Abstract:
... We examined the relationship between shoot growth and temperature and solar radiation in macadamia (Macadamia integrifolia Maiden and Betche, M. integrifoliaxtetraphylla Johnson) as an aid to developing pruning strategies for this crop. Trees growing at Alstonville (28.9°S) in northern NSW, Australia, were pruned at various times to promote vegetative flushing under a range of environmental condit ...

Abstract:
... The root holoparasitic angiosperm Orobanche crenata is a severe constraint to the cultivation of legumes. Breeding for resistance is a difficult task. Understanding the mechanisms underlying host resistance is a fundamental issue for the genetic improvement of legumes. In this work, the temporal expression patterns of 8 defence-genes known to be involved in different metabolic pathways activated d ...

Abstract:
... The quantitative trait loci (QTLs) on chromosomes 7BL and 3BS from Halberd have been used as a major source of tolerance to late maturity α amylase (LMA) within Australian wheat breeding programs. New simple sequence repeat (SSR) markers identified from the sequencing of Bacterial Artificial Chromosome (BAC) clones from the wheat cv. Renan library, and known SSRs, were used to characterise these m ...

Abstract:
... Anthracnose is a major disease of lupins in Western Australia (WA). The disease wiped out the WA albus lupin industry in 1996 and since then, anthracnose resistance has been a major focus for WA lupin breeding. In an endeavour to find a source of resistance to anthracnose, all available germplasm in WA was screened against anthracnose in New Zealand over the summer of 1997 and 1998, and resistance ...

Trifolium resupinatum; runoff; annuals; irrigation water; perennials; feeds; soil water content; pastures; farmers; drought; alfalfa; forage; growing season; production costs; rain; dairies; irrigation requirement; dairy industry; forage production; Australia
Abstract:
... The dairy industry in Victoria, Australia, uses more than half the state's irrigation water, mainly for growing pasture. Information on the comparative water use of forage systems would be useful for dairy farmers aiming to optimise their forage production under conditions of limited water availability. However, there are few data comparing water use under similar management and weather conditions ...

Abstract:
... We evaluated arbuscular mycorrhizal fungi (AMF) for enhancement of irrigated olive (Olea europaea L.) tree growth and vigour under arid horticultural conditions. The response of 12 common commercial olive cultivars to AMF (Glomus mosseae and Glomus intraradices) inoculation was measured in a nursery experiment. Long-term post-transplanting response to AMF inoculation (G. intraradices alone or G. i ...

... Subterranean clover mottle virus (SCMoV), which causes an important disease of annual clover pastures, was inoculated to the annual pasture legume Medicago truncatula, a model legume species used to help understand legume genome structure and function. Two hundred and nine accessions representing the core collection of M. truncatula were inoculated with infective sap containing SCMoV to determine ...

buds; crop yield; nutrient content; nutrient transport; nutrients; plant growth; roots; saline soils; salt stress; salt tolerance; shoots; sodium chloride; soil salinity; sprouting; sugarcane
Abstract:
... Soil salinity suppresses plant growth by reducing, among other factors, the acquisition of essential nutrients by roots and their transport to shoots. However, studies on the intra-specific differences in nutrient accumulation under salinity are scarce. A study was conducted to determine varietal differences in (a) nodal mineral concentrations and (b) sprouting, growth, and nutrient acquisition by ...

chemical control; crop damage; cropping systems; crops; disease control; herbicide resistance; pesticide application; precision agriculture; risk; row spacing; stubble; tillage; weed control
Abstract:
... Growing agricultural crops in wide row spacings has been widely adopted to conserve water, to control pests and diseases, and to minimise problems associated with sowing into stubble. The development of herbicide resistance combined with the advent of precision agriculture has resulted in a further reason for wide row spacings to be adopted: weed control. Increased row spacing enables two differen ...

Abstract:
... Profiles of fruit density, fruit size, and oil content were measured on 12 occasions in 7 olive orchards in Spain and 2 in Australia. Orchard structure varied widely. Height ranged from 2.0 to 5.5m, row spacing from 3 to 6m, and canopy width from 0.7 to 3m. Most orchards were oriented north-south (N-S) but one in Spain was oriented close to east-west (E-W) (20° NE-SW). All orchards in Spain were c ...
