Hybrid potato crops can be grown from true potato seeds or from seedling tubers. True-seed-grown plants produce lower marketable tuber yield than seedling-tuber-grown plants, because of their low early vigour and distinct growth and development patterns, notably in term of main stem number and stem branching. These differences are pivotal for yield formation but their impacts on crop performance and yield are not well understood.

由真种子和幼苗块茎种植的杂交马铃薯的分枝对茎密度的响应及其对产量的影响


杂交马铃薯作物可以用真正的马铃薯种子或幼苗块茎种植。真籽种植的植物比幼苗块茎种植的植物产生较低的可销售块茎产量，因为它们的早期活力低，生长发育模式独特，特别是在主茎数和茎分枝方面。这些差异对于产量的形成至关重要，但它们对作物性能和产量的影响尚不清楚。
