Effects of Water and Nitrogen Addition on the Seed Yield and Germination Characteristics of the Perennial Grass Leymus chinensis (Trin.) Tzvel

The reproductive characteristics of plants are likely affected by climate change e.g., changes in precipitation patterns and nitrogen deposition, but few studies have examined the effects these ecological agents selection on seed yield germination perennial grasses. Here, we conducted a multiple-year pot experiment with Leymus chinensis , common grass eastern region Eurasian steppe zone, which was grown under three water treatments without addition. L. increased highest (7.0 g/pot) 747 mm addition (10.5 g/m 2 ). Seed positively correlated heading number, tiller grain number per spike, critical factor affecting yield. percentage time to obtain 50% were environmental cues experienced mother plants.
