确定了 5 棵甜杏仁树、5 棵微苦杏仁树和 5 棵苦杏仁树的仁、叶和根中氰基化合物（苦杏仁苷和苦杏仁苷）水平之间的关系。在这些化合物的基因型之间观察到变异性。对于所有测试的基因型，仅在营养部分（根和叶）中发现了 Prunasin。苦杏仁甙仅在籽粒中检测到，主要存在于苦味基因型中。一般来说，苦核基因型的根部的核素含量高于非苦核基因型，但植物不同部位的氰化合物之间的相关性不高。虽然普那辛似乎存在于大多数杏仁根中（浓度不同），但只有苦仁基因型才能将其转化为杏仁中的苦杏仁苷。讨论了基于 prunasin 的抗布氏甲虫 Capnodis tenebrionis L. 的育种。
The relationship between the levels of cyanogenic compounds (amygdalin and prunasin) in kernels, leaves, and roots of 5 sweet-, 5 slightly bitter-, and 5 bitter-kernelled almond trees was determined. Variability was observed among the genotypes for these compounds. Prunasin was found only in the vegetative part (roots and leaves) for all genotypes tested. Amygdalin was detected only in the kernels, mainly in bitter genotypes. In general, bitter-kernelled genotypes had higher levels of prunasin in their roots than nonbitter ones, but the correlation between cyanogenic compounds in the different parts of plants was not high. While prunasin seems to be present in most almond roots (with a variable concentration) only bitter-kernelled genotypes are able to transform it into amygdalin in the kernel. Breeding for prunasin-based resistance to the buprestid beetle Capnodis tenebrionis L. is discussed.
