San Francisco Orchid Society

The Orchid Conservation Alliance is holding a conservation symposium. Registration and speaker bios, topics & schedule is here: https://orchidconservationalliance.org/orchid-conservation-zoom-posium/

Wanted: young orchid growers. Show your beautiful orchids at the 2022 Pacific Orchid Exposition hosted by San Francisco Orchid Society! Enter plants in the youth category (ages 17 and under) and you might just be awarded the Imperiale Youth Prize, like previous winner Helen Liu. To be considered, bring plants with known names to Plant Entry at the SF County Fair Building tomorrow, Wednesday, 2/23, from 3pm to 8pm, and enter in Section 1200 as a youth exhibitor. For everyone else, be sure to visit the 2022 Pacific Orchid Exposition this coming weekend (2/24-2/27) to see thousands of orchid flowers on display, a plant sale, hands-on horticultural demonstrations, and more. Plus the Conservatory of Flowers is just a 15-minute walk away from the County Fair Building, so you can visit us too!

Join the San Francisco Orchid Society for its 69th Annual Pacific Orchid Exposition from February 25 to 27 at the County Fair Building (1199 9th Avenue) in Golden Gate Park. There will be a preview night on Thursday, February 24. Grab some orchids to spruce up your place this winter! For more information and to buy tickets, visit: https://bit.ly/34VuJdg

If anyone knows the Orchid Zone name to this number, I would be very grateful. Lycaste Z8112 (Z6212 x Z6677) Thanks Tyler

Two awards are available from the AOS. One is for N America only, the other is world wide. To date there have been no nominations for either. Deadline is Dec 1, 2021. Nominations or questions should be sent to [email protected] : Nominations for AOS Conservation Awards Do you know someone or an agency or society who has done something notable in the interest of orchid conservation? You have the opportunity to nominate them for recognition for their efforts! · The Philip E. Keenan Award was established to recognize and reward individuals, groups or Affiliated Societies for outstanding work in the field of orchid conservation, restricted to North America. · The AOS Conservation Recognition Award was similarly established to recognize and reward individuals, groups or Affiliated Societies worldwide for outstanding work in the field of orchid conservation. Two first place awards may be given in each category each year for $500.00 and two second place awards for $250.00. The application period for both of these awards has been extended to 1 December 2021. Application for these prestigious awards should include a nomination statement, a short biography of the proposed recipient when it concerns an individual's efforts, or a short history of the nominated group, organization or Affiliated Society. A concise description (no more than two pages) of the project or endeavor and its effectiveness must be submitted along with the nomination. Several photographs of the conservation work should be included, as well as no more than three letters of recommendation from individuals who are familiar with the work. It is hoped that we can feature these projects in regular articles in Orchids as a reward for the recipients’ good work and to encourage conservation efforts. Nominations or questions should be sent to [email protected].

Luis Valdez and Ken Levi, past President and Vice-President of the Alamo Orchid Society, San Antonio, Texas, just published a book. It’s called “Scandal in the American Orchid Society.” It’s currently available from distributors world-wide.

Oncidium Sharry Baby ‘Tricolor’ Like it’s sister clones, this is a very fragrant flower.

FLOWERING INDUCTION IN NOBILE DENDROBIUM. Dendrobium nobile is a species that crosses with other similar species of the genus Dendrobium, giving rise to a group of hybrids, called "Dendrobium tipo nobile". They are plants with a monsoon climate of centuries-old trees. Of economic importance as flowering plants and not as cut flowers. "Floral induction", also called "floral stimulation", is part of the reproductive state of plants, in which differentiated cells specialize in floral tissues. You can choose meristematic mosaics if they become reproductive structures. It is not a visible morphological alteration, but a histological process that occurs mainly at night. This triggers external factors, such as: the photoperiod and the cold. The technology with which we can manage this process will determine: Whether the plant blooms? How many buttons? Flowering season? Flower location in the pseudobulb (reed) ................ The induction factor: COLD, is generally "a plant developer", especially in tropical plants. In this case, we refer to night temperatures of 10 to 15 ° C. Induction period: 30 to 40 NIGHTS. Keep in mind that I always mean night, darkness. Commercial producers enter their factories in cold chambers at night to artificially induce induction, bagging during the day. Stimulus receiving organ: THE AXILLARY GEMS OF PSEUDOLBS. The stems originated from the last spring bud in the "modern" Dendrobium or the penultimate spring, in the "old" dendrobium. This is a DETERMINED induction, and you yourself must have the prerequisites for induction: 1-MATURATION: the plants in a juvenile state in bloom must be ripe. We know that they are mature, when there is also the so-called "flag". It marks the cessation of vegetative and reproductive status. It is desirable that this moment is before December-January in the southern hemisphere, otherwise the induction will occur only in the upper third of the poles. To achieve proper maturation, the following are important: a positive daily temperature range of 10 to 15 ° C, abundant irrigation, adequate fertilization and correct lighting. An excess of nitrogen will keep the plant in a vegetative state, not appearing at the typical time of time and forming at the tip of the canes. 2-TRAINING: are the changes (development) that the cane must undergo once MATURE, to be sensitive to the COLD. Son: thickening (due to the accumulation of water and nutrients), yellowing and extreme roundness. The induction that concerns us is a REVERSIBLE process, the axillary yeasts are induced and undifferentiated, they can go to the vegetative state, giving rise to Keikis (plants from the botanical point of view). This will occur when daytime temperatures are above 25 ° C for more than 20 days. If we decide to have a vegetative induction, it should happen in late spring and when we fertilize with a lot of nitrogen. About this technology and others, little is written, published or told the truth. Much hides and lies. They are technological and profitable secrets.
