Soil rock content influences the maximum seedling emergence depth of a dominant arid zone grass

摘要: We aimed to understand the influence of differing soil rock content on seedling emergence a dominant arid zone grass critical mine restoration (Triodia pungens R.Br.). assessed whether mortality resulting from seedlings failing navigate rocky soils contributes meaningfully failed recruitment and maximum depth. Cleaned seeds florets (the natural dispersal unit) were buried at discrete depths 0, 5, 10, 15, 20, 30, 40 mm in three soil-rock matrices varying (soil sieved 20 mm) is likely restricted by rocks imposing physical barrier recruitment.
