... Seedlings of Citrus grandis (L.) Osbeck cv. Tuyou were irrigated daily for 5 months with nutrient solution containing 0 (control), 0.2, 0.6 or 1.6 mM aluminum (Al) from AlCl3·6H2O. Shoot growth was more sensitive to Al toxicity than root growth, gas exchange, chlorophyll (Chl) concentration, polyphasic Chl a fluorescence (OJIP) induction and related parameters. Leaves of Al-treated plants showed d ...
... A series of crosses designed for introgression of mandarin (Citrus reticulata Blanco) and pummelo (C. maxima Merr.) germplasm, to develop an alternative rootstock to sour orange (C. aurantium L.), were carried out. It is necessary to identify those hybrids that yield nucellar seedlings for rootstock propagation. Rootstocks can be developed through traditional plant breeding methods; however, the a ...
... Huanglongbing (HLB, yellow shoot disease, ex. citrus greening disease), caused by Candidatus Liberibacter spp., is highly destructive to citrus production in Asia, Africa, and South America. Although primarily affecting sweet orange and mandarin, HLB has long been observed in pummelo in Guangdong Province, People's Republic of China; however, the disease in pummelo has received little research att ...
... Grapefruit growers in the tropics require information about existing and new citrus cultivars with high productivity potential. The objective of this study was to determine the growth, yield, and fruit quality performance of seven pigmented and four white grapefruit cultivars under the dry tropic conditions of Colima, Mexico. The trees were budded on sour orange (Citrus aurantium L.) rootstock and ...

Abstract:
... Cross-pollination was performed with soft-X-irradiated hyuga-natsu pollens (1000Gy) for 'Tosa-Buntan' pummelo (Citrus grandis (L.) Osbeck). This resulted in the transformation of large and complete seeds into small and empty ones (practically seedless). Although fruit set, fruit retention, total soluble solids content (TSS) and titratable acidity of the juice were not affected, decrement in the fr ...
... A farmers' participatory survey was carried out in the mid-hill and plain (Terai) regions of Nepal to assess the diversity, consumers' preference for fruit quality and potential for selection of elite pomelo clones. A wide variation of morphological characters of tree, fruit, leaf and seed was identified from information gathered and from laboratory analysis. Multivariate analysis of the data prod ...
