Abstract
A new and distinct variety of lemon named ‘Glueck’ characterized by producing mature fruit with a juice having a lemon flavor and a high sugar-acid ratio.
Description
Latin name of the genus and species of the plant claimed: Citrus limon.
Varietal denomination: ‘Glueck’.
The present invention refers to a new variety of lemon which will hereinafter be denominated as the ‘Glueck’ lemon tree. The ‘Glueck’ lemon tree produces lemon fruit that taste like lemon, but have juice with a high sugar-acid ratio, producing a lemon flavor without the sourness associated with lemon juice.
The invention (variety) comprises a new and distinct variety of a lemon tree discovered by the inventors in a cultivated orchard on the Finca Los Pocitos property in the Tucumán province of Argentina, which was purchased in 1993, and subsequently continuously owned, by the Applicant. Specifically, while working on the Finca Los Pocitos property, the inventors discovered the new cultivar and scion buds were removed from the identified trees for grafting onto Troyer citrange “Troy” rootstock (unpatented), which is a hybrid of Citrus sinensis and Poncirus trifoliate, to form a second generation. The new cultivar is believed to a spontaneous mutation of a lemon tree grown in the cultivated orchard. From the second generation, trees were selected on the basis of fruit superiority and growth parameters and scion buds were removed from the selected trees for further asexual reproduction by grafting to form a third generation. The new cultivar was subsequently asexually reproduced by the inventors in the Tucumán province of Argentina by grafting on a variety of root stocks, including Citrumelo Swingle CPB 4475 (Poncirus trifoliata x Citrus paradisi), Citrange C-35 (Citrus sinensis ‘Ruby’ orange x X Citroncirus webberii ‘Webber-Fawcett’ trifoliata), and 79 AC (Citrus reshni Hort. ex Tan. x Citrus paradisi Macf. x Poncirus trifoliata (L.) Raf.). This year the new cultivar was also grafted on Poncirus trifoliata ‘Rubidoux’ and Flying Dragon (Poncirus trifoliata var. ‘Monstrosa’) root stock. The inventors carefully compared all of the asexually reproduced trees with the originally discovered trees and found the fruit to be substantially identical in all distinctive respects through several generations of asexual reproduction including on different root stocks. The discovered cultivar has been shown to remain true to type in successive generations of such asexual reproductions.
In comparison with conventional lemon trees, the fruit of the present variety has a higher sugar-acid ratio, resulting in a fruit having a juice with a lemon flavor but lacking the sour acidity associated with typical lemon fruits.
The ‘Glueck’ lemon tree is particularly characterized by producing fruit with a high sugar-acid ratio, with a fall of fruits in December, with good fruit size.
It should be noted that the described characteristics may vary depending on agricultural practices and climatic conditions, location and season. The quantitative values set forth below are expressed as an average value, which is obtained from the specimens analyzed. Quantitative traits were taken from each of four specimen trees. The angles of divergence of the fruit branches with respect to the main axis were calculated by means of scale photographs.
Twenty fully developed leaves were selected from each specimen, considering the fifth leaf from the apex in orientation N, S, E, W and in good phytosanitary conditions. They were measured and photographed with a digital camera to calculate quantitative data. To determine the venation, size, and density of essential oil glands, the diaphanization and clarification technique was performed according to C. Dizeo de Strittmatter, “Nueva técnica de diafanización,” Bol. Soc. Arg. Bot. 15, 126-129 (1973) and later stained with 1% cresyl violet, as per G. E. Zarlaysky, “Histologia vegetal: técnicas simples y complejas,” 1a ed. Sociedad Argentina de Botánica, Buenos Aires (2014).
Ten flower buds were taken from each specimen in development stage medium and ten flowers in were taken in maturity stage (open corolla). These were measured and photographed to calculate quantitative values.
All observations of fruits and their parts were made at the optimum maturity stage. The characteristics described below correspond to the average of ten fruits and their respective seeds of each specimen.
Quantitative values were calculated directly through the use of calibrated measuring tape (TJIMA 30 m) and vernier caliper using scale photographs (made with a KODAK digital camera Az-252 16 mpx). Micromorphological values, surfaces, and angles were calculated using a Zeiss Stemi-2000C stereo microscope with a Zeiss Axiocam ERc 5s digital camera attached and AxioVision software version 4.8.2 (Carl Zeiss Ltd, Herts, UK). All values are expressed as mean values and standard deviation.
The descriptions of foliar traits and shapes were made following B. D. Ellis, C. Daly, L. J. Hickey, H. R. Johnson, J. D. Mitchell, P. Wilf, S. L. Wing, “Manual of leaf architecture,” Cornell University Press, USA (2009)
The colors are described in reference to The 2005 Royal Horticultural Society mini color chart.
The determination of sugars and acidity in juice was carried out in concentrated juice (10 mL) for each specimen by titration with 0.1 N sodium hydroxide and 1% phenolphthalein. The specifications by the Department of Primary Industries and Regional Development Agriculture and Food of the Government of Australia were followed.
The titration was monitored by color change and pH change up to 8.2-8.4.
