Heteromeles arbutifolia (from yellow fruit), "TOYON" Versatile, Calif. native, water-efficient small tree/large shrub w/ toothed, glossy green leaves, large clusters of white flowers in summer, showy red berries in winter; some may produce yellow berries. [9] (H*B*W*C*) Homalanthus populifolius, "QUEENSLAND POPLAR" Small, Aust. rainforest tree that is surprisingly hardy; fast-growing w/ handsom...

--After three growing seasons, green ash had produced 7,342 pounds per acre of above-ground dry matter compared to 3,572 for oak. Of the total biomass, ash had 53% in the bole (wood plus bark), 22% in old branches, 21% in leaves and 4% in new growth; oak had 50%, 21%, 24%, and 5% in the same components. These proportions changed after leaf fall. Concentrations of N, P, K, and Mg followed the ge...

Leaf senescence in field-grown soybean (Merrill) as defined by the period after full expansion, was studied by measuring abscisic acid (ABA), total soluble protein, and chlorophyll in leaves through the later part of the growing season. ABA concentrations increased significantly at the end of the season when leaves had started to turn yellow, well after total soluble protein and chlorophyll had...

Major differences stand out between edible leaves and seeds in protein quality, vitamin, and mineral concentrations and omega 6/omega 3 fatty acid ratios. Data for seeds (wheat, rice, corn, soy, lentil, chick pea) are compared with corresponding data for edible green leaves (kale, spinach, broccoli, duckweed). An x/y representation of data for lysine and methionine content highlights the group ...

The plant has tuberous roots, deep green leaves and a scarlet coloured fruit with a bitter taste. The Ayurvedic writers recommend the juice of its tuberous roots and leaves in diabetes; the leaves are also used by them in skin diseases. We investigated the anti-diabetic properties of this plant as its juice is often prescribed by medical practitioners in Bengal and wonderful results are ascribe...

Due to the massive loss of leaves in parks and green spaces and big cities such as Isfahan and the lack of domestic production of leaf vacuum shredder machine for use in large green spaces of parks, the design and construction of the collecting and recycling by the system is need so the design of the vaccum section which is one of the main parts and includes entrance, channels and ducts and exh...

Green tea polyphenols have been reported to possess many biological properties. Despite the many potential benefits of green tea extracts, their sensitivity to high temperature, pH and oxygen is a major disadvantage hindering their effective utilization in the food industry. Green tea leaves from the Cameron Highlands Malaysia were extracted using supercritical fluid extraction (SFE). To improv...

Accurate information on the organic acids of leaves is surprisingly meager; even the identity of the acidic substances in many of the plant tissues that have been investigated is still in doubt. Franzen and Keyssner (1) pointed out some years ago that the identity of the malic acid had been conclusively proved in only 15 of 235 plants reported in the literature to contain this substance and a s...

Successive leaf sections from the base to the tip of rapidly developing leaves of 7-day-old maize (Zea mays var. Kelvedon Glory), grown in the light, utilized acetate for fatty acid biosynthesis in a very divergent manner. Basal regions of the leaf containing proplastids synthesized insignificant proportions of unsaturated fatty acids and appreciable proportions of fatty acids with 20 or more c...
