TL;DR: This review considers the issue of targeting plants for forage/fodder production in landscapes affected by dryland salinity, and two principal factors that affect saltland capability—salinity and waterlogging, and suggests three critical questions that need to be answered.

TL;DR: In this article, the authors review the major issues that impact upon the development of improved fodder species for saline environments across temperate Australia and make recommendations for research that should ensure that Australian producers have access to a new array of productive fodder species suited to saline environments.
Abstract: This paper reviews the major issues that impact upon the development of improved fodder species for saline environments across temperate Australia. It describes past and present research that has been, or is being, undertaken towards improvements in salt tolerance in forage species within Australia in relation to the principal regions where salinity occurs. It includes a discussion on the mechanisms of salt tolerance in plants. An extensive list of known or potential salt-tolerant fodder species is provided and the key opportunities for advancement within each of the 4 major forage groups: grasses, legumes, herbs and shrubs are discussed. Constraints to developing new salt and waterlogging tolerant fodder species are identified. A number of recommendations are made for research that should ensure that Australian producers have access to a new array of productive fodder species suited to saline environments.

Journal ArticleDOI
TL;DR: Results showed genotype, irrigation and their interaction had a significant effect on polyphenols and antioxidant activity, and both irrigation treatments and genotype need to be considered by sorghum breeders and farmers to produce grain with the required levels of polyphenolics and antioxidants activity for targeted end-use.

TL;DR: The results provide new information on the effects of HT on specific polyphenols in various Australian sorghum genotypes, which might be used as a guide to grow high antioxidant Sorghum grains under projected high temperature in the future.
Abstract: Polyphenols in sorghum grains are a source of dietary antioxidants. Polyphenols in six diverse sorghum genotypes grown under two day/night temperature regimes of optimal temperature (OT, 32/21 °C and high temperature (HT, 38/21 °C) were investigated. A total of 23 phenolic compounds were positively or tentatively identified by HPLC-DAD-ESIMS. Compared with other pigmented types, the phenolic profile of white sorghum PI563516 was simpler, since fewer polyphenols were detected. Brown sorghum IS 8525 had the highest levels of caffeic and ferulic acid, but apigenin and luteolin were not detected. Free luteolinidin and apigeninidin levels were lower under HT than OT across all genotypes (p ≤ 0.05), suggesting HT could have inhibited 3-deoxyanthocyanidins formation. These results provide new information on the effects of HT on specific polyphenols in various Australian sorghum genotypes, which might be used as a guide to grow high antioxidant sorghum grains under projected high temperature in the future.

Journal ArticleDOI
TL;DR: It is suggested that varieties with reduced or delayed onset of lignification are important in the prevailing colder, wetter climates of the more northerly latitudes, and the higher seed rate led to better weed suppression and higher fibre yields in all varieties.

TL;DR: The use of halophytes may be a viable commercial alternative to ease pressure on the requirement of good quality land and water for conventional cropping systems and the utilization of land degraded by salinity as mentioned in this paper.

TL;DR: It is concluded that more in-depth electrophysiological and molecular studies are needed to reveal the identity of membrane transport systems and better understand what appears to be the complex and highly orchestrated regulation of ion transport and sequestration in halophytes.
Abstract: The increasing problem of global land salinisation and associated multibillion dollar losses in crop production require a better understanding of key physiological mechanisms conferring salinity tolerance in crops. The effective way of gaining such knowledge comes from studying halophytes. Halophytes have always attracted the attention of plant physiologists, due to their remarkable ability to tolerate and even benefit from salt concentrations that kill most other plant species. At the very least, halophytes may provide genes that allow transgenic conference of salinity tolerance to crops. In addition, some halophytes have already been tested as vegetable, forage and oilseed crops in agronomic field trials, whilst others already show good potential to be developed as crops. Surprisingly, our knowledge of fundamental ionic and molecular mechanisms conferring salinity tolerance in halophytes is rather limited and, at best, is restricted to several model species. This chapter summarises the current knowledge of physiological mechanisms regulating ion uptake and sequestration in halophytes. The following topics are covered: specific anatomical and morphological features of halophytes; tissue- and organ-specific ion compartmentation; mechanisms of osmotic adjustment in halophytes; radial ion transport in halophytes roots; mechanisms of Na+ and K+ loading into the xylem; Na+ sequestration in vacuoles in roots and leaf cells; ion transport in guard cells; control of ion fluxes into salt glands and bladders; and oxidative signalling and damage repair in halophytes. It is concluded that more in-depth electrophysiological and molecular studies are needed to reveal the identity of membrane transport systems and better understand what appears to be the complex and highly orchestrated regulation of ion transport and sequestration in halophytes.
