Summary. Glasshouse trials were conducted to examine the effect of lime or gypsum amendments on the development of cavity spot disease of carrots in soil artificially infested with Pythium coloratum. Each amendment was applied to soil from the field at 4000 or 8000 kg/ha. Lime at both application rates significantly (P<0.05) reduced the incidence of the disease. In contrast, both gypsum treatments had no effect on the incidence of cavity spot disease. There was no significant (P>0.05) difference in calcium concentration between carrot roots grown in unamended, lime- or gypsum-amended soil with or without the pathogen. Calcium did not appear to play a direct role in the reduction of cavity spot disease. Under the controlled conditions of this glasshouse trial, reduction in the incidence of cavity spot appeared to be related to the increase in soil pH associated with the application of lime. Field trials at the site of soil collection will confirm whether this mechanism is related to field reduction of the disease following liming.

Present study aimed to reveal the effects of jasmonic acid and activated charcoal on in vitro carrot plantlet regeneration by using Murashige and Skoog (MS) medium supplemented with BAP, NAA, activated charcoal and jasmonic acid at various concentrations. To serve the purpose, in vitro carrot seed germination, shoots, cotyledons, and first leaves formation of orange and purple carrot plantlets were investigated. During the experiments, root size, weight, and size of petiole diameter, hyperhydricity and callus formation rate were recorded. Experimental results revealed that combination of jasmonic acid and activated charcoal in medium had a positive effect especially on the first stage of developmental processes such as seed swelling and germination, cotyledon and first leaf formation as well as having positive effects on above-ground internode elongation, petiole and plantlet height.

Objetivando a definição da metodologia básica para a obtenção em meio de cultura sólido de embriogênese somática, em explantes de hipocótilo e folha cotiledonar de cenoura (Daucus carota L.) cultivares Kuroda, Nantes e Brasília foi realizado um experimento em condições de laboratório, utilizando-se as concentrações de 0,5; 1,0; 2,5 e 5,0 mg/litro do ácido 2,4 diclorofenoxiacético (2,4-D) e 1,0 mg/litro do ácido beta-naftoxiacético (NOA). Pelos resultados obtidos, os explantes de hipocótilo foram em geral mais adequados para o desenvolvimento do processo de embriogênese somática nos três cultivares estudados. A melhor concentração de 2,4-D na indução da embriogênese foi de 0,5 mg/litro. O tratamento com o NOA apresentou maior freqüência de embriogênese comparativamente àqueles com o 2,4-D. Houve uma resposta diferencial dos cultivares e explantes utilizados em relação aos diferentes meios de cultura.
