Taschenbuch. Zustand: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Tomato (Lycopersicon esculentum Mill.) is an important vegetable crop grown through out the world under outdoor and indoor conditions. The crop is subjected to attack by various diseases and early blight caused by Alternaria solani (Ellis and Martin) Sorauer is most destructive one. Field screening of 81 tomato genotypes against early blight indicated that 11 genotypes were highly resistant, 23 resistant, 22 moderately resistant, 15 susceptible and 10 highly susceptible. Genotypes resistant to early blight gave much higher yield as compared to susceptible ones. All the test fungicides (Dithene M-45, Blitox-50 and Kavach) and neem pesticides (Bioneem, Fortune and Nimbicidine) exerted possitive effect on disease control and yield increase of the test host plants. Highly resistant wild species, L. pimpinellifolium and L. peruvianum had higher quantitiy of sugars, phenols, vitamin 'C, total free amino acids, total crude protein, chlorophyll and NPK content in comparison to susceptible genotypes at pre-infectional stage, whereas, after-infection a marked reduction in the level of these constituents was observed in susceptible genotypes than in resistant genotypes.…

Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Genome of PRSV pathotypes P (10317 nt) and W (10335 nt) from India were completely sequenced. Their genome architecture was similar to other 15 isloates from the rest of the world. Comparative sequence analysis revealed that pathotypes P and W shared high degree of sequence identity both at nucleotide (89%) and aminoacid (94%) levels. Sequence comparison of individual cistrons (except P1) also revealed similar trend. The P1 region was most divergent (upto 33%) and this could be attributed to geographical and host adaptation of PRSV. Cistron by cistron sequence comparison of PRSV pathotypes P and W from India with available 15 sequences and phylogenetic analysis based on full genome polyprotein revealed two distinct groupings of Asian and American isolates, although PRSV India clustered along with the American isolates. Putative recombination sites (24) were available through out the genomes, except in small 6K2 region. Maximum numbers of recombination sites were seen in 5 UTR and P1 region and has been speculated to be the most vulnerable region in shaping PRSV genome. 180 pp. Englisch.…

Taschenbuch. Zustand: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - La tomate (Lycopersicon esculentum Mill.) est une culture maraîchère importante, cultivée partout dans le monde en plein champ et sous abri. Cette culture est exposée à diverses maladies, parmi lesquelles le mildiou causé par Alternaria solani (Ellis et Martin) Sorauer est la plus destructrice. Un criblage en plein champ de 81 génotypes de tomates contre le mildiou a montré que 11 génotypes étaient très résistants, 23 résistants, 22 modérément résistants, 15 sensibles et 10 très sensibles. Les génotypes résistants au mildiou ont donné un rendement bien supérieur à celui des génotypes sensibles. Tous les fongicides testés (Dithene M-45, Blitox-50 et Kavach) et les pesticides à base de neem (Bioneem, Fortune et Nimbicidine) ont eu un effet positif sur la lutte contre la maladie et l'augmentation du rendement des plantes hôtes testées. Les espèces sauvages hautement résistantes, L. pimpinellifolium et L. peruvianum, présentaient des teneurs plus élevées en sucres, phénols, vitamine C, acides aminés libres totaux, protéines brutes totales, chlorophylle et NPK par rapport aux génotypes sensibles au stade pré-infectieux, tandis qu'après l'infection, une réduction marquée du niveau de ces constituants a été observée chez les génotypes sensibles par rapport aux génotypes résistants.…

Taschenbuch. Zustand: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Il pomodoro (Lycopersicon esculentum Mill.) è un'importante coltura orticola coltivata in tutto il mondo sia in pieno campo che in serra. La coltura è soggetta all'attacco di varie malattie e la peronospora causata dall'Alternaria solani (Ellis e Martin) Sorauer è quella più distruttiva. Uno screening in campo di 81 genotipi di pomodoro contro la peronospora ha indicato che 11 genotipi erano altamente resistenti, 23 resistenti, 22 moderatamente resistenti, 15 sensibili e 10 altamente sensibili. I genotipi resistenti alla peronospora hanno dato una resa molto più elevata rispetto a quelli sensibili. Tutti i fungicidi testati (Dithene M-45, Blitox-50 e Kavach) e i pesticidi a base di neem (Bioneem, Fortune e Nimbicidine) hanno esercitato un effetto positivo sul controllo della malattia e sull'aumento della resa delle piante ospiti testate. Le specie selvatiche altamente resistenti, L. pimpinellifolium e L. peruvianum, presentavano una maggiore quantità di zuccheri, fenoli, vitamina C, aminoacidi liberi totali, proteine grezze totali, clorofilla e contenuto di NPK rispetto ai genotipi sensibili nella fase pre-infettiva, mentre, dopo l'infezione, è stata osservata una marcata riduzione del livello di questi costituenti nei genotipi sensibili rispetto a quelli resistenti.…

Taschenbuch. Zustand: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - O tomate (Lycopersicon esculentum Mill.) é uma importante cultura hortícola cultivada em todo o mundo, tanto ao ar livre como em ambiente controlado. A cultura está sujeita ao ataque de várias doenças, sendo a mancha precoce causada por Alternaria solani (Ellis e Martin) Sorauer a mais destrutiva. A triagem em campo de 81 genótipos de tomate contra a mancha precoce indicou que 11 genótipos eram altamente resistentes, 23 resistentes, 22 moderadamente resistentes, 15 suscetíveis e 10 altamente suscetíveis. Os genótipos resistentes à mancha precoce apresentaram um rendimento muito superior em comparação com os suscetíveis. Todos os fungicidas testados (Dithene M-45, Blitox-50 e Kavach) e os pesticidas à base de nim (Bioneem, Fortune e Nimbicidine) exerceram um efeito positivo no controlo da doença e no aumento do rendimento das plantas hospedeiras testadas. As espécies selvagens altamente resistentes, L. pimpinellifolium e L. peruvianum, apresentaram maior quantidade de açúcares, fenóis, vitamina C, aminoácidos livres totais, proteína bruta total, clorofila e teor de NPK em comparação com os genótipos suscetíveis na fase pré-infecciosa; por outro lado, após a infecção, observou-se uma redução acentuada no nível destes constituintes nos genótipos suscetíveis em comparação com os genótipos resistentes.…
