优质早籼『湘早籼31号』的选育及应用 总被引:2,自引:0,他引:2
培育优质早籼品种 ,改善早籼品质 ,是解决南方劣质早籼严重压库与销售不畅局面的根本出路。围绕这一目标 ,我们育成了米质优、丰产性好、适应性强、熟期适中的早籼新品种湘早籼31号 (原名丰优早11号 ) ,并于2000年2月通过湖南省农作物品种审定委员会审定。这也是我省继湘早籼15号 (湖南软米 )之后 ,培育的通过省级审定的又一优质早籼新品种 ,目前正在全省大面积推广应用。一、选育经过1990年我们从省内外引进的40多份优质源材料中 ,筛选出了米质优、丰产性较强的舟903作为骨干亲本 ,于1991年与我省早稻材料配制了大… 相似文献

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
