Experiments on the Digestibility of Prickly Pear by Cattle

Many chemical analyses have been made of a number of different members of the cactus family to determine their value as a feeding stuff for animals.? With this data we are enabled to judge with a fair degree of accuracy the amount of the various nutrients contained by many different species of this group of plants, as well as by different parts of the same plant. However, as no record of digestion experiments with any of the cacti has been found, it was impossible to say what proportion of the different nutrients were available to the animals.

Photosynthesis and Photorespiration in Typha latifolia

Photosynthetic rates of Typha latifolia, the broad-leaved cattail, are the equivalent of rates reported in tropical grasses and other plants which assimilate carbon by the phosphopyruvate carboxylase reaction, but photosynthesis in T. latifolia proceeds by a typical Calvin cycle. Glycolate oxidase, the photorespiratory enzyme, is present in high concentration in this species, but only minor quantities of the assimilated carbon pass through the photorespiratory pathway. However, continued operation of the pathway is apparently essential in the maintenance of assimlilatory capacity.

ECONOMICALLY AND CULTURALLY IMPORTANT USAGE POTENTIAL OF CHICORY (Cichorium intybus L.)

Cichorium intybus L., commonly known as cichory in English and white chicory in Turkish, is an important medicinal plant. It belongs to the Asteraceae family. The most used parts of this plant are its aerial parts, flowers, seeds and roots. All parts of this plant are rich in essential oil, fatty acids, unsaturated sterols, alkaloids, triterpenes, vitamins, flavonoids, tannins, coumarins, saponins, terpenoids, cardiac glycosides, sesquiterpenes, lactones, anthocyanins and phenols.

Cichorium intybus: Traditional Uses, Phytochemistry, Pharmacology, and Toxicology

Medicinal plants have been used for centuries and numerous cultures still rely on indigenous medicinal plants to meet their primary health care needs. It is likely that the insightful knowledge of plant-based remedies in traditional cultures advanced through trial and error and that the most important cures were carefully passed from one generation to another. Historically, chicory was grown by the ancient Egyptians as a medicinal plant and it has had a long history of therapeutic use both in areas where it is indigenous and in areas where it has been introduced.

Kasni (Cichorium intybus): A Unani Hepatoprotective Drug

Kasni (Cichorium intybus Linn.) is a powerful hepatoprotective and nephroprotective drug which has been extensively used in Unani System of Medicine. It is commonly known as chicory in English language. It is an erect perennial herb of the dandelion family Asteraceae. There are two types of Kasni depending on colour of the flowers which are usually bright blue and white or pink rarely. Chicory consists of a dietary fibr e called as Inulin which is very useful in treating diabetes and constipation.

Multiple Approaches To The Restoration Of Disturbed Desert Land

Three experiments were conducted to examine restoration of disturbed land in Arizona. The first experiment attempted to revegetate abandoned farmland by direct seeding native seeds and using various soil preparation techniques, amendments, and weeding of Salsola iberica. Only irrigation and weeding had a significant effect on seed germination and canopy cover. Irrigation increased plant cover on plots, but weeds dominated the cover. A seedbank study conducted near the end of the second growing season found the soil was dominated by weeds and contained few viable native seeds.

Rainfall regimes of the Green Sahara

During the early Holocene epoch [11,000 to 5000 years before the present (yr B.P.)], the hyperarid Sahara was transformed into a mesic landscape, with widespread grasslands, variable tree cover, large per- manent lakes, and extensive river drainage networks. Evidence for this “Green Sahara” interval comes from paleolake deposits, pollen, and archaeological remains, indicating that humans inhabited, hunted, and gathered deep within the present-day desert (1–3).

High concentrations of biological aerosol particles and ice nuclei during and after rain

Bioaerosols are relevant for public health and may play an important role in the climate system, but their atmospheric abundance, properties, and sources are not well understood. Here we show that the concentration of air- borne biological particles in a North American forest ecosystem increases significantly during rain and that bioparticles are closely correlated with atmospheric ice nuclei (IN). The greatest increase of bioparticles and IN occurred in the size range of 2–6 μm, which is characteristic for bacterial aggregates and fungal spores.

Effect of Volumetric Water Content and Clover (Trifolium incarnatum) on the Survival of Escherichia coli

Studies aimed at understanding Escherichia coli O157:H7 soil survival dynamics are paramount due to their inevitable introduction into the organic vegetable production systems via animal manure-based fertilizer. Therefore, a greenhouse study was conducted to determine the survival of E. coli O157:H7 in highly controlled soil matrices subjected to two variable environmental stressors: (1) soil volumetric water content (25 or 45 % VWC), and (2) the growth of clover (planted or unplanted). During the 7-week study, molecular-based qPCR analyses revealed that E.
