  1. African violet (Saintpaulia ionantha H. Wendl) is one of the most easily and commonly tissue-cultured ornamental plants. Various growth, photosynthetic and biochemical paramete rs and activities of antioxidant enzymes and dehydrins of Photosynthetic rate and transpiration rate were measured with a portable LCi photosynthesis system (AD
  2. The chemistry and medicinal uses of Saintpaulia have been poorly explored. The secondary metabolite, cyanidin, was identified in the leaves of in vivo and in vitro grown S. ionantha microshoots, and cyanidin content for in vivo and in vitro extracts was 98.16 and 85.04 mg/g dry tissue, respectively (Al-Sane et al., 2005)
  3. To start with regeneration protocols were standardised through multiple shoot bud production from leaf and petiole explants using growth regulators BAP and NAA. BAP at 2.5 mgl -1 and NAA at 1 mgl -1 gave the highest number of shoot buds (40) in leaf explants

combination of growth regulators. This response was quantified at different stages of micropropagation and evaluated the survival rate at the stage of plantlets acclimatization. First sings of morphogenesis were shown 33 days after cultivated. It achieved high rates Plants grown under RED and BLUE films showed a decrease in the main growth parameters evaluated. Net photosynthetic rate (mg CO 2 m-2 s-1) were signifficant lower under RED and BLUE cover plastic. These results determined a lower photoassimilated accumulation (expressed as plant dry weight) at RED and BLUE treatments

  4. The behaviour of eleven Saintpaulia ionantha (H. Wendl.) genotypes in protoplast culture was compared. Isolation of protoplasts from young shootlets regenerated in vitro on leaf explants, yielded 0.7 to 1.8 × 106 protoplasts per gram fresh weight. In all cultivars and breeding lines tested, cell divisions were observed
  5. The African violet (Saintpaulia ionantha H. Wendl.) worldwide is a highly prized ornamental potted plant where demand for it generates high revenues. However, the constant rise in the price of chemical inputs requires finding alternative management strategies where production costs of the crop are kept in line with local and global competitiveness

These media consisted of MS basal salts with 5 hormonal treatments (control (hormon
  7. Micropropagation is an important tool for rapid multiplication and the creation of genetic variability in African violets (Saintpaulia ionantha Wendl.). Successful in vitro propagation depends on the specific requirements and precise manipulation of various factors such as the type of explants used, physiological state of the mother plant.

African Violet Care. African violets will thrive in bright, warm and humid conditions. Keep water from touching their leaves or it will leave brown spots. Remove dead flowers and leaves as soon as you see them to encourage a healthier plant. Regularly check the soil and plant to make sure there is no accumulation of dead leaves This is the case of African violet (Saintpaulia ionantha Wendl.), where a generalized temperature response for leaf growth and development has not been developed yet. The objective of this study was to develop a generalized nonlinear temperature response function for leaf appearance rate and leaf elongation rate in African violet (Saintpaulia ionantha), are sensitive to chilling tempera-tures. Symptoms of chilling injury include the cessation of protoplasmic streaming, diminished seedling vigour, reduced plant growth, increased cellular leakage, impaired photosynthesis, excessive water loss, increased susceptibil-itytocertaindiseases,andenhancedsenescence.Forexam

Saintpaulia grows well at 50% to 70% relative humidity. Low humidity in Florida in the spring and fall can cause flower petal burn. Humidity may be raised by wetting walkways and underneath benches with a hose. Light intensity is a very important factor in production of quality Saintpaulia. Light recommendations vary by cultivar and season, but a range of 800 to 1,200 foot candles is satisfactory Plant Growth Rate: Moderate: Planting Remarks: Needs a cooler growing environment to do well (28'c). Will grow and bloom well if placed in an area receiving morning sun in air-conditioned areas; for non air-conditioned areas, plants should be placed in areas with good ventilation, and very bright, indirect light. Fertilizin Saintpaulia ionantha Wendl. (African violet) is one range with relatively low success rate (3). In contrast, particle bombardment has proved to surpass such growth chamber (diurnal cycle of 16 h light of 25 μE.m2s-1 at 25°C followed by 8 h dark period at 22°C). 3.3. Histochemical GUS Stainin A regeneration procedure was developed for in vitro grown African violet (Saintpaulia ionantha Wendl.).

How to Grow African Violets - West Coast Seed

African violet ( Saintpaulia ionantha Wendl.; Gesneriaceae) is a commercially important indoor ornamental plant species highly valued in many parts of the world. Thousands of Saintpaulia cul-tivars have been selected for plant size, ß oral colors, leaf shapes and pattern, growth, uniform ß owering, and better performance as a house plant African Violets. The African violet ( Saintpaulia ionantha) is a part of the Gesneriaceae family and is known to be one of the best house plants. It is known to be s native plant to Kenya and Tanzania in east Africa, but is known to be concentrated in the Nguru mountains of Tanzania. They have thousands of different varieties and every year.

Except for the species Saintpaulia ionantha as a whole, which is near threatened, all of the other Saintpaulia species and all of the subspecies of S. ionanatha are in one of the three threatened. Directions to Grow African Violets. African violets (Saintpaulia ionantha) produce purple, blue, pink or white blooms coupled with thick, fuzzy green leaves. Often grown indoors as houseplants. Answer: Many of the current hybrids originated from crosses made with Saintpaulia ionantha and with S. confusa (now considered to be a subspecies of S. ionantha). Recently, DNA studies established that many species previously identified as separate species were in fact all subspecies of Saintpaulia ionantha (and ionantha is now classified as a. A direct relation between growth due to auxin treatment and rate of respiration has been found i.e., greater the growth, higher is the respiration. In leaf segments of various plants such as Saintpaulia ionantha, Bryophyllum sp and Begonia sp., the kinins stimulate the production of buds Growth analysis was used to calculate the relative growth rate (RGR), net assimilation rate (NAR), and leaf area ratio (LAR) of plants by using the total dry weight and leaf area of the plants sampled on November 17, 2010 (1 day before CO 2 enrichment was initiated), and those sampled on January 22, 2011 (when CO 2 enrichment ended), according.

Introduction. African violet (Saintpaulia ionantha H. Wendl), a member of the Gesneriaceae family, is a popular commercial ornamental plant and holds good export potential as a pot flower in many countries.Micropropagated plants are associated with several physiological and anatomical abnormalities during in vitro growth such as low photosynthetic capacity, nonproper functioning of stomata. Cryopreservation of African violet via encapsulation-dehydration, vitrification, and encapsulation-vitrification of shoot tips was evaluated. Encapsulation-dehydration, pretreatment of shoot tips with 0.3 M sucrose for 2 d followed by air dehydration for 2 and 4 h resulted in complete survival and 75% regrowth, respectively. Dehydration of encapsulated shoot tips with silica gel for 1 h.

Variegated African VioletsLatin: Saintpaulia ionantha Variegated Clones. African violets are essentially 20th century plants, first discovered along ravines in deep undergrowth about 1890 in the wilds of equatorial east Africa. Most of the 2000 named selections of African violets now available are derived from the first species discovered. African violets that you buy are almost certainly hybrids, generally of one main species (Saintpaulia ionantha). The native habitat of this species, in the Tanga region of Tanzania in Africa, gives clues to its culture. Most houseplant fertilizers will work, and there are some formulated just for violets. Use at the rate and timing. growing foliar embryos, Saintpaulia ionantha (African violet) food production and the rate of propagation will be slower. The leaf, when separated from its parent plant, will be highly susceptible to desiccation and it is necessary to minimize this by controlling the environment
