摘  要：
“赣华 79- 9”是华盛顿脐橙珠心苗 ,对“赣华 79- 9”的生长结果习性进行观察研究 ,结果表明 :“赣华79- 9”成年树以春梢结果母枝为主要结果母枝 ,占结果母枝总数的 70 .9% ,其次为春夏梢结果母枝 ;该品种的座果率为 1.36 % ,14年生树平均单株产量为 6 3kg ,折合公顷产 31185kg。“赣华 79- 9”的生态适应性强 ,特别是其抗寒能力比温州蜜柑、柑强 ,在无任何防寒设施条件下 ,能抵御 - 14.6℃的低温冻害 ,且冻后恢复快。“赣华 79- 9”雄性高度不育 ,花粉囊空囊 ,不产生花粉或形成少许透明的空粒花粉粒 ,发芽率为零。“赣华 79- 9”单性结实能力较强 ,不论授粉与否均形成无核果实

摘  要：
Ganhua 79-9” is the nucellus embryo of Washington naval orange. The observation and study on its growth and fruit setting habits show that: its spring shoot is the first main fruiting cane, 70.9% of which can bear fruit, and the spring summer shoot is the second. Its percentage of fruit-bearing is 1.36%, and the average output of a 14-year old fruit-setting tree is 63kg, which is equal to 31185kg per hectare. “Ganhua 79-9” has strong ecological adaptability. Moreover, its cold-resistance is better than that of Wenzhou Mandarin, Orange and Ponggan, for example, without any coldproof facilities, it can resist the freeze injury of low temperature of -14.6℃, and if freezed, it recovers quickly. The male of “Ganhua 79-9” has no fertility and empty pollen sac, which can produce no pollen grain; or only a few from some transparent empty pollen grains, so its germination percentage is zero. The parthenocarpy ability of “Ganhua 79-9” is stronger, whether it is pollinated or not, seedless fruit can be born.
