A variety of adverse conditions including drought stress severely affect rice production. Root system plays a critical role in drought avoidance, which is one of the major mechanisms of drought resistance. In this study, we adopted genome-wide association study (GWAS) to dissect the genetic basis controlling various root traits by using a natural population consisting of 529 representative rice...

A study to determine whether root rot infestations can be detected using high spatial resolution digital multispectral video (DMSV) data was conducted in the Imperial Valley of California. DMSV data were collected on two dates over 25 fields during the summer of 1999 using a light aircraft. The DMSV images included four spectral bands centered on 530 nm, 570 nm, 650 nm and 750 nm, with nominal ...

Pulmonary function test results of individuals with the acquired immunodeficiency syndrome (AIDS) were analyzed to determine the prevalence of abnormally low forced expiratory flow rates and bronchial hyperreactivity. Of 99 individuals with AIDS, a total of 44 (44 percent) had either low forced expiratory flow rates or a significant response to inhaled bronchodilator. Thirty-one (31 percent) in...

The therapeutic results in acute myocardial infarction for two periods hnmediately preceding (pre-CCU) and after (post-CCU) establishment of a coronary care unit were compared. One hundred cases of proved myocardial infarction were selected at random from each time period. The coronary care unit reduced gross mortality from 33 percent (pre-CCU) to 16 percent (post-CCU). The reduction in mortali...

a study was conducted to evaluate the effects of moisture limitation on yield and dry matter distribution between shoot and root of triticale genotypes. this study was performed using a factorial experiment based on completely randomized design with four replications, in agricultural college of ferdowsi university of mashhad greenhouse during 2009. treatments were two available soil water inclu...
