An initial population of PHU-STN hybrid diploid potatoes was screened in 1978 at the Mountain Horticultural Crops Research Station, Fletcher, N.C. for high specific gravity and tuber production. Sixty clones were selected for testing under high temperatures at two North Carolina coastal locations. Twenty-seven clones maintained a relatively high specific gravity and acceptable tuber production under these high temperatures. The other 33 either were low in specific gravity or produced few, if any, tubers. Specific gravity was lower at the two coastal locations than at the Mountain Horticultural Crops Research Station. The 27 relatively stable, high specific gravity clones were retested in 1980 along with seven additional clones included for the first time. Severe high temperatures resulted in low survival rates and low specific gravity. However, eight clones maintained a relatively high specific gravity in relation to the rest of the population. 相似文献

High performance fibers have distinguished properties such as high tensile strength, good thermal and chemical resistance, dimensional stability, lightweight, and high electrical conductivity. Due to these superior properties, high performance fibers made it to the scene of broad range of applications such as aerospace, automotive, windmill, fiber reinforced composites, high strength tethers, tendons for scientific balloon, tension structures, protective clothing, and marine. Examples of such fibers are Zylon®, Kevlar®, and Vectran®. However, the fibers lose their strength significantly upon exposure to Ultraviolet (UV) and visible light. In this research, UV protective films from extruded low density polyethylene (LDPE) loaded with different content of UV stabilizers (TiO2 nanoparticles and White PE CC®) were investigated. To assess the degree of UV blockage of each extruded protective film, their transmittance to UV and visible (UV-VIS) light was measured. Additionally, Zylon® braids were sheathed with the protective films and the strength of the braids and yarns raveled from braids was measured before and after UV exposure for different number of days. LDPE loaded with White PE CC® and 10 % TiO2 showed the least transmittance to UV-VIS and their yarns and braids exhibited highest strength retention after exposure to artificial UV. Strength retention of braids was higher than that of individual yarns due to weak link effect and braid structure assistant. 相似文献
