13. Zn and K influence in fruit sizes of Valencia orange
In orange commercial farms, Zn deficiencies symptoms and small fruits were observed in Corrientes, Argentine. During four years (1995 to 1998), Valencia orange (Citrus sinensis Osb.) on Rough lemon (C. jambhiri Lush.) rootstock, implanted in 1974 in sandy soil, where six treatments were tested. Treatments varied from 1 to 3 Kg KCl.tree-1.year-1 (applied in A

14. Porta-enxertos para a limeira ácida 'Tahiti'
A lima ácida 'Tahiti' (Citrus latifolia Tanaka) é uma importante variedade comercial de citros no Brasil e o limão 'Cravo', seu principal porta-enxerto, apresenta suscetibilidade à gomose de Phytophthora, reduzindo a longevidade das plantas. Este experimento foi implantado em blocos ao acaso, contendo sete tratamentos, três plantas por parcela e quatro

15. Comportamento da laranjeira 'Pêra' sobre cinco porta-enxertos em ecossistema de tabuleiros costeiros, Umbaúba-SE
Em experimento instalado em 1984 no Campo Experimental de Umbaúba-SE, com delineamento em blocos casualizados, avaliou-se a potencialidade da laranjeira 'Pêra' [Citrus sinensis (L.) Osb.], clone D6, enxertada sobre cinco porta-enxertos. A análise estatística das médias dos dados do 9° ao 13° ano do plantio permite concluir que as seleções do limoeir

16. Distribuição do sistema radicular de porta-enxertos para lima ácida 'Tahiti'
Estudos sobre o sistema radicular são importantes para seleção de material genético e orientação de tratos culturais, como irrigação localizada, adubação e manejo de solo. O objetivo deste trabalho foi avaliar a distribuição do sistema radicular de seis porta-enxertos cítricos em um Latossolo Vermelho distroférrico no Norte do Paraná, levando

17. Variabilidade cromossÃmica e relaÃÃo entre espÃcies e cultivares de Citrus L
Foi realizada a anÃlise citogenÃtica em 32 acessos diplÃides, com 2n = 18, e dois triplÃides, com 2n = 27, de citros atravÃs da coloraÃÃo CMA/DAPI. Adicionalmente, foi realizada a hibridizaÃÃo in situ em cultivares de lima, limÃo, cidra e pomelo. A maioria dos cromossomos apresentou regiÃes heterocromÃticas principalmente nos telÃmeros dos braÃ

18. Sensitivity to Alternaria alternata toxin in citrus because of altered mitochondrial RNA processing
Specificity in the interaction between rough lemon (Citrus jambhiri Lush.) and the fungal pathogen Alternaria alternata rough lemon pathotype is determined by a host-selective toxin, ACR-toxin. Mitochondria from rough lemon are sensitive to ACR-toxin whereas mitochondria from resistant plants, including other citrus species, are resistant. We have identified

19. Purification of a Zn-binding phloem protein with sequence identity to chitin-binding proteins.
In citrus blight, a decline disorder of unknown etiology, the tree canopy exhibits symptoms of Zn deficiency while Zn accumulates in the trunk phloem. We have purified a Zn-binding protein (ZBP) from phloem tissue of healthy and blight-affected citrus (Citrus sinensis [L.] Osbeck on Citrus jambhiri [L.]). The molecular weight of the ZBP was estimated to be 5

20. Identity and Behavior of Xylem-Residing Bacteria in Rough Lemon Roots of Florida Citrus Trees †
An aseptic vacuum extraction technique was used to obtain xylem fluid from the roots of rough lemon (Citrus jambhiri Lush.) rootstock of Florida citrus trees. Bacteria were consistently isolated from vascular fluid of both healthy and young tree decline-affected trees. Thirteen genera of bacteria were found, the most frequently occurring genera being Pseudom

21. Host-Specific Effects of Toxin from the Rough Lemon Pathotype of Alternaria alternata on Mitochondria 1
Host-specific toxin from the rough lemon (Citrus jambhiri Lush) pathotype of Alternaria alternata (ACR toxin) was tested for effects on mitochondria isolated from several citrus species. The toxin caused uncoupling of oxidative phosphorylation and changes in membrane potential in mitochondria from leaves of the susceptible host (rough lemon); the effects dif

22. Evaluation of Polyamine and Proline Levels during Low Temperature Acclimation of Citrus 1
The polyamines (PA) putrescine (Put), spermidine (Spd), and spermine (Spm) were measured during 3 weeks exposure to cold hardening (15.6°C day and 4.4°C night) and nonhardening (32.2°C day and 21.1°C night) temperature regimes in three citrus cultivars: sour orange (SO) (Citrus aurantium L.), `valencia' (VAL) (Citrus sinensis L. Osbeck), and rough lemon

23. Processes Modulating Calcium Distribution in Citrus Leaves. An Investigation Using X-Ray Microanalysis with Strontium as a Tracer
Citrus leaves accumulate large amounts of calcium that must be compartmented effectively to prevent stomatal closure by extracellular Ca2+ and interference with Ca2+-based cell signaling pathways. Using x-ray microanalysis, the distribution of calcium between vacuoles in different cell types of leaves of rough lemon (Citrus jambhiri Lush.) was investigated.
