Foolish seedling disease of rice led to the discovery of options (a) abscisic acid (b) cytokinin (c) 2,4-d (d) gibberellin correct answer: gibberellin explanation: no explanation available. Foolish seedling disease causes a strong elongation of rice stems and leaves and eventually causes them to topple over in 1926, japanese scientist eiichi kurosawa identified that foolish seedling disease was caused by the fungus gibberella fujikuroi [4. Historically, ga was first identified in the pathogenic fungus gibberella fujikuroi, the causal agent of the 'foolish-seedling' disease of rice, causing excessive elongation of infected plants (yabuta and sumiki, 1938.
Some medical terms used in old records diseases are generally identified by signs and symptoms many unrelated diseases have the same symptoms - fever, chills. Based on the features of rice foolish seedling disease and damping-off, the present invention selects systemic disinfectant and protective disinfectant to re-compound the re-compounded disinfectant. Gibberellins were first isolated from a fungus, gibberella fujikuroi, and were found to be the cause of bakanae disease (a disease of rice, known in japan as 'foolish seedling disease'), in which affected plants grow unusually tall but seldom survive to maturity. Foolish seedling disease see bakanae disease source for information on foolish seedling disease: a dictionary of plant sciences dictionary.
Ms - 1 of 10 mississippi summary of plant protection regulations updated july 2016 foolish seedling disease of rice/bakanae disease, gibberella fujikuroi. In 1926, the japanese biologist eiichi kurosawa showed that the bakanae (foolish seedling) disease of rice was caused by a substance produced by the fungus gibberella fujikori the substance was named gibberellin and was shown to cause elongation of stem tissues. Gibberellins foolish seedling disease in rice causes plants to grow rapidly and from bio 101 at johns hopkins university.
Ga was originally identified from the necrotrophic fungus gibberella fujikuroi (fusarium moniliforme) , the causal agent of the bakanae or foolish-seedling disease of rice disease symptoms include extensive seedling elongation with slender leaves and cause a drastic reduction in rice crop yieds. The so called foolish seedling a disease first characterized in japan which is due to too much what is gibberellin's complementary stimulating hormone. What is coordination in plants (foolish seedling) disease caused by gibberella fujikuroi these are second important growth hormones found in plants normally. Another name is foolish seedling disease it gets that name because the seeds can be infected, leading to disparate outcomes for the plant there are not many diseases that initiate similar symptoms as bakanae.
Bakanae (バカナエ) (pronounced ba-ka-na-eh) or bakanae disease(馬鹿苗病, バカナエビョウ, bakanae-byou), from the japanese for foolish seedling, is a disease that infects the rice plant. The meaning of bakanae is ''foolish seedling of rice'' but this disease is very common in north america, africa and asia the main reason of abnormal elongation of rice plants is that in perfect stage ( gibberella fujikuroi ) the pathogen produces a growth hormone named gibberellic acid into the host tissues. This disease was called the foolish seedling disease or bakanae e kurosawa found that gibberella fujikuroi is the causative organism of this disease which is a fungus. Physiological role of phytohormones of the foolish seedling disease of rice, causing excessive elongation of infected plants  they are required for various.
Pro-am seedling kits seedling heat mats brassica pests & diseases this disease is best prevented through proper crop rotation. 2014 ismab presentation - classification of foolish seedling disease for rice plants single seedling: final year projects| fast and accurate detection and classification of plant diseases.

A) foolish seedling disease of rice or bakanae disease b) damping off seedling disease of rice or bakanae disease c) fungal blight disease of rice or bakanae disease.
Icar jrf mock test on plant growth regulators (evergreen questions) part 2 by agriglance on march 17, 2017. Bakane disease from the japanese for foolish seedling, is a disease that infects the rice plant it is caused by the fungus gibberella fujikuroi, the metabolism of which produces a surplus of gibberellic acid. The condition was called foolish seedling disease, and after many years of research, this natural occurring plant hormone was identified as gibberellic acid or ga3 the direct benefits of ga3 are that it helps regulate plant growth, rapid seed germination, and plant resistance to cold and disease in almost all vegetable, fruit and flowers. Foolish-seedling disease was traced to the fungus gibberella fujikuroi, which produces substances now known as gibberellins more than 50 different gibberellins have been isolated and identified the most common is gibberellic acid.
