1. Biology, Flowering and Fruiting of the Cactus Opuntia spp.: A Review and Some Observations on Three Varieties in Morocco
ABSTRACT The cactus is a succulent plant resistant to droughts. According to the recently reviewed classification, cacti belong to the family of Opuntiaceae Desv. (synon. Cactaceae Juss.) with Opuntia Mill. as the typical genus. This genus is economically the most important in the family, as it includes a group of cactus pear plants which play an important r

2. Comparative HPTLC analysis of bioactive marker barbaloin from in vitro and naturally grown Aloe vera
ABSTRACT Aloe vera (L.) Burm. f., Xanthorrhoeaceae, a succulent, produces barbaloin, a bioactive compounds used in various pharmaceutical products. Extracts prepared from the leaves have been widely used as bittering agents, taste modifiers and also as cathartic agent against severe constipation. Barbaloin is reported for its anti-inflammatory, anticancer, a

3. Life history and larval morphology of Eurhinus magnificus Gyllenhal (Coleoptera: Curculionidae), a new weevil to the United States
Eurhinus magnificus Gyllenhal has been collected in south Florida, presumably introduced through trade with countries in its native range. Very little information has been published on the biology or taxonomy of this insect. We conducted studies to investigate various aspects of its life history and host plant associations. The pre-imaginal life stages of E.

4. Desenvolvimento de Kalanchoe Luciae cultivado em diferentes substratos e condiÃÃes de sombreamento / The development of Kalanchoe Luciae growing in different substrate and shading conditions
As suculentas sÃo plantas que apresentam grande importÃncia comercial, entretanto, em detrimento da grande diversidade de espÃcies, ainda pouco se conhece sobre as condiÃÃes de cultivo necessÃrias para cada uma delas. Dessa forma, objetivou-se, neste trabalho, avaliar o desenvolvimento de Kalanchoe luciae cultivado em diferentes substratos, adubaÃÃes

5. Occurrence of Pyruvate Orthophosphate Dikinase in the Succulent Plant, Kalanchoë daigremontiana Hamet. et. Perr. 1
Pyruvate orthophosphate dikinase was detected from Kalanchoë daigremontiana Hamet. et. Perr., a succulent plant with crassulacean acid metabolism. Enzyme activity was similar to that of maize extracts. Two enzymes demonstrating pyruvate orthophosphate dikinase activity from K. daigremontiana and Zea mays were found to be partially identical from enzyme-inhi

6. Suaeda monoica, a C4 Plant without Typical Bundle Sheaths
Suaeda monoica Forssk. ex J. F. Gmel was found to possess the C4 pathway of photosynthesis. The succulent leaves of Suaeda lack a green bundle sheath formation but have a layer of chlorenchyma, containing large and centripetally arranged chloroplasts, which surrounds the water tissue. We suggest that the proximity of a chlorenchymatous cell layer to the vasc

7. Salt Requirement for Crassulacean Acid Metabolism in the Annual Succulent, Mesembryanthemum crystallinum1
In experiments with the facultative Crassulacean acid metabolism (CAM) species, Mesembryanthemum crystallinum, only plants which received high levels of inorganic salts fixed substantial amounts of CO2 by the CAM pathway. Equivalent osmolarities of polyethylene glycol 6000 did not yield any CAM fixation. Plant water potential and turgor pressure had no detec

8. Epidermis-specific gene expression in Pachyphytum.
Transcripts of exclusively epidermis-specific expression were obtained by differential screening of a cDNA library prepared from isolated epidermis tissue of a succulent plant, Pachyphytum. Six transcripts were selected and characterized by RNA gel blot hybridization. Five cDNAs represented abundant mRNAs found exclusively in the epidermis. In situ hybridiza

9. Thermal Energy Exchange Model and Water Loss of a Barrel Cactus, Ferocactus acanthodes1
The influences of various diurnal stomatal opening patterns, spines, and ribs on the stem surface temperature and water economy of a CAM succulent, the barrel cactus Ferocactus acanthodes, were examined using an energy budget model. To incorporate energy exchanges by shortwave and longwave irradiation, latent heat, conduction, and convection as well as the h

10. Histochemical Compartmentation of Photosynthesis in the Crassulacean Acid Metabolism Plant Crassula falcata1
The succulent leaf of the obligate Crassulacean acid metabolism plant Crassula falcata comprises two distinct types of parenchyma. The peripheral tissue is dark green, whereas the central tissue is relatively colorless. We have investigated whether the conventional interpretation of Crassulacean acid metabolism—simply, temporal separation of light and dark

11. Environmental Influences on Open Stomates of a Crassulacean Acid Metabolism Plant, Agave deserti1
The major short term stomatal response of Agave deserti was to temperature; increases in leaf temperature led to decreases in water vapor conductance for stomatal opening during the daytime (C3 mode) as well as at night (Crassulacean acid metabolism or CAM mode). Hourly changes in the water vapor concentration drop from leaf to air had no significant stomata

12. Photomodulation of Axis Extension in Sparse Canopies 1: Role of the Stem in the Perception of Light-Quality Signals of Stand Density
A fiber optic probe inserted into plant tissues was used to investigate the effects of canopy density on the light environment in different organs. The red:far-red ratio inside the stem of Datura ferox L. seedlings and the estimated phytochrome photoequilibrium were strongly reduced by the presence of neighbors forming canopies too sparse to cause any mutual
