formation of carbon monoxide during seed germination and seedling growth.carbon monoxide was formed during the growth of cucumber seedlings in the dark in atmospheres containing 5 percent oxygen or less, but not by aerobic seedlings. the highest level recorded was 6000 ppm. carbon monoxide was also formed by euphorbia. germinating seeds of rye, cucumber, and other species also produced carbon monoxide at levels of 10 to 25 ppm.196217770955

mitotic waves in laticifers of euphorbia marginata.a successive pattern of nuclear divisions that result in mitotic waves has been observed within the coenocytic nonarticulated laticifers of embryos of euphorbia marginata pursh. these waves originate independently in the cotyledonary or hypocotyl portion of the laticifer and exhibit uni-or bidirectional movement at variable velocities. individual nuclei or groups of neighoring nuclei in a laticifer were observed in a sequence of mitotic stages ranging from prophase to telophase; division activit ...196617815080

carbon dioxide compensation points in related plant species.both high and low c0(2) compensation concentrations were found in the plant genera-panicum, cyperus, and euphorbia. within each genus, however, high and low compensations were found in different subgenera. thus, they may not be genetically closely related. no significant differences in co(2) compensation were found among 100 genetic lines of triticum aestivum l. or among 20 lines of hordeum vulgare l.19695774193

phorbic acid biosynthesis in the latex vessel system of euphorbia.evidence is presented that phorbic acid is formed in the latex producing cell system, rather than in photosynthetic or chlorophyll-free tissues of euphorbia resinifera berg. when a branch of the plant was kept first in a (14)co(2) atmosphere with 12 hr light-dark periods for 2 days and then left under natural conditions in the air outside for at least 2 to 3 days, radioactive phorbic acid was found in the latex. phorbic acid synthesis appeared to be independent of the photosynthetic and respirat ...196916657036
inhibition of nitrogen-fixing and nitrifying bacteria by seed plants: vi. inhibitors from euphorbia supina.euphorbia suinna occurs in the pioneer weed stage of succession in abandoned fields in several midwestern states of the united states. it was previously found to be very inhibitory to several test strains of nitrogen-fixing and nitrifying bacteria and to several associated seed plants. the present project was concerned wilh the identification of the chief inhibitors produced by that species, using appropriate column and paper chromatographic techniques, and by tests of bacterial inhibition emplo ...196920925667

ecological aspects of the jos plateau, nigeria.the jos plateau has an area of about 6 700 km(2), lies at 1 280 m above sea level, and contains approximately 1 million inhabitants. annual rainfall averaged 137 cm in the period 1965-68; in 1969 rainfall totalled 170 cm and lasted for a month longer than usual.the rural population is engaged in agriculture, tin mining, and cattle grazing. animal life consists chiefly of domestic species; there are few large wild animals. wild primates are apparently rare, although baboons and red patas monkeys ...19724538036

an excellent source of vegetative buds for use in plant hormone studies on apical dominance.when studying the role of plant hormones in the control of growth at apical meristems, it is often difficult to obtain needed amounts of physiologically uniform buds. a source and method are described for obtaining sufficient quantities of large, uniform buds and for the treatment of the buds with indoleacetic acid and kinetin. buds from the root system of euphorbia esula l. were grown in petri plates, with agar suspending the short root sections from which they emanate. plant hormones are appli ...197316658506

on the active principles of the spurge family. iii. skin irritant and cocarcinogenic factors from the caper spurge.the toxic and irritant principles of the seed oil and of the latex of the caper spurge (euphorbia lathyris l.) were isolated together with several non irritants of similar chemical structure. from the seed oil two irritant euphorbia factors l5 and l6 and from the latex a mixture of irritant euphorbia factors were obtained. euphorbia factor l5 was identified as 3-hexadecanoate of the new tetracyclic, poly-functional diterpene parent alcohol ingenol. euphorbia factor l6 most probably is the 3-tetr ...1975128221

skin irritants of euphorbia means of a combination of partition and chromatographic methods six irritant constituents were isolated from the fresh latex of euphorbia fortissima. compounds a-d were di-esters of the common parent diterpene 12-deoxyphorbol, and compounds e and f were mono-esters of the same diterpene. the fresh latex had an irritant dose 50% (id50) on mice of 0-64 mug mul- minus 1. compounds a-d are short-acting irritants reaching a maximum activity within 4 h of application to the skin, whilst the monoest ...1975239133
spectrophotometric estimation of individual flavone glycosides in three euphorbia species.two spectrophotometric methods (conventional and differential) are carried out for the estimation of flavone glycosides (hyperoside and/or kaempferol-3-beta-glucoside) in euphorbia paralias l., and euphorbia helioscopia l. the glycosides are extracted with methanol from the aerial parts of the different euphorbia species, separated on silica gel chromatoplates, and eluted by refluxing with methanol (80%). the absorbance value (conventional method) and the delta absorbance value (differential met ...19751161795

c(4) photosynthesis in tree form euphorbia species from hawaiian rainforest sites.the (13)c (12)c isotope ratios and the leaf anatomy of 18 species and varieties of euphorbia native to the hawaian islands indicated that all possess c(4) photosynthesis. these species range from small prostrate coastal strand shrubs to shrubs and trees in rainforest and bog habitats. the results show that c(4) photosynthesis occurs in plants from a much wider range of habitats and life-forms than has been previously reported.197516659208

antileukemic principles isolated from euphorbiaceae plants.extracts of euphorbia esula l. and croton tiglium l., two members of the euphorbiaceae which have been used widely in folk medicine for treating cancers, showed antileukemic activity against the p-388 lymphocytic leukemia in mice. systematic fractionation of the extract of euphorbia esula l. led to characterization of a major antileukemic component as the new diterpenoid diester, ingenol 3,20-dibenzoate. similar fractionation of croton oil led to characterization of phorbol 12-tiglate 13-decanoa ...19761251193
[occupational allergy due to inhalation of pollen from euphorbia fulgens karw (author's transl)].the increased cultivation and sales of euphorbia fulgens karw., originating in mexico, has in the last few years led to occupational allergy, type i, in three growers manifesting itself as nasal disease, tracheobronchitis or bronchial asthma. intracutaneous tests with pollen extracts were positive in all cases, even at high dilution. a specific hyposensitisation regimen, conducted over five months, gave highly promising results in one patient who had no symptoms in the following season, despite ...19761261372
axenic cultivation of phytomonas davidi lafont (trypanosomatidae), a symbiote of laticiferous plants (euphorbiaceae).phytomonas davidi (trypanosomatidae) originally discovered by lafont in 1909 on the island of mauritius was rediscovered in euphorbia cyathophora in florida. successful cultures were established in diphasic medium consisting of duck blood agar and modified phillips' medium as overlay. optimal growth was obtained when mansour's medium was used as overlay and poorest growth when cowperthwaite's medium buffered at ph 5.0 was utilized for this purpose. marked changes tending toward choanomastigotes ...1976933080
