Abstract We report physiological and anatomical characteristics of water transport across roots grown in soil two cultivars grapevine (Vitis vinifera) differing response to stress (Grenache, isohydric; Chardonnay, anisohydric). Both have similar root hydraulic conductances (L o; normalized dry weight) that change diurnally. There is a positive correlation between L o transpiration. Under stress, both reduced minimum daily (predawn) attributed the development apoplastic barriers....
We investigated how root hydraulic conductance (normalized to dry weight, Lo ) is regulated by the shoot. Shoot topping (about 30% reduction in leaf area) reduced of grapevine (Vitis vinifera L.), soybean (Glycine max L.) and maize (Zea mays 50 60%. More detailed investigations with showed that was not correlated area, shading or cutting single leaves had a similar effect. Percentage largest when initial high soybean. Inhibition weak acid (low pH) smaller after shoot damage shading. The half...
Under saline conditions, plant growth is depressed via osmotic stress and salt can accumulate in leaves leading to further depression of due reduced photosynthesis gas exchange. Aquaporins are proposed have a major role plants their impact on root water uptake leaf In this study, soybean plasma membrane intrinsic protein 1;6 (GmPIP1;6) was constitutively overexpressed evaluate the function GmPIP1;6 regulation tolerance soybean.GmPIP1;6 highly expressed roots as well reproductive tissues...
Fourteen wheat (Triticum aestivum L.) cultivars released to Australian growers over the last century were examined determine impact of crop breeding on competitive ability with weeds. In 1999 and 2000 weed used in field study was annual ryegrass (Lolium rigidum Gaud.) 2001 oats (Avena sativa cv. Marloo) weedy competitor. 2 out 3 years (1999 2001), when Puccinia recondita (leaf rust) infection not a problem, there consistent trends for improvement yielding through effort time. these seasons...
Competitive ability of wheat is influenced by a range attributes such as plant height, tiller number, and light interception. This study focused on the effect height weed competitiveness set near-isogenic lines (NILs). The included seven bread (Triticum aestivium L.) six durum (T. turgidum cultivars, each having semidwarf tall line. These were examined in field experiments conducted over two growing seasons. Oats (Avena sativa 'Marloo') used mimic sown with various traits recorded. NILs more...
We report physiological, anatomical and molecular differences in two economically important grapevine (Vitis vinifera L.) cultivars cv. Grenache (near-isohydric) Chardonnay (anisohydric) their response to water-stress induced cavitation. The aim of the study was compare organ vulnerability (petiole stem) cavitation by measuring ultrasonic acoustic emissions (UAE) percent loss conductance (PLC) potted grapevines subject onset water-stress.
