摘要测定了51株白色三叶草（Trifolium repens L.）在温室中在统一条件下生长的品种。HCN含量在120 ~ 1110 ngHCN/g干物质之间。在新西兰农艺学上成功的品种，以及新西兰原产的品种，主要是高氰。有证据表明，在“草原Kopu”和“阿兰”的氰化物含量下降，从第一代种子提出的植物相比，植物育种或基本的种子。这种下降可能是由于低HCN居民三叶草的种子作物的污染。白色三叶草中的碘浓度范围为0.08 - 0.21 μg I/g DM，77%的值低于0.12 μg I/g DM。I和HCN浓度之间没有相关性。通过选择提高白色三叶草中碘含量来改善砧木的碘营养似乎没有什么潜力。研究了生氰三叶草对Meta的影响。
Abstract Hydrogen cyanide (HCN) and iodine (I) concentrations in the herbage were determined for 51 white clover (Trifolium repens L.) cultivars that had been grown under uniform conditions in a glasshouse. HCN contents ranged from 120 to 1110ngHCN/g dry matter (DM). Cultivars that are agronomically successful in New Zealand, and cultivars of New Zealand origin, were mainly highly cyanogenic. There was evidence in ‘Grasslands Kopu’ and ‘Aran’ of a decline in cyanide content in plants raised from first generation seed, compared to plants from Breeders or Basic seed. This decline may result in part from contamination of seed crops by low HCN resident clovers. Iodine concentration in the white clovers ranged from 0.08 to 0.21 μg I/g DM with 77% of values being below 0.12 μg I/g DM. There was no correlation between I and HCN concentrations. It seems there is little potential to improve the I nutrition of stock by selecting for increased I content in white clover. The influence of cyanogenic clover on the meta...
