1. Response of grey slug to entomopathogenic nematodes
ABSTRACT Biological control using entomopathogenic nematodes (EPNs) is known as an ecofriendly strategy in integrated pest management. The terrestrial slug Parmacella ibera is a major pest of vegetables and citrus trees in north of Iran. The heavy costs and environmental concerns of synthetic molluscicides led the study to use EPNs, against the slug P. ibera

3. Morphophysiology of Tahiti lime grafted onto Sunki mandarin hybrids under salt stress
RESUMO Objetivou-se avaliar o crescimento e a fisiologia de combinações copa/porta-enxertos de citros irrigados com água salina até a fase de pré-floração. O experimento foi realizado em lisímetros de drenagem com capacidade de 150 dm3, em delineamento de blocos casualizados em esquema fatorial 2 x 10, correspondendo a duas condutividades elétricas

4. Potential of Pinus elliottii Engelm. needles as substrate conditioner for the production of “Fepagro C37 reck”Citrus rootstocks”
Resumo A produção de mudas de citros em ambiente protegido demanda grande quantidade de substrato, o qual deve apresentar características físicas e químicas adequadas. O uso de condicionadores ácidos, como acículas de Pinus, em mistura com substratos alcalinos, possibilita o cultivo de mudas com maior qualidade. O objetivo foi avaliar o desenvolvimen

5. Interactions of adjuvants on adhesion and germination of Isaria fumosorosea on adults of Diaphorina citri
ABSTRACT: Asian citrus psyllid, Diaphorina citri, is considered the most important citrus pest worldwide, as it transmits Huanglongbing – serious citrus disease. New efficient and sustainable strategies to control this pest have been investigated and the use of entomopathogenic fungi has become a promising alternative. The objective of this study was to ev

6. Translocation and Root Exudation of Glyphosate by Urochloa brizantha and its Transport on Sugarcane and Citrus Seedlings
RESUMO: O glyphosate é facilmente exsudado pelas raízes das plantas. No entanto, ainda falta informação na literatura científica sobre a braquiária (Urochloa brizantha) é capaz de exsudar o glyphosate a ponto de influenciar o crescimento de culturas, como cana-de-açúcar e citros. Assim, o objetivo desta pesquisa foi avaliar a translocação e exsuda

7. Vigor and mortality of citrus progenies with potential use as rootstocks
ABSTRACT: Rootstocks influence certain characteristics of the scion, such as vigor, fruit yield and quality, and tolerance to biotic and abiotic factors. In conventional citrus breeding programs, hybridization is the main method used for obtaining rootstock varieties. Between Sept and Oct 2006, controlled pollinations were carried out resulting in nine proge

8. Water deficit increases the frequency of hybrid citrus with polyembryonic female parents
Abstract The aim of this study was to develop a methodology that uses water deficit induction to increase the frequency of hybrids in Citrus varieties that have a high and an intermediate level of polyembryony, respectively. The experiment examined the ‘Sunki Tropical’ mandarin and ‘Rangpur Santa Cruz’ lime genotypes at three water stress intensities

9. CONDICIONES DE CULTIVO DE LA PLANTA MATRIZ Y USO DEL ÁCIDO INDOLBUTÍRICO EN LA PROPAGACIÓN DEL MANDARINO ‘SUNKI’ BAJO ESTAQUILLA
ABSTRACT Citrus rootstocks are obtained from seeds, selecting the apomitic seedlings. However, there is risk of not making the correct selection, due to low level of polyembryony and high heterozygosity in some species or cultivars, such as ‘Sunki’ mandarin. Therefore, obtaining the citrus rootstocks through cuttings may solve the problem. The objective

10. Method to evaluate the efficiency of manual overhead irrigation in citrus rootstock liner production
ABSTRACT Brazil produces grafted citrus seedlings in closed screen houses to reduce pest and disease incidence. Irrigation is usually performed by hand using either breaker nozzles or drilled polyvinyl chloride (PVC) pipe wands on garden hoses. Rootstocks are produced in cone-shaped containers filled with soilless potting mix. Since the containers have a sma

11. Cultura de anteras e partenogênese in situ e in vitro de genótipos de laranja doce (Citrus sinensis Osbeck.) / Anther culture and in vitro and in situ parthenogenesis of sweet orange (Citrus sinensis Osbeck.) genotypes
The production of completely homozygous lines in citrus breeding program is hard, and double-haploid plantlets (completely homozygous lines) can be used to improve these breeding programs. However, many factors are associated with the success of the regeneration of haploid or double-haploid plants. The aim of this study was the induction and regeneration of

12. Desinfestação de substratos e fungos micorrízicos na produção de porta-enxertos de citros / Substrates and mycorrhizal fungi in the production of citrus rootstocks
The Brazilian citrus industry is one of the most competitive sectors of the agribusiness world, however, the production sector of citrus seedlings has several limitations. The citrus production rootstocks lacks quality of substrates, options for diversification of rootstock varieties and plants well-formed in a short time to reach success of the orchard. The
