Stem Reserve Mobilisation Supports Wheat-grain Filling Under Heat Stress
The superior capacity of V5 for grain filling from mobilised stem reserves is a consti- tutive trait which supports grain filling under heat stress which can be tested for by chemical desiccation of plants under non-stressed conditions.
An evaluation of seed and seedling drought tolerance screening tests in wheat
It is concluded that tolerance to water stress in growing seedlings can be screened for by using PEG-containing nutrient solutions, and can not be predicted from germination tests in osmotica.
The effect of dwarfing genes on sorghum grain filling from remobilized stem reserves, under stress
The drought response of landraces of wheat from the northern Negev Desert in Israel
Diverse landraces of wheat, collected from the semi-arid Northern Negev desert in Israel were considered as a potential genetic resource of drought resistance for wheat breeding and were evaluated for their reponses to drought stress in agronomical and physiological terms.
Mass selection of wheat for grain filling without transient photosynthesis
The results are interpreted to show that selection under potential conditions and under chemical desiccation operate on two different sources for grain filling, namely transient photosynthesis and stem reserve utilization, respectively.
The Grain Quality of Landraces of Wheat as Compared with Modern Cultivars
Gram protein content and/or quality was not maximized in modern cultivars and its improvement was deemed possible by introgression from the best landraces in this respect, indicating that modern wheat breeding maximized kernel weight and carotin content, as compared with the tested landraced.
Isolation and characterization of variant wheat cultivars for ABA sensitivity
It is concluded that, while ABA sensitivity is expressed in the growth of plants challenged by ABA in the root medium, the control of sensitivity resides, at least partly, in the leaf.
Wheat seed endosperm utilization under heat stress and its relation to thermotolerance in the autotrophic plant

In terms of plant water status and mean daily biomass production, varieties were more drought resistant than hybrids, however, the physiological superiority of the varieties under drought stress did not result in a higher grain yield because of their inherent relatively poor harvest index.
