038-Lancaster Farming Saturday, April 6,1985 Harsh Winter hurts plants CREAMERY - Winter weather conditions in mid February have threatened plant quality and survival, according to County Agent Paul Reber. Gardeners are concerned about winter’s influence on spring flowering and the quality of the total plant. It is still too soon to see the results of this year’s sub-zero temperatures. Weather-related plant problems are compounded when low temperatures are ac companied by severe winds. Under these conditions, frozen plant tissue is capable of losing water that can’t be replaced by water from the frozen soil. This is similar to what occurs when washed clothes are hung out to dry on a winter day. The wet clothes quickly freeze, but water molecules are continually being blown from the cloth. When all the water has been blown away, the clothes are dry. Reber indicated the chemical nature of water in plant tissues, as well as the physical qualities of plant tissues themselves, retards the drying process. Even with the safeguards of nature, however, water is lost. When a critical amount of water is lost, tissue injury and/or death can occur. The best protection against wind-induced injury is a reduction in the total amount of air moving past the plant. Fortunately, not all plants are equally susceptable to wind injury, so durable species can be used to protect less durable ones. This is essentially the con cept of windbreaks. Observing wind patterns on your property will help in identifying sites that are more severe for plants than others. Generally, narrow areas between structures and bed areas that extend outward from an exposed corner receive the greatest air movement.

The construction of artificial barriers may be another wind control solution. Screens and fences won’t stop the wind, but they help slow it down or channel it away from plants, walkways and houses. Remember, screens may function as snow fences. Place them so snow won’t accumulate on walkways or driveways. The warm weather we had earlier this winter will also in fluence spring plant quality. Temperatures in the 50’s and 60’s tend to keep flower buds more active and less dormant. A number of plants were in bloom earlier this winter, which suggests a reduction in spring flowers. The sudden cold weather may cause considerable injury to partially open flower or leaf buds and stem tissues. Injury won’t be evident until growing conditions return in spring. In addition to injury caused by drastic temperatures changes, specific plants are injured by minimum low temperatures. Every plant species has a minimum tolerance level. When temperatures drop below that point, injury can occur. This plant quality is called hardiness. Research indicates that roots are often less tolerant of low temperatures than top growth. When a plant leafs out in the spring and then quickly dies in a few weeks, it’s possible that its roots were killed by low temperatures during the previous winter. Enough moisture reserved in the stem may support bud and leaf formation, but a dead root system is unable to sustain water supply to the new leaves. Researchers also found that root injury may occur at temperatures 10 to 15 degrees warmer than those needed to in jure stem and bud tissues. 61 ‘New biology" (Continued from Page D 37) ficiency and productivity to new heights. In the areas of the plant scien ces, the report calls for stepped-up research to make crop plants more efficient producers of food through intensified studies of photosyn thesis, biological nitrogen fixation, regulation of plant growth and development, gene expression, cell culture and plant regeneration, plant response to stress factors such as drought, salt, cold, heat, and toxic chemicals in soil, among other things. The average yield for eight major U.S. crops - corn, wheat, soybeans, sorghums, oats, barley, potatoes, and sugar beets - is estimated to be only some 20 percent of the record yield for the sar ° crops, the report points out.

As for animal production, the report suggests research to be strengthened to overcome numerous barriers to greater production efficiency. Among areas of research that should receive greater attention, as the report points out, are molecular basis of disease and metabolic regulation with focus on genes regulating the immune response, pathogens and disease carriers, characterization of hormones and other bodily chemicals, and metabolic control and functioning of cells. Studies dealing with test-tube manipulation of cells and embryos, Improved Udder Health "NuPulse has helped improve our average from 16,000 lbs. to 21,500 lbs. at 3.6 test in a home bred herd. We've never lost any cows due to mastitis. Our top producer has 29,413 lbs. milk, 992 lbs. fat in 365 days. Our udder health is 95% better with NuPulse than ever before. The NuPulse is simple to maintain with no problems." Less Cup Fall-Off and Less Mastitis 'We replaced our old milker with NuPulse MLX. We're not having any fall off problems now. The MLX milks our cows out clean without machine stripping. Udders are more even now. We have not had to buy mastitis medication except to dry treat. We are very happy with NuPulse." Faster Milking 'We replaced DV3oo's with NuPulse. I have not had any fall off since. Our cows accepted NuPulse easily. Milking alone I get 1,000 lbs. per hour with 4 units " Ease of Maintenance "Our cows udder health is the best ever. The only mastitis we have is when a cow gets injured. We do our own maintenance. We have been very pleased with NuPulse." “You can spend more money, but you can’t get a better milker. ” W America, Inc. 908 Stewart Street.

In addition to identifying priority research areas, the report spells out some of the conditions that can provide the optimum research environment in meeting the challenge ahead. These conditions include the availability of funds, quality researchers, suitable facilities, the equipment, and “the presence of an attitude that en courages and supports scientific research of the highest caliber.” “The outcome of the best science is unpredictable, but scientific research at times yields a unifying idea or theory - a key that revolutionizes the understanding of a specific area of science and opens the way to new discoveries and practical applications,” the reports state. “This has just happened in biology with molecular genetics.” rg »r *wo »t^' • BAGS OR BULK SERVICE FARMERS FERTILIZER WORKS, INC. 365 W.
