Under the current climate change scenario, water stress is one of the key factors that reduce the production of crops. Gibberellic acid (GA3) is an efficient endogenous plant hormone that shows a vital role in plant growth and development. Production of canola (Brassica napus L.) and its oil contents are severely affected under drought stress. The present study was conducted to investigate the potential of GA3 in alleviating drought stress in canola. Three levels of GA3 (G0 = 0 mg L−1, G1 = 100 mg L−1, and G2 = 150 mg L−1) as foliar applications were applied under two drought-stress conditions (D1 for three days of drought stress and D2 for six days of drought stress) on two canola varieties (Punjab canola and Faisal canola). Irrigation was applied after 3 weeks of germination, while foliar application of GA3 was done at intervals of 4 and 5 weeks after germination. When comparing the output of all the GA3 treatments, it was noticed that in G0 = 0 mg L−1 (control plants), water-stress conditions markedly reduced plant production and seed oil contents but increased protein and linoleic acid. With the application of G2 = 150 mg L−1, the maximum values of plant height (90.83 cm), no. of siliqua plant−1 (15.50), seed siliqua−1 (15.55), siliqua length (5.08 cm), relative water contents (77.60%), yield plant−1 (0.46 g), chlorophyll a (0.62), carotenoid contents (39.52), and oleic acid contents (60.20) were recorded under drought stress. Based on these results, it is concluded that the adverse effect of drought stress on different yield parameters of canola could be ameliorated by the exogenous application of GA3 through foliar application at a dose of 150 mg L–1. Moreover, the same treatment improves the quality parameters, i.e., the oleic acid contents of the oil, obtained from the canola.
Background: In certain situations, the radiologist may be the first physician to suggest the presence of paediatric abnormality. The need of early diagnosis of potentially life- threatening emergency conditions is now becoming one of the important contributions of ultrasound to the referring clinician. Our case presentation demonstrates the value sonographic diagnosis of meconium peritonitis. Case description: We present a case of term infant who was diagnosed to have echogenic bowel with few specks of peritoneal calcification and loculated ascites. Early detection with ultrasound led to immediate surgical intervention and patient recovered without any immediate or long term complications. Conclusion: Meconium peritonitis (MP) is a chemical peritonitis caused by fetal intestinal perforation which occurs mostly in utero. Its incidence is extremely rare, but serious neonatal morbidity or even mortality can occur if the diagnosis is not made until after birth. Prenatal diagnosis is essential in prompting early postnatal surgical intervention, and also improving neonatal outcome.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
