Buffers vegetative

Fruit and vegetable juices packed with 21-26 in. of vacuum and stored in uncoated aluminum cans caused severe corrosion as shown in Table III. The corrosion rate brought about by the juices depends more on the nature of the organic acid present and the buffering capacity of the juice than on the total titratable acidity (11). The use of coated aluminum containers considerably minimized corrosion problems. Product control under extended storage conditions may be achieved by using specific chemical additives. However, more work is needed in this area before final conclusions can be reached. 

As tree fruit species are perennial crops, year-to-year influences are often detected. For example, factors in the previous year(s) (e.g. water or nutrient deficiency, hail storm damage, shoot deformation caused by aphids, too high or too low crop load) strongly influence the tree s performance in the next year (Tromp and Wertheim, 2005). Thus, a major objective of agronomic practices used is to buffer the orchard from stress and to keep trees in a balance/equilibrium between vegetative and generative activity. 

Antioxidants in fruits and vegetables including vitamin C and (3-carotene reduce oxidative stress on bone mineral density, in addition to the potential role of some nutrients such as vitamin C and vitamin K that can promote bone cell and structural formation (Lanham-New 2006). Many fruits and vegetables are rich in potassium citrate and generate basic metabolites to help buffer acids and thereby may offset the need for bone dissolution and potentially preserve bone. Potassium intake was significantly and linearly associated with markers of bone turnover and femoral bone mineral density (Macdonald and others 2005).

IEC was applied to determine biogenic polyamines such as putrescine (4a), cadaverine (4b), tyramine (5), histamine (6), spermidine (38), agmatine (39) and tryptamine (40), contained in aqueous trichloroacetic extracts of leafy vegetables, such as cabbage and lettuce. A cation exchange column loaded with potassium ions and a special buffer were used. Spermidine (38) was the major amine detected in this group (7-15 Xg/g fresh weight)144.

Farmers are environmental stewards and are applying many BMPs to reduce erosion and improve water quality. BMPs can be structural (e.g., a mixing-loading pad) or nonstructural (e.g., a tillage practice, vegetative buffer strip, or other agricultural practices). As the adoption of BMPs increases, levels of pesticides, nutrients, and sediment in water will continue to decline.
