It was great seeing all the Plant of the NEXT MEETING Year results. It seems we all grow plants quite differently. For Marcia Tatroe: 2018, it would be great to get more information on how each "Rockin’ with Cacti and Succulents" individual grows their plants so that we might discover what Sunday January 14, at 1:00 pm makes these plants grow best. To meet this aim, we are (Program starts at 1:30pm) developing a study as a club-wide project. Until you receive the questionnaire, please make note of the size of your 2018 plant of the year (Thelocactus bicolor var. parras) and its growing REFRESHMENTS FOR JANUARY conditions. For those of you who did not attend the Potluck, a As the last meeting was the Pot-Luck we don't few plants will be available at the January meeting. have a list of refreshment volunteers. There is still a chance to receive a free one-year So if you would like to bring something to the membership to the CSSA if you attend the meeting in January next meeting please do so - thanks! to put your name in for the drawing.

Colinas de la Normal, Guadalajara, Jalisco, México The ability to regenerate a plant from a single cell is known as totipotency, and such phenomenon occurs not only in in vitro tissue and cell culture but in specialized somatic cells that are part of whole plants in ex vitro natural conditions, constituting this asexual or vegetative processes their only means of reproduction [1]. A large number of studies have been conducted in order to understand the mechanisms by which shoots, plantlets and vegetative propagules are produced. According to the first studies reported by Yarbrough [2, 3], in the fern species Camptosorus rhizophyllus (which has two different kinds of leaves), shoots are produced at the tip of long acuminate leaves, while in the species Tolmiea menziesii shoots are originated in a notch near the junction of the petiole and the leaf blade; in both cases, the shoots are produced from meristematic tissue and once they are mature are naturally detached from the leaf and fall to the ground originating a new plant.

  • Kalanchoe Daigremoniana - Mother of Thousands Plant
    Kalanchoe daigremoniana - Mother of Thousands plant: From Wikipedia: Scientific classification Kingdom: Plantae [Angiosperms; Eudicots; Core eudicots] Order: Saxifragales Family: Crassulaceae Genus: Kalanchoe Section: Bryophyllum Species: K. daigremontiana Binomial name: Kalanchoe daigremontiana Raym.- Hamet & H.Perrier Synonyms Bryophyllum daigremontianum Raym.-Hamet & H.Perrie Common names: Devil's Backbone, Alligator Plant, Mexican Hat Plant, Mother of Thousands. Mother of Thousands is a succulent plant native to Madagascar. This plant is distinguished by its ability to propagate via vegetative propagation. All parts of the plant are poisonous, which can even be fatal if ingested by infants or small pets. Plants of the genus Kalanchoe able to propagate vegetatively are often included in section Bryophyllum, therefore Kalanchoe daigremontiana Hamet & Perrier is synonymously called Bryophyllum daigremontianum (Hamet & Perrier) Berger. (Some botanists consider Bryophyllum a distinct genus.) Plants reach up to 1 m (3 feet) tall with opposite, fleshy oblong-lanceolate "leaves" that reach 15-20 cm (6-8 inches) long and about 3.2 cm (1.25 inches) wide. These are medium green above and blotched with purple underneath. The margins of these leaf-like organs have spoon-shaped bulbiliferous spurs that bear young plants. The plantlets form roots while on the plant. The "leaves" are actually short, determinate, leaf-like branches that can be termed phylloclades or cladodes. Adult plants can also develop lateral root structures on its main stalk, as high up as 10-15 cm from the ground. The plant has several nodes with two or three leaves on each node. The upper leaves of the plant tend to develop into disproportionately large structures, causing the main stalk to bend downwards and the lateral roots to take up root of their own, anchoring into the soil and eventually developing new primary stalks which establish themselves as independent plants.

The aim of this study, therefore, was to characterize the reproductive system of K. laetivirens through analyses of floral morphology, trophic resources and floral visitors. Floral structures, pollen / egg ratio, in vitro pollen germination, pollen grain structure in scanning microscopy and the availability of trophic resources by the evaluation of potential and instant nectar were described.

In this study, we assess the gastroprotective effects of the hydroethanolic extract (HE) and ethyl acetate fraction (EAF) from Kalanchoe pinnata leaves against an ethanol/HCl-induced ulcer model in rats. The HE reduced gastric lesions by approximately 47% (400 mg/kg). A significant inhibition of the gastric lesions by 50% was observed after pretreatment with the EAF (200 mg/kg). Quercetrin and quercetin 3-O-α-L-arabinopyranosyl-(1→2)-α-L-rhamnopyranoside were isolated and identified in the flavonoid fraction (EAF) by HPLC and NMR analyses because this fraction showed the highest gastroprotective effect. This fraction demonstrated high antioxidant activities (CE50=41.91 µg/mL) by DPPH in comparison with Trolox® and 11.33 mmol Trolox® equivalent by ORAC. In conclusion, the HE and FAE from K. pinnata displayed gastroprotective activity in rats, most likely due to the presence of flavonoids. Uniterms: Gastric ulcer/study/rats.
