The main problem being http://davesgarden.com/guides/pf/go/56543/ they are monocarpic. Once they flower, they croak, and then there is a monstrous dead tree to remove from your backyard, or wherever it is. And it's not a simple tree to remove. Caryotas are famous for having some of the hardest wood in the plant kingdom. Chainsaws will barely cut into one alive, and they seem to get harder once they die. On top of that, Caryotas have wimpy root systems. I guess where they're from (the Asian tropics usually) there is little wind and no need for large root systems. Anyway, a good Santa Ana wind will easily knock one of these trees over, and they can weigh several tons.

  • Genetic Variation and Agronomic Features of Metroxylon Palms in Asia and Pacific
    Chapter 4 Genetic Variation and Agronomic Features of Metroxylon Palms in Asia and Pacific Hiroshi Ehara Abstract Fourteen genera among three subfamilies in the Arecaceae family are known to produce starch in the trunk. The genus Metroxylon is the most productive among them and is classified into section Metroxylon including only one species, M. sagu (sago palm: called the true sago palm), distributed in Southeast Asia and Melanesia and section Coelococcus consisting of M. amicarum in Micronesia, M. salomonense and M. vitiense in Melanesia, M. warburgii in Melanesia and Polynesia, and M. paulcoxii in Polynesia. In sago palm, a relationship between the genetic distance and geographical distribution of populations was found as the result of a random amplified polymorphic DNA analysis. A smaller genetic variation of sago palm in the western part than in the eastern part of the Malay Archipelago was also found, which indicated that the more genetically varied populations are distributed in the eastern area and are possibly divided into four broad groups. Metroxylon warburgii has a smaller trunk than sago palm, but the trunk length of M. salomonense, M. vitiense, and M. amicarum is comparable to or longer than that of sago palm. Their leaves are important as building and houseware material, and the hard endosperm of M. amicarum and M. warburgii seeds is utilized as craftwork material. Preemergent young leaves around the growing point of M. vitiense are utilized as a vegetable. Regarding starch yield, palms in Coelococcus are all low in the dry matter and pith starch content as compared with sago palm. For this reason, M.

The mature larva and pupa of each species are illustrated. We also provide a compilation of host records for members of the Brassolinae and briefly address the interaction between these butterflies and their larval food plants, Additional key words: Central America, host records, monocotyledonous plants, larval food plants. The nymphalid subfamily Brassolinae includes METHODS Neotropical species of large body size and crepuscular habits, both as caterpillars and adults (Harrison 1963, Between 25 May and .31 December, 1994 we Casagrande 1979, DeVries 1987, Slygley 1994). Larvae searched for ovipositing female butterflies along generally consume large quantities of plant material to Pipeline Road, Soberania National Park, Panama, mo­ reach maturity, a behavior that may be related as much tivated by a study on Caligo mating behavior (Srygley to the low nutrient content of their larval food plants & Penz 1999).

GUNAWARDENA and M.N.A. SWARNAKANTHI Department of Chemistry, University of Kelaniya, Kelaniya. (Received: 20 November 1992; accepted: 3 January 1995) Abstract: Steam bark distillates of the typica and aurancica varieties of Cocos nucifera (host plant) Ternlinulia catappa (Kottamba) and Albizzia urnara Boiv. (Albizzia) (nonhost plants) and Areca catechu L. (Puwak) and Areca concmna Thw. Enum. (Lentheti)(alternate hosts) were subjected to electrophysiological and behavioural assays to compare the attractiveness to the coconut pest, Rhynchophorus ferrugineus F. (Coleoptera: Curculionidae). In the electroantennogram (EAG) assay, the steam distillates of C. nucifera form aurancica elicited the highest response of 79.1% (relative to standard) and the form typica (young bark) 55.6% to the antenna ofR. ferrugineus both values being significantly different (p<0.05, ANOVA, Scheffe's test) from those of the nonhosts T. catappa and A. amara (10.9% and 5.9% respectively). EAGs of old bark (51.4%) steam distillate of C. nucifera form typica did not differ signifi- cantly from that of the young bark distillates (55.6%). The two alternate hosts, A. catechu and A. concinna showed moderate EAG activities (29.4% and 25.9% respectively) between those of host varieties and nonhosts. In a behavioural assay (choice test) using an olfactometer the steam distillates of host palms were more attractive (pc0.05, ANOVA, Scheffe's test) to the red weevil than those of the nonhosts.

ISSN 2349-7750 CODEN (USA): IAJPBB ISSN: 2349-7750 INDO AMERICAN JOURNAL OF PHARMACEUTICAL SCIENCES Available online at: http://www.iajps.com Research Article IN VITRO ESTIMATION OF ANTIOXIDANT ACTIVITY OF CARYOTA URENS FRUITS Md. Sahab Uddin*, Md. Fakhrul Hasan, Abdullah Al Mamun, Md. Sarwar Hossain, Md. Tanjir Islam, Md. Asaduzzaman Department of Pharmacy, Southeast University, Dhaka-1213, Bangladesh Abstract: Background: Complementary and alternative medicine based on plants is the world's oldest form of medicine and recent reports suggest that such therapies still enjoy vast popularity, especially in developing countries where most of the population does not have easy access to modern medicine. Aim: The objective of this study was to evaluate the antioxidant activity of chloroform fraction (CLF), carbon tetra chloride fraction (CTF) and n-Hexane fraction (NHF) of methanolic extracts of Caryota urens (CU) fruits. Method: For determination of antioxidant property of the CU fruits extracts, DPPH (2,2‐diphenyl‐2‐picrylhydrazyl) radical scavenging assay was performed. Results: Among three different fractions CLF showed the highest antioxidant activity (61.58 % scavenging) at 400 µg/ml concentration followed by CTF and NHF. The IC50 values for the DPPH radical scavenging test were in the order of CLF (93.45 ± 3.09 µg/ml) > CTF (473.01 ± 12.95) > NHF (613.13 ± 7.64). Conclusion: Our study suggested that CLF of CU fruits had strong antioxidant effect compared to CTF and NHF. Keywords: Complementary and alternative medicine, Caryota urens, Antioxidant activity, DPPH radical scavenging assay. *Corresponding author: Md.

  • Effects of Plant Size on Reproductive Output and Offspring Performance In
    Journal of Blackwell Science, Ltd Ecology 2002 Effects of plant size on reproductive output and offspring 90, 958–966 performance in the facultative biennial Digitalis purpurea NINA SLETVOLD Department of Biology, Division of Botany and Plant Physiology, University of Oslo, PO Box 1045 Blindern, N-0316 Oslo, Norway Summary 1 Monocarpy in facultative biennials can be favoured by selection when there is a more than proportional increase in fitness with size. The possible contributions of larger reproductive output and higher offspring quality to such an increase were investigated in the facultative biennial plant Digitalis purpurea. Straw mass (rosette leaves and flower- ing stem excluding fruits and seeds) was determined for 100 individuals of varying size and correlated with the number of flowers and seeds per flower to examine whether sex- allocation is size dependent. 2 To determine whether maternal size influences offspring growth, and whether this effect is more pronounced in the presence of competition, seeds from 32 maternal plants were grown alone, and with one, two or four competitors. 3 Total seed number increased proportionally with size. Seed quality, measured as seed size, germination percentage and speed also increased with maternal size. The combined fitness measures of total seed mass (seed number × seed size), number of seedlings (seed number × germination percentage) and total female fitness (seed number × germination percentage × mean offspring dry mass after 14 weeks) all increased disproportionally with size. 4 Sex-allocation was size dependent, with large plants emphasizing the female function. 5 Offspring dry mass after both 8 and 14 weeks of growth was strongly influenced by competition, whereas the effect of maternal size was significant only at the first harvest date.

A comprehensive taxonomic review of the genus and species was carried out by Mesa et al. (2009), which lists all suspected junior synonyms of R. indica, including Raoiella camur (Chaudhri and Akbar), Raoiella empedos (Chaudhri and Akbar), Raoiella obelias (Hasan and Akbar), Raoiella pandanae (Mohanasundaram), Raoiella phoenica (Meyer) and Raoiella rahii (Akbar and Chaudhri). The review also highlighted synonymy with Rarosiella cocosae found on coconut in the Philippines.
