Summer Dormancy Expression In The Australian Native Grass Elymus Scaber, Matthew Newell, Richard C. Hayes, Jim Virgona, Philip Larkin
Summer Dormancy Expression In The Australian Native Grass Elymus Scaber, Matthew Newell, Richard C. Hayes, Jim Virgona, Philip Larkin
IGC Proceedings (1997-2023)
Complete summer dormancy is associated with plant senescence in late spring-summer even though soil moisture is non-limiting. The trait is well understood in exotic temperate grasses for persistence in environments which experience frequent summer droughts (Annicchiarico et al. 2011). However, the trait appears to be uncommon in Australian native grasses (Culvenor 2009). The C3 native perennial grass, Elymus scaber, is broadly adapted across a wide range of climatic zones and soil types in south eastern Australia (Johnston et al. 2001) and has been described as displaying strong summer dormancy (Mitchell et al. 2001). However, the reports …

In recent years, deferred grazing (no defoliation of pastures for a period generally from spring to late summer or autumn) has been widely adopted to rejuvenate degraded native pastures in marginal land classes such as steep hill country in western Victoria, Australia. One of the important features of deferred grazing is the increase of seed production over summer and autumn, which could potentially lead to natural regeneration and improved groundcover by pasture plants (Nie et al. 1999). While increasing seed numbers in the soil seed bank following deferred grazing were reported (Nie and Mitchell 2006), there has been little …
Seed Ecology Of Microlaena Stipoides In Grazing Systems Of South-Eastern Australia, Meredith L. Mitchell, James M. Virgona, Joe Jacobs, David R. Kemp
Seed Ecology Of Microlaena Stipoides In Grazing Systems Of South-Eastern Australia, Meredith L. Mitchell, James M. Virgona, Joe Jacobs, David R. Kemp

Microlaena stipoides var. stipoides (Labill.) R.Br. (Microlaena) is a tufted C3 native Australian perennial grass with a short rhizome that can form dense lawns. Microlaena has a wide geographic distribution throughout southern Australia, particularly in the temperate, high-rainfall tableland areas (> 550 mm AAR) of south-eastern and western Australia where is considered to be important for the grazing industries because of its extended growing season in higher rainfall areas, persistence over many years and persistence through drought. Although Microlaena has an important role in the stability of grazed native pastures, little is known about this grass in grazed communities. This …

Indian agriculture has traditionally been a mixed farming system since ancient times with integration of arable crops and livestock. It provides employment and livelihood to 70% of the rural population. Livestock are predominantly cattle and small ruminants that graze extensively on rangelands/pasturelands and common property resources (CPRs). CPRs occupy approximately 54 million ha area including permanent pastures in the alpine and temperate parts as well as seasonal grazing lands and wastelands. The productivity and carrying capacity of tropical degraded grasslands is very low, the average carrying capacity being 1.0, 0.7, 0.7 Adult Cattle Unit (ACU)/ha in semi-arid, arid and hill …
