在1958年果树资源调查中,在山西省灵丘县梨园村发现有一株17年生的穗状核桃。一般我们所发现的穗状核桃多是不定性的,只是在一棵植株上,偶而见有部分果枝着果变成了穗状;但在灵丘县所发现的这株穗状核桃,却与一般不同,果枝全为穗状果穗,且是定性的,每年所新生的果枝都是这样。新品种的形态大体上与绵核桃相似,其不同点是:新梢生长迅速,一般长24—48cm,最长的68cm。结果枝是扁圆形的,生长缓慢,一般长5—12cm,最长的16cm(如图1)。果实的特点是形小(横径2.6cm,纵径2.8cm。)平均个重5.8克,外壳多由3个缝合线组成。种皮薄,仁易取出,种仁白色,饱
In the 1958 Fruit Resources Survey, a 17-year-old spike walnut was found in Liyuan Village, Lingqiu County, Shanxi Province. In general, we found that the spiciness of walnuts is mostly indefinite, but only in a plant, and occasionally see some fruiting branches become spikes; but found in Lingqiu this spike walnut, but with In general, fruiting branches are all spike-like ear, and is qualitative, each year the new fruit branches are like this. The new varieties are generally similar in shape to cotton walnuts, with the difference being that the shoots grow rapidly, usually 24-48 cm in length, and the longest 68 cm in length. The results of the branches are oblate, slow growth, usually 5-12cm long, the longest 16cm (Figure 1). The fruit is characterized by small size (diameter 2.6cm, vertical diameter 2.8cm.) The average weight of 5.8 grams, the shell consists of more than 3 suture. Seed coat thin, easy to remove kernels white, full
