Tillandsia psuedobaileyi forma alba - Nalda Wilson ionantha v. stricta ‘Sumo’ <funckiana; tomasellii > ionantha > Tillandsia psuedobaileyi forma alba Pics by Jodie Smith notes from “Tillandsia 11” by Paul Isley 2009 page 104. !“Tillandsia pseudobaileyi grows as an epiphyte from Mexico to Nicaragua at elevations of near sea level to over 1,500m. It is a myrmecophyte (plants adapted to live in symbiosis with ants and/or ant colonies) that is easy to recognise because the inflated base is similar in appearance to an onion. Besides green, the basic colour of the plant is amethyst but since most of the plant is densely covered with finely appressed trichomes T. pseudobaileyi also has a frosted, silvery appearance. The leaves are striated longitudinally with thin amethyst lines. Overall it is a striking species, albeit one has to look closely because the colours and markings are subtle. Tillandsia pseudobaileyi flourishes in brightly lit outdoor patio or garden situations but needs frequent watering in dry climates and a standard feeding program through Fall. Tillandsia pseudobaileyi is an ageotropic species, so it grows well horizontally even upside down as do other myrmecophytic species.” !

Nigel showed beautiful Hawaii, the huge nurseries and plants that were imported. His second talk was a kaleidoscope of colour - some of the very mouthwatering plants that will be released at ‘Sunny Broms’ conference in Caboolture on 31/3 to 2/4/2017. There were lots of ‘ohs’ & ‘ahs'. Greg Aizlewood took us to Ecuador, now everyone wants to go! Anil Ghodke explained tissue culturing. Bob showed different forms of tillandsias - after he had cooked us kebabs for lunch. Thank You to the Attendees, the Speakers, Plant Sellers & the Helpers who lifted & carried ‘stuff’. Special thank you to Kelly & Sharron who were marvellous, always there, doing. Mass Plant Production by Tissue Culture Presented by Anil Ghodke! Tissue culture technology involves rapid multiplication of plants on a nutrient medium containing growth hormones under sterile conditions. These plant cultures are kept under controlled conditions of light and temperature suitable to the particular plant species, to yield plantlets in mass numbers. Procedure Flow Chart The section to be tissued can be part of the plant leaf, or buds, or cells from other parts of the plant, this is then called the ‘explant’. Bromeliad tissue is usually taken from the meristem. The working environment must be kept completely sterile throughout the whole procedure. Surface sterilisation of the ‘explant’ is the most important and sensitive step in plant tissue culture. Inappropriate concentrations of sterilants have a lethal effect on cell division and restrict growth and development of the ‘explant’. Therefore, suitable concentration, and combination and duration of sterilant exposure is essential to raise in vitro cultures successfully. Media is a mixture of macro nutrients & micro nutrients plus organic substances plus growth regulators & inert materials such as agar-agar. Each different plant requires differing ratios of ingredients. Surface sterilisation of the ‘explant’ is the most important and sensitive step in plant tissue culture. Inappropriate concentrations of sterilants have a lethal effect on cell division and restrict growth and development of the ‘explant’. Therefore, suitable concentration, and combination and duration of sterilant exposure is essential to raise in vitro cultures successfully. The bud was removed from the mother plant for transfer into tissue culture and in just a few weeks the bud started to multiply on the nutrient media. They are then separated. Plants growing in the growth room in a controlled environment Tissued plants in flask Vriesea plantlets Pretreatment before planting After pretreatment Planting in trays Growing strongly Established tubestock The advantages of tissue culture* Creation of a large number of clones of selected elite plant varieties. *Large numbers of identical plants can be propagated in short amounts of time. * Overcomes seasonal restrictions of propagation through cuttings. * Easy international exchange of sterilised materials. Anil uses new techniques and invests in new equipment to keep standards high as he not only provides Australian growers but has contracts with chains of garden centres in Europe. // (Remember to repot each three months as you would seedlings.

Three loads of plants, many working hands & proof bromeliads can certainly brighten a spot. Thanks Bob, Matt, Jodie, Kelly, Paul and 2 Council staff It was fun & looks even better in just the few weeks.

Sharon’s Mum & Sharon ^ Sharon Lee ! Plant grower extraordinaire from Rubyvale, a proud Queenlander. (On Tillnuts) Q: Sharon Lee - Doing the rounds this morning I noticed a Tillandsia glabrior inflorescence was stuck. Bit of gently prising with tweezers has released it (hopefully it will straighten). Is likely to be a humidity issue? A: Andrew
