Cereal crop improvement programmes involve the analysis of a great number of lines every year; the availability of a simple, rapid method that would allow the identification of a trait in the early st...
Effects of water deficit stress on field performance of chickpea cultivars
Chickpea gradual water deficit grain yield LAI proline quantum yield
2011/1/12
Water deficit is one of the important factors limiting crop production in arid and semi-arid regions. This research was conducted in 2007 and 2008 to investigate field performance of three chickpea cu...
Interactive Effects of Soil Water Regime with Above-Ground Conditions on Photosynthesis in Wheat Plants:II. Combined effects of soil water deficit with low air humidity
Humidity Leaf position Photosynthesis Ribulose 1 5-bisphosphate carboxylase/oxygenase
2009/8/6
Effects of soil water deficit, low air humidity and in combination were examined at the milky stage under controlled conditions. Low air humidity which plants experienced prior to measurement affected...

In order to explore the physiological basis for the difference among plant parts in photosynthetic depression by soil water dieficit, the tissue water status was examined by using an electric circuit ...
Effects of Epibrassinolide and Abscisic Acid on Sorghum Plants Growing under Soil Water Deficit : II. Physiological basis for drought resistance induced by exogenous epibrassinolide and abscisic acid
Abscisic acid Brassinolide Cuticular transpiration Drought resistance Sorghum Stomatal transpiration
2009/7/31
It was reported that pretreatment with abscisic acid (ABA) increased the drought resistance of sorghum plants and that 22R, 23R epibrassinolide (EBR) enhanced the effects of ABA. To explore the mecha...

Abscisic acid Brassinosteroid Drought resistance Epibrassinolide Growth Root Sorghum
2009/7/31
Spray treatment with 22R, 23R epibrassinolide (EBR, 0.1 ppm) increased the length and dry weight of both the top and root of sorghum plants under various soil water conditions, although the extent of...
Sterility in Rice (Oryza Sativa L.) Subject to Drought during the Booting Stage Occurs not because of Lack of Assimilate or of Water Deficit in the Shoot but because of Dehydration of the Root Zone
Booting stage Degeneration of spikelet Dehydration Drought Oryza sativa L
2009/7/30
In rice plants a drought at the booting stage is the event most damaging to grain yield because it drastically increases sterility. Our objective was to establish what phosiological processes caused s...
