Abstract:
A method for evaluating sheath blight resistance is provided to obtain an objective evaluation result conveniently regarding the sheath blight resistance, raise the inoculation efficiency of pathogenic bacteria of the sheath blight and improve the resistance evaluation method, thereby contributing to breed a species with resistance to the sheath blight. A method for evaluating sheath blight resistance comprises the steps of: (a) after inoculating a liquid culture mycelia of Rhizoctonia solani into rice, sealing the inoculation portion tightly using a shielding film such as aluminum foil for maintaining moisture required for vitality of the mycelia; and (b) after cultivating the mycelia inoculated rice until disease is progressed into branches and leaves, evaluating the resistance degree, wherein the resistance degree evaluation is performed by evaluating the attack degree of all leaves sheaths corresponding to the inoculated stem with 0 to 9 steps and calculating a virus infection rate of the inoculated stem in accordance with a following calculating formula of the virus infection rate being equal to (9n9+7n7+5n5+3n3+1n1+0n0)/9N Î 100(wherein each of the n0 to n9 is a number of leaves sheaths corresponding to each of the attack degree evaluated at the mycelia inoculated stem, and the N is the total leaves sheaths of the mycelia inoculated stem).
Abstract:
본 발명은 2종 이상의 농작물 종자들에 대해 동시에 종자전염병 저항성 품종 여부를 대량으로 검정하는 방법을 제공한다. 본 발명에 따른 검정 방법은 (a) 처리액이 통과할 수 있는 제1 용기 2개 이상 또는 처리액이 통과할 수 있으면서 2개 이상의 구획을 갖는 제2 용기를 준비하는 단계; (b) 2종 이상의 농작물 종자들을 상기 용기에 치상하되, 서로 다른 종자들은 서로 다른 제1 용기 또는 제2 용기의 서로 다른 구획 내에 치상하는 단계; (c) 2종 이상의 농작물 종자들이 치상된 용기(들)을 종자전염병 병원균 현탁액이 수용되어 있는 욕조(bath)에 동시에 침지하여 접종하는 단계; 및 (d) 제1용기별 또는 제2용기의 각 구획별로 전단계에서 접종된 종자들을 육묘용 상자에 구별하여 파종하는 단계를 포함한다.
Abstract:
The present invention relates to functional baby powder using rice and a manufacturing method thereof. The present invention comprises a step of dehusking brown rice, finely grinding the dehusked rice, and coating thereby commercializing in order to develop rice as baby powder. The prevent invention is characterized by manufacturing excellent rice baby powder through a process of removing fats in order to prevent aggregatio onf the powder; obtaining white powder; selecting an optimal particle size which is proper for processing while having antioxidation activity and whitening activity of rice powder; and improving touch feeling and reducing moisture absorption rate by essential oil and silicon oil coating.
