1. Chilling Tolerance of Central European Maize Lines and their Factorial Crosses

Author:
Bhosale, S.U.; Rymen, B.; Beemster, G.T.S.; Melchinger, A.E.; Reif, J.C.
Source:
Annals of botany 2007 v.100 no.6 pp. 1315-1321
ISSN:
0305-7364
Subject:
chlorophyll; corn; crop production; developmental stages; field experimentation; growth chambers; hybrids; leaves; maternal effect; quantitative trait loci; testcrosses
Abstract:
... BACKGROUND AND AIMS: Chilling-stress tolerance is a prerequisite for maize production under cool climatic conditions. The main goal of this study was to evaluate the Central European dent and flint pools for chilling tolerance during heterotrophic and early autotrophic growth in field trials and growth chamber experiments. METHODS: Five European flint and five dent inbreds and their 25 factorial c ...

2. Conservative Decrease in Water Potential in Existing Leaves during New Leaf Expansion in Temperate and Tropical Evergreen Quercus Species

Author:
Saito, Takami; Naiola, B. Paul; Terashima, Ichiro

Annals of botany 2007 v.100 no.6 pp. 1229-1238
ISSN:
0305-7364
Subject:
Quercus glauca; branches; buds; leaf water potential; leaves; shoots; stomatal conductance; trees; turgor; Indonesia; Japan
Abstract:
... BACKGROUND AND AIMS: This study aimed at clarifying how the water potential gradient (ΔΨ) is maintained in the shoots of evergreen trees with expanding leaves, whose leaf water potentials at the turgor loss point (Ψtlp) are generally high. MATERIALS: The water relations were examined in current-year expanding (CEX) and 1-year-old (OLD) leaves on the same shoots in temperate (Osaka, Japan) and trop ...

3. Interactive Effects of Nutrient and Mechanical Stresses on Plant Morphology

Author:
Puijalon, Sara; Lena, Jean-Paul; Bornette, Gudrun
Source:
Annals of botany 2007 v.100 no.6 pp. 1297-1305
ISSN:
0305-7364
Subject:
aquatic plants; ground cover plants; habitats; leaves; mechanical stress; nutrient content; plant morphology; plant response; plant stress; stress response; water content; water supply
Abstract:
... BACKGROUND AND AIMS: Plant species frequently encounter multiple stresses under natural conditions, and the way they cope with these stresses is a major determinant of their ecological breadth. The way mechanical (e.g. wind, current) and resource stresses act simultaneously on plant morphological traits has been poorly addressed, even if both stresses often interact. This paper aims to assess whet ...

4. Stomatal Regulation of Photosynthesis in Apple Leaves: Evidence for Different Water-use Strategies between Two Cultivars

Author:
Massonnet, Catherine; Costes, Evelyne; Rambal, Serge; Dreyer, Erwin; Regnard, Jean Luc
Source:
Annals of botany 2007 v.100 no.6 pp. 1347-1356
ISSN:

Subject:
apples; light intensity; carbon; summer; vapor pressure; fruit trees; stomatal conductance; nitrogen content; isotopes; electron transfer; photosynthesis; leaves; climate; stomatal movement; cultivars; carboxylation; models; net assimilation rate; temperature; water use efficiency; environmental factors; growing season; leaf conductance
Abstract:
... BACKGROUND AND AIMS: Leaf responses to environmental conditions have been frequently described in fruit trees, but differences among cultivars have received little attention. This study shows that parameters of Farquhar's photosynthesis and Jarvis' stomatal conductance models differed between two apple cultivars, and examines the consequences of these differences for leaf water use efficiency. MET ...

Subject:
Litchi chinensis; amino acids; bark; branches; chymotrypsin; fruit trees; fruiting; herbaceous plants; leaves; multigene family; nitrogen; open reading frames; protein isoforms; roots; seeds; shoots; storage proteins; subtilisin; tropical and subtropical fruits; trypsin; trypsin inhibitors; vacuoles
Abstract:
... BACKGROUND AND AIMS: Vegetative storage proteins (VSPs) are commonly bioactive in herbaceous plants but few VSPs with bioactivity have been identified in trees. In addition, information on the characterization of VSPs in evergreen trees is limited. The objective of this study was to characterize the VSPs with bioactivity in evergreen trees. METHODS: The VSP in lychee (Litchi chinensis), an evergre ...
