Effect of Rust Disease on Photosynthetic Rate of Wheat Plant

Abstract: Abstract:The purpose of this research was to study the influence of rust diseases on photosynthetic rate of the created local varieties and introduced variety samples of wheat. Experiment was carried out with two variants-control and 25% Tilt treatment. The 25% solution of Tilt was used to prevent disease infection. The photosynthetic rate was measured by T-type URAS-2 infrared gas analyzer (made in Germany). Disease infection rate was determined based on the Cobby balling scale. Ontogenetic and daily rate of … Show more

“…These reports are in line with the results from this study where AUDPC_Sr negatively correlated with GY, TKW, BM and GFP. The results suggested that, GY, TKW and BM reduced with the increase in stem rust severity due to the negative influence of disease to plant metabolic process [49,50].…”

“…En este sentido los hallazgos de esta investigación concuerdan con las observaciones hechas por estos autores, ya que se evidenció la perdida de la autofluorescencia de la clorofila en la longitud de emisión correspondiente al rojo en los tejidos afectados por la infección causada por P. nakanishikii, lo cual refleja el compromiso y daño de los tejidos fotosintéticos y el afecto adverso sobre los cloroplastos durante el proceso de patogénesis. El efecto de los patógenos biotróficos como las royas sobre la fotosíntesis y los contenidos de clorofila, han sido observados en varios grupos de plantas, incluidas las gramíneas (Scholes & Rolfe, 2009;Zhao, Glynn, Glaz, Comstock, & Sood, 2011;Abdulbagiyeva, Zamanov, Talai, & Allahverdiyev, 2015;Walters, 2015). Es interesante indicar que en C. citratus los tejidos parenquimatosos de pared primaria de las regiones afectadas por la necrosis celular debido al desarrollo de la roya pierden la autofluorescencia azul claro característica y que probablemente se puede atribuir a la lignificación parcial y/o la presencia de ácido ferúlico en estas células; reflejando el efecto del patógeno sobre este tipo de moléculas presentes en la pared celular (Mahlein et al, 2018).…”
