| 圣华玉12 号是以自交系粤农9 号选-5 为母本、自交系B73-1 为父本杂交育成的高产优质早熟玉米新品种。经2013 年—2014 年广东省春植普通玉米区域试验、生产试验和试验示范，结果显示，两年区域试验平均产量5 157.0 kg/hm2，比对照种华玉8 号增产8.9%；生产试验平均产量6 787.5 kg/hm2，比对照种华玉8 号增产14.29%；淀粉含量为64.6%，蛋白质含量为9.72%，脂肪含量为3.30%，容重为791.94 g/L，品质优良；耐贫瘠，适宜在广东春秋季节种植，具有较大的推广价值；2015 年通过广东省农作物品种审定。 |
| 英文摘要: |
| In order to study the influences of different stocks（3309-144，3309-173，SO4-20，1103P-768，1103P-VCR107，1103P-VCR 119 and 1103P-CFC60-30） on Cabernet Sauvignon， the grape growth，photosynthetic parameters and chlorophyll content were detected. The results showed that stock had significant influences on the growth，photosynthetic parameters and chlorophyll content of Cabernet Sauvignon. The net photosynthetic rate（Pn），stomatal conductance（ Gs） and instantaneous carboxylation efficiency（ Pn/Ci） of Cabernet Sauvignon/1103P-VCR119 were higher than those of others，while the intercellular concentration of carbon dioxide（ Ci） was
lower，so photosynthesis productivity of the variety behaved better，its growth and chlorophyll content were higher than those of others. Thus，1103P-VCR119 was the most suitable stock for Cabernet Sauvignon in the area of drought and soil salinization. |
