Unveiling the germination requirements for Cereus hildmannianus (Cactaceae), a potential new crop from southern and southeastern Brazil Acta Botanica
Becker,Rafael; Ri,Leandro Dal; Farias-Singer,Rosana; Singer,Rodrigo Bustos.
ABSTRACT Cereus hildmannianus K. Schum is a columnar cactus native to South and Southeast Brazil. The cultivation of this species seems justifiable for several reasons: its fruits are spineless and edible; it is not threatened with extinction; it naturally occurs in Pampa and Atlantic Forest under non-xeric conditions that may be unsuitable for the cultivation of other tropical cacti; and the plants are pollinator-dependent and so should benefit from native pollinators. This study aimed to test seed germination of C. hildmannianus with samples collected at three different localities in southern Brazil, as a necessary step preceding any attempts of management and domestication. Seeds were exposed to temperatures of 20° C, 25° C, 30° C and room temperature....

Fresh or dehydrated spineless cactus in diets for lambs Animal Sciences
Andrade, Solano Felipe Just de; Batista, Ângela Maria Vieira; Carvalho, Francisco Fernando Ramos de; Lucena, Rodrigo Barros de; Andrade, Rafael de Paula Xavier de; Lima Júnior, Dorgival Morais de.
The objective was to evaluate the effect of partial or total replacement of Tifton 85 hay with fresh or dehydrated spineless cactus on performance and body weight components of sheep. Thirty hair lambs, with 19 kg ± 0.35 kg initial weight, were randomly divided into five treatments, namely: Tifton 85 Hay (HA); Tifton 85 Hay + fresh spineless cactus (HAFC); Tifton 85 Hay + dehydrated spineless cactus (HADC); fresh spineless cactus (FC); dehydrated spineless cactus (DC). In addition to the spineless cactus and hay, the complete mixture contained soybean meal, mineral salt and limestone in all treatments. Animals were confined for 75 days and then slaughtered. The weight of body components was recorded. Dry matter intake, total digestible nutrients intake and...

Aprovechamiento tradicional de cactáceas y agaváceas en los municipios de Tepeyahualco de Cuauhtémoc y Huitziltepec, Puebla Colegio de Postgraduados
Martínez Vásquez, Esteban.
Las cactáceas y agaváceas son dos familias botánicas de gran importancia por el número de especies que presentan, y por los múltiples usos que han tenido entre la población de México. En los municipios de Tepeyahualco de Cuauhtémoc y Huitziltepec, diversas especies de cactáceas y agaváceas se han utilizado desde tiempos inmemoriales, con lo que se han generado importantes conocimientos sobre su manejo, producción y reproducción, aunque en la actualidad existen factores que están interfiriendo en el proceso de transmisión de éstos, lo cual amenaza la reproducción de los agroecosistemas y vulnera la diversidad de distintas especies de estas plantas. Este trabajo tuvo como objetivos registrar y sistematizar el conocimiento tradicional que aún mantienen los...

Conditions for the germination and the early growth of seedlings of Polaskia chichipe (Goss.) Backeberg and Echinocactus platyacanthus Link and Otto fa. grandis (Rose) Bravo-Hollis (Cactaceae): (with 2 tables & 2 figures) Phyton
Rosas-López,Ulises; Collazo-Ortega,Margarita.
The effect of different combinations of chemical scarification, soaking and substrates (ex vitro and in vitro) on seed germination ofPolaskia chichipe (Goss.) Backeberg and Echinocactus platyacanthus Link & Otto fa. grandis (Rose) Bravo-Hollis, collected in the Tehuacan Valley, Mexico, were studied. The P chichipe seeds did not require either chemical scarification or soaking, whereas E platyacanthus required chemical scarification with strong acids. Growth and maintenance of the seedlings was evaluated in two different concentrations of Murashige-Skoog medium (50% and 100% of their components). It was found that MS 50% stimulated germination in both species and promoted seedling growth.

Mixed reproduction systems in Opuntia monacantha (Cactaceae) in Southern Brazil Rev. Bras. Bot.
Lenzi,Maurício; Orth,Afonso Inácio.
The Cactaceae have morphological and physiological adaptations associated with their life histories that are reflected in different modes of reproduction and multiplication. The reproductive phenology, preferential reproductive mode, and the sexual and asexual multiplication of Opuntia monacantha were investigated between 2003 and 2006 in two restinga (sandy coastal) environment in Southern Brazil to determine the adaptive values of its reproduction modes. Flowering was annual and occurred continuous for approximately 100 days between the months of September and January, with a few flowers opening per day per individual (but many in the whole population). Facultative xenogamy was identified as the preferential sexual system, with the highest levels of...

Cereus peruvianus (Koubo) new cactus fruit for the world Rev. Bras. Frutic.
Mizrahi,Yosef.
Several different species of the columnar cacti of the genera Stenocereus and Pachycereus, were introduced into different semi-arid ecozones in Israel and most of these efforts were of disappointing outcomes, the only exception being the Cereus peruvianus (L.) Miller,which bore plenty of fruits, some of them of good taste. The original seeds of this plant were obtained from the late Mr. Amram (Ron) Kodish, who collected seeds from various private gardens in Southern California which bore fruits of reasonable qualities. The initial success of this species led us to initiate an intensive research study, and today it is already fruit-crop, marketed mainly in Israel under the name " Koubo" . This paper will describe our work of domestication of this new cactus...

Use of cacti as heat sources by thermoregulating Mabuya agilis (Raddi) and Mabuya macrorhyncha Hoge (Lacertflia, Scincidae) in two restinga habitats in southeastern Brazil Zoologia
Vrcibradic,Davor; Rocha,Carlos Frederico Duarte.
Lizards may benefit from gain of heat from contact with the substrate via conduction. In this study, evidence that the lizards Mabuya agilis (Raddi, 1823) and Mabuya macrorhynclui Hoge, 1946 (Scincidae) inhabiting two restinga habitats in southeastern Brazil (Grussaf, Rio de Janeiro and Praia das Neves, Espfrito Santo), may shift microhabitat preferences along the day, and that such shifts may be related to the use of cacti surfaces as direct sources of heat is presented. For both species, body temperature (Tb) was always significantly correlated (p < 0,05) with air temperature (Ta). Tb was significantly correlated (p < 0,0.5) with substrate temperature (Ts) for M. agilis collected on cacti, but not for specimens collected on the ground. For M....
