1978～1979年冬季县柑桔品种鉴评时,在南靖县林场半山工区发现无核芦柑101株。无核芦柑形态特征与一般芦柑有差别,树势强健、直立,叶大浓绿,枝梢节间距离较长, 一年开花结果二次(卽春秋二花),冬季采收春花结的果,夏季采收上一年秋花结的果。果形端正略高,果皮薄,外表放射线明显,果心小。正造果可溶性固形物11.1％,维生素丙32.81毫克/百克果汁,柠檬酸0.477％,酸甜适口,品质佳,耐貯藏,其缺点是产量低。为了解无核芦柑的特性,在县果树站的协助下,我们对1978年选择的无核优良单株进行物候期及开花结果习性的初步观察与试验。因为它的发梢时间与一般芦柑人体相同,沒有记载,现仅将开花结果习性观察与试验结果简述如下:
During the appraisal of winter citrus varieties from 1978 to 1979, 101 seedless citrus trees were found in the Mid-mountain area of Forest Farm, Nanjing County. There is a difference between the morphological characteristics of non-nuclear citrus and general citrus. The tree vigor is strong, the erection is strong, the leaf is dark green and the distance between the internodes is longer. The fruit of the harvest of autumn fruit in the previous harvest in summer. Fruit shape is slightly higher end, thin skin, the appearance of radiation was obvious, fruit heart. Is making soluble solids 11.1%, vitamin C 32.81 mg / 100 grams of fruit juice, citric acid 0.477%, sweet and sour taste, good quality, storage resistance, the disadvantage is the low yield. In order to understand the characteristics of non-nuclear citrus, with the help of the county fruit tree station, we conducted a preliminary observation and experiment on the phenology and flowering habits of seedless elite individuals selected in 1978. Because of its hair tip time and the general body of citrus the same, there is no record, now flowering results are only observed and test results summarized as follows:
