Scarcity of water for irrigation is an alarming issue limiting crop production worldwide and is becoming increasingly severe with the passage of time in Pakistan. Rice production in Pakistan is thus, being adversely hampered by the shortage of water. The study was therefore, contemplated to determine t he effect of drought stress on some physiological and agronomic parameters of three rice cultivars naming Basmati-Super, Shaheen-Basmati and Basmati-385. The field experiment was laid out in… 

Tables from this paper

Effect of Water Stress on Morphological Traits and Yield in Rice Genotypes
TLDR
The result showed that all the morphological characters are decreased under water stress condition and the studied traits indicate as ideal for improvement through selection or molecular breeding and that they may provide a high response to water stress.
Effect of exogenously applied kinetin and glycinebetaine on metabolic and yield attributes of rice (Oryza sativa L.) under drought stress.
TLDR
Exogenous application of KIN at flowering stage could be used as an effective treatment to mimic the adverse effects of water stress in fine rice cultivars under water stress.
Influence of Water Stress on Morphology, Physiology and Yield Contributing Characteristics of Rice
TLDR
Investigation of the effect of water stress on three rice varieties in a silty clay soil indicated that approximately 2 cm water can easily be curtailed which may not affect the production of rice.
Physiological Response of Advanced Lines of Rice under Water Deficit in Campeche, Mexico
TLDR
The physiological response of rice genotypes to water stress was researched and the grain yield and its components, leaf area, total root biomass, and transpiration efficiency were found to be greater under irrigation conditions than under drought.
Utilization of genetic diversity and marker-trait to improve drought tolerance in rice (Oryza sativa L.).
TLDR
Combining information from phenotypic traits, genetic diversity analysis, and QTL analysis was very useful in identifying the true drought-tolerant rice genotypes that can be used for crossing in the future breeding program.
Assessment of relative gene expression of wdhn5 in wild and agronomy wheat genotypes under drought stress conditions
TLDR
Results of real time PCR on relative expression of wdhn5 gene showed that its expression in Tauschii and Bolani tolerant cultivars in 40% of field capacity increased significantly which could indicate the importance of this gene in drought stress conditions.
Water-efficient rice performances under drought stress conditions
TLDR
Evaluating the adaptation response of production, morphological, and physiological character of several water-efficient rice varieties under drought stress in the field showed that upland rice varieties were more tolerant to drought stress and had a higher water use efficiency than lowland rice varieties.
Assessment of comparative effects of sodium chloride stress on various growth parameters in different verities of rice (Oryza sativa L.)
TLDR
It can be concluded that the Swat Sella rice variety is better adopted and can grow better in salinity compared to Punjab variety that grows best in non-saline conditions.
INDUCTION OF DROUGHT TOLERANCE IN ZEA MAYS L . BY FOLIAR APPLICATION OF TRIACONTANOL
In the present study, we assessed the effect of foliar application of triacontanol (TRIA) on various growth and physiochemical parameters of two maize (Zea mays L.) cultivars (cv. MMRI-Yellow and cv.

Effects of Drought Stress on Growth and Yield of Rice (Oryza sativa L.) Cultivars and Accumulation of Proline and Soluble Sugars in Sheath and Blades of Their Different Ages Leaves
TLDR
Zayandeh-Rood cultivar, in which originated from local cultivars, have higher ability in solute accumulation such as proline and total carbohydrates than the other new lines, and it may be suggested that thesolute accumulation is one of the mechanisms for drought tolerance in rice.
WATER DEFICIT STRESS IN THE REPRODUCTIVE STAGE OF FOUR INDICA RICE (ORYZA SATIVA L.) GENOTYPES
TLDR
From the results, KDML105 and NSG19 were identified as water deficit-tolerant, and PT1 and IR20 asWater deficit-susceptible.
Genotypic Variation in Response of Rainfed Lowland Rice to Prolonged Drought and Rewatering
TLDR
Patterns of response of rice seedlings to drought and rewatering in the greenhouse should help to explain the patterns of adaptation of rainfed lowland rice in the field and selection for drought recovery ability should be an advantageous strategy for early season drought.
