Intervarietal ionic composition changes in barley under salt stress cultivars tested reacted quite differently to the stress situation. Growth and ionic content were followed in three to four plant parts, such as old leaves, young leaves, sheath and the ear as it appeared. The best growing plants also showed the most efficient salt segregation between their differe

Boron tolerance in Australian varieties of wheat and barleyered significantly between varieties, as did boron concentration in tops, and in grain at maturity. The relative order of yields of barley and wheat varieties varied between the sites of different soil boron status..In wheat, both specific tolerance (relatively high yield despite accumulation of hig

Tolerances of Old World bluestems to an acid soil high in exchangeable aluminum 4.1 and limed at pH 5.3. Three strains of weeping lovegrass (.) and El Reno side-oats grama grass (.) were also included as indicators of acid and alkaline soil tolerance, respectively. At pH 4.1 only 5 of the 29 bluestems and the 3 weeping lovegrasses produced measurable yields of tops or roots. T

Mohammed Bashir Umar,Usman Harunant parts. It is our aim to analyse in further detail (metabolism) how these plants differ from each other to explain their better salt resistance. There were some genetic links between these cultivars, but the genetic background was rather confused, due to uncontrolled intercrossing with other unknown types.

Hydrogen and aluminium tolerancexicity in a number of species and nodulation in clover is more sensitive than growth of the host plant to Al. Decrease in soil pH is associated with significant increases in exchangeable Al. The breeding of Al tolerant wheats in Australia involves a backcross programme utilizing the transfer of tolerance from the Brazilian cultivar Carazinho.
