Citrus lab


Lab History

Citrus lab was created during the installation of the experimental groves and the collection of citrus varieties and rootstocks at 1972. In 1977, agronomist Mr. Eftyxios Protopapadakis was assigned to the Institute of Subtropical Plants, after his graduation on virology from the University of Bordeaux II, and in 1981 he obtained his PhD degree on Genetic Improvement and Citrus Taxonomy. After the retirement of Mr. E. Protopapadakis (2006), agronomist Ms V. Loxou was assigned as head lab. In 2007 Mr. N. Kavroulakis was assigned as head lab until September 2017.

At October 2017, the new citrus researcher Dr. Vasileios Ziogas was hired and placed in charge of the IOSVs lab of citriculture.

Subject

The Institute for Olive tree, Subtropical Plants and Viticulture (IOSV), established in Chania, apart from its research activity, is the curator of the National collection of Citrus plants, preserving a wide range of many citrus varieties and rootstocks. 

 The main research objectives of the lab of citriculture are:

  • Study of antioxidants and their intercellular mechanisms, as biologically active substances with functional role in nutrition and health
  • Evaluation and study of citrus varieties and rootstocks, in terms of qualitative characteristics and their adaptation to abiotic adverse conditions
  • Production and genetic determination of citrus plants, especially varieties and rootstocks acclimated to climate change and market oriented
  • Evaluation and study of agricultural systems adapting principals of precision agriculture and use of innovative technology in citrus orchards
  • Study and evaluation of pioneer compounds for their efficient use in tree crops, in terms of yield and fruit quality
  • Preservation, characterization and enrolment of new citrus species, varieties and rootstocks to the National and European list of citrus cultivars

In the lab of citruculture a series of fruit qualitative measurment are performed including:

Fruit weight, fruit diameter and axis, albedo and flavedo thickness, juice content, total sulible solids, resistance to penetration, skin color, juice color, total acidity, vitamin C (ascorbic acid) content, total phenols, total antioxidant activity.

Results
  • In IOSVs citrus lab, different citrus varieties and root stocks introduced from abroad, were evaluated for their potential adaptation to local microclimate conditions (Papadakis et al., 2008). Results indicated that the late varieties “Lane Late” and “Navel Late” when crafted upon Citrumelo and Volkameriana rootstocks, were more adaptive and produced fruits of superior quality, preserving them upon the tree until June.
  • Various vmandarin varieties were evaluated for their ripening period.  “Marisol” clementine and “Satsuma Wase” varieties were the most early ones, reaching their maturation stage in October, while the Nova hybrid, ripen from November and sustained superior quality characteristics until February.
  • Rootstock research showed that Sour orange Brazilian and Sour orange bitter sweet were more adaptive to salinity, while Citrange carizzo was more ideal for early citrus varieties, while Citrumelo Swingle was more suitable for late citrus varieties.
  • IOSVs Citrus lab, was the breeder of new varieties, which were created by using the method of nuclear plants. The Navel RO25 variety, is a creation of IOSV, and among the most early navel ones in Greece. It reaches maturation stage ten days earlier than the “New Hall” with round shaped fruits with thin rind. Zampetaki lemon variety was created by a nuclear plant from “Messara” lemon variety after free pollination with Eureka lemon variety. The fruits are seedless, and ripen mainly during summer.
