“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
“Ganhua 79- 9” is the navel orange pearl seedling of Washington, and observed and studied the growth habit of “Ganhua 79- 9”. The results showed that the main tree of “Ganhua 79- 9” The results of the mother, accounting for 70.9% of the total number of fruit branches, followed by the results of spring and summer shoots mother; the variety of fruit rate was 1.36%, 14-year-old tree average yield of 6 3kg, equivalent to 31,185 kg ha. The “Ganhua 79- 9” has strong ecological adaptability, especially its cold resistance is stronger than that of Wenzhou mandarin and citrus. Under the condition of no cold prevention facilities, it can withstand low-temperature frost damage of 14.6 ℃ and quickly recover after freezing. “Ganhua 79- 9” male infertility, pollen sac empty, do not produce pollen or form a little transparent granule, the germination rate is zero. “Ganhua 79- 9” strong ability of parthenocarpic, pollinated whether or not the formation of non-nuclear fruit
