Scholarcy highlights

  • Our aim was to identify the soil and environmental modifications needed to improve seed set and seed quality of the perennial forage legume perennial vetch (Vicia unijuga A
  • A 3‐yr field experiment was conducted in a subalpine zone of China to evaluate the effects of modified soil temperature and moisture conditions generated by no mulching, plastic film mulching, removal of plastic film mulching at the 30% flowering stage, and threshed barley straw mulching on seed set, mass, reserves, germination, and seedling growth
  • There were higher 100‐seed weight and seed nutrient reserves in the FM and RM treatments, accompanied by higher final germination percentage and lower time to 50% germination and greater initial seedling growth than in the control, whereas the reverse was true for the SM treatment
  • Modified soil temperature and moisture generated by mulching improved offspring performance traits of V. unijuga through an increase in HSW
  • The FM treatment provided adequate soil temperature and water resources to maximize seed set by V. unijuga plants
