom with room temperature water by placing the plastic grower's pot in water, and allowing the plant to absorb the water (not more than 30 minutes).

Saintpaulia (family Gesneriaceae), commonly known as African Violet, is a popular houseplant as a result of its compact size, tolerance of shaded conditions, ease of vegetative propagation, and potential to flower year round.

To date ≈20, varieties have been produced globally by conventional hybridization techniques and spontaneous mutation, and annually, several hundred new cultivars are. To initiate cultures, various explants of African violet (Saintpaulia ionantha H.

Wendl) were excised from 2-month-old intact plants which were grown in greenhouse. The flower buds ( mm), leaf (10 x 10 mm), petiole (10 mm) and peduncle (10 mm) were used as explants for in vitro studies [ 9 ].

After several years, an African violet can grow into a shape similar to that of a palm tree: the lower leaves tend to yellow and drop as the crown of the plant continues to grow upward.

When the foliage crown reaches a couple of inches above the rim of the pot, you should rejuvenate your ing African Violet How-To1. Gently tap the sides of the pot against a hard surface to loosen.

Once considered stuffy and conventional, today's African violet might be the prom queen of houseplants. African violets (Saintpaulia) bloom nearly year-round.

Flowers might be simple, frilly, or shaped like wasps, and they come in a rainbow of brilliant colors. See how to turn dainty pots of African violets into stunning arrangements with big impact.

African violets (Saintpaulia ionantha) – named after Baron Walter von Saint Paul, who brought them from East Africa – are one of the world’s most popular houseplants of all time. They are. Although African violets (Saintpaulia ionantha) hail from Africa, lots of people in the United States grow them as indoor are easy care and beautiful, blooming most of the year, but that doesn’t make them free of aphids or other pests.

When you find African violet pests attacking your favorite potted plants, you need to take appropriate action. Grice, Mel // African Violet Magazine; Mar/Apr, Vol. 63 Issue 2, p The article discusses the Gloxinella lindeniana specie of the Gesneriad family of plants, which includes African violets.

The specie is originally collected in Ecuador. The plant was named after Belgian nurseryman and collector Jean Jules Linden.History of the African Violet: The African Violet is a very common houseplant. African Violets, are also known as, Saintpaulia Ionantha.

The African Violet was founded in in Northeast Tanga and German East Africa. The man who found the plants was named, Saint Paul. Once Saint Paul found them, he gave some to his father who lived in Germany.

After a total of 30 days culture in the media, plantlets with 4–6 leaves and – cm in height were removed from the jars. The agar on the roots was gently removed by rinsing in tap water, and transplanted into a 6 cm plastic pot with sphagnum peat-based medium consisting of Canadian peat, vermiculite, and perlite in a 3: 1: 1 ratio.
