Citrus Reticulata Blanco

Considering the huge economic loss caused by postharvest diseases, the identification and prevention of citrus postharvest diseases is vital to the citrus industry. In 2018, 16 decayed citrus fruit from four citrus varieties—Satsuma mandarin (Citrus unshiu), Ponkan (Citrus reticulata Blanco cv. Ponkan), Nanfeng mandarin (Citrus reticulata cv. nanfengmiju), and Sugar orange (Citrus reticulata Blanco)—showing soft rot and sogginess on their surfaces and covered with white mycelia were collected from storage rooms in seven provinces. The pathogens were isolated and the pathogenicity of the isolates was tested. The fungal strains were identified as Lasiodiplodia pseudotheobromae based on their morphological characteristics and phylogenetic analyses using the internal transcribed spacer regions (ITS), translation elongation factor 1-α gene (TEF), and beta-tubulin (TUB) gene sequences. The strains could infect wounded citrus fruit and cause decay within two days post inoculation, but could not infect unwounded fruit. To our knowledge, this is the first report of citrus fruit decay caused by L. pseudotheobromae in China.

Ponkan Mandarin

RAPD analysis of 19 Ponkan mandarin accessions was performed using 25 random primers. Of 112 amplification products selected, only 32 were polymorphic across five accessions. The absence of genetic variability among the other 14 accessions suggested that they were either clonal propagations with different local names, or that they had undetectable genetic variability, such as point mutations which cannot be detected by RAPD.

O trabalho foi desenvolvido com o objetivo de avaliar o efeito do acúmulo de temperaturas abaixo de 20° C, sobre a floração de tangerineiras 'Ponkan' (Citrus reticulata Blanco). Foi adotado o delineamento inteiramente casualizado, com seis tratamentos e quatro repetições. Os tratamentos foram formados por sete datas de transferência das mudas, mantidas a céu aberto, para a câmara de crescimento. Foram utilizadas plantas de tangerineira 'Ponkan' enxertadas sobre limoeiro 'Cravo', cultivadas em recipientes, que inicialmente foram mantidas a céu aberto. O experimento foi iniciado no dia 16-05-2007 (início do período de redução da temperatura na região) e conduzido até 17-08-2005. Quinzenalmente, quatro plantas que estavam a céu aberto foram transferidas para câmara de crescimento, com temperaturas de 27°C/20°C (dia/noite), umidade relativa de 75%, fotoperíodo de 12 horas e radiação fotossinteticamente ativa de 170 µmol m-2 s-1. Foram avaliados a data do florescimento e o número total de flores de todas as plantas. Quanto maior foi o tempo de permanência das plantas a céu aberto em temperaturas inferiores a 20° C, maiores foram a antecipação do florescimento e o número de flores produzidas.
