In order to conform to the actual production, defect part is randomly put right, side and back to the acquisition probe when the hyperspectral images of external defects potatoes are acquired. Three hundred fifteen potatoes were bought in farmers market as research object, and semi-transmission hyperspectral image acquisition system was constructed to acquire the hyperspectral images of normal external defects (bud and green rind) and internal defect (hollow heart) potatoes. The present paper put forward a non-destructive detection method which combines semi-transmission hyperspectral imaging technology with manifold learning dimension reduction algorithm and least squares support vector machine (LSSVM) to recognize internal and external defects in potatoes simultaneously. Huang, Tao Li, Xiao-yu Jin, Rui Ku, Jing Xu, Sen-miao Xu, Meng-ling Wu, Zhen-zhong Kong, De-guo Starting in the 1990â€™s, the International Potato Center (CIP)â€™s integrated pest management team for potato late blight (IPM-LB) realized the importance of addressing the management of this complex potato disease by combining crop protection and management sciences, with social and behavioral science. This (look value is more relevant to what is happening on the international market.Īddressing the human and technical dimensions of potato IPM using farmer field schools (FFS): CIP and partners' experience on late blight management During the material, given the composition of the trade balance of international trade presents strict export and import situation - in terms of value, subject to quantitative aspects of other scientific approaches. Defining aspects of this issue begin by presenting the sequence of continental entities defined by the FAO (Africa, Americas, Asia, Europe and Oceania, and then presents the study of global imports and exports, and positioning Romania in performing acts of international exchange - in the context of those mentioned above. INTERNATIONAL COMMERCIAL TRADE WITH POTATOES (2009 - 2011ĭirectory of Open Access Journals (Sweden)įull Text Available The paper refers to the situation related to the potato world trade, 2009-2011. Liquid and solid media stocks prepared according to the International Potato Center (CIP)'s protocol were used. Ī study was conducted in 20 at IRAD Bambui (Cameroon) to evaluate the rate of shooting in four improved IRAD potato varieties: Cipira, Tubira, Mafo and Bambui wonder. Shooting responses of potato ( Solanum tuberosum L.) varieties in. Unlike known IRES motifs, the PLRV IRES is located completely within the coding region of Rap1 at the center of the PLRV genome. Reporter gene expression in potato protoplasts confirmed the internal ribosome entry function. Core structural elements for internal ribosome entry include a conserved AUG codon and a downstream GGAGAGAGAGG motif with inverted symmetry. An internal ribosome entry site (IRES) with unusual structure and location was identified that regulates Rap1 translation. Within the P1 coding region we identified a 5-kDa replication-associated protein 1 (Rap1) essential for viral multiplication. Potato leafroll polerovirus (PLRV) genomic RNA acts as a polycistronic mRNA for the production of proteins P0, P1, and P2 translated from the 5â€²-proximal half of the genome.
