Abstract: The paper presents the results of laboratory germination testing and morphological characteristics of sweet chestnut (Castanea sativa Mill.) seedlings. The research samples were collected in the sub-Mediterranean region of Croatia, and the working sample for germination testing was 8×25 seeds. Prior to germination testing, the seeds were stored in a refrigerator for three months at 3°C. The percentage of laboratory germination was established according to the percentage of regular seedlings which germinated normally after 27 days of testing. The testing was carried out in a laboratory under the conditions prescribed by ISTA (International Seed Testing Association). A digital photo camera was used to take photos of all abnormal seedlings, which were then catalogued with their pictures and descriptions. The results of this research are very useful for nursery practice and can be applied in producing plants from seeds, rootstocks for grafting, and further raising of seedlings to be grown in plantations.

From field to orchard: wild sweet chestnut populations and marron characteristics and adaptability to stress - HRZZ project

Acronym: CHESTNUT AND MARRON

Project Main Objectives

The main goal of this research is to reveal: (1) neutral and adaptive variability in sweet chestnut natural populations from different environmental habitats in Croatia; (2) associations between genetic structure, morphological variation, chemical variation and environmental differences (climatic and soil) in sweet chestnut natural populations; (3) sweet chestnut seed quality and germination requirements; (4) genetic basis of variation for adaptive traits on seedlings reared in greenhouse; (5) genetic basis of variation for adaptive traits on seedlings reared in reciprocal transplant experiments; (6) epigenetic responses to drought stress; (7) tolerance of selected genotypes to pathogens; (8) resistance to pathogens on seedlings reared in nursery; (9) associations between population genetic approach and greenhouse and reciprocal transplant experiments; (10) continuation of long term monitoring of C. parasitica populations; (11) neutral and adaptive variability in Croatian sweet chestnut cultivars; (12) differences in fruit and leaf morphology and chemical composition of fruits between Croatian chestnut cultivars; (13) associations between genetic, morphological variation, chemical variation and environmental differences (climatic and soil) in chestnut cultivars; (14) delineation of seed zones and definition of seed transfer guidelines for Croatian chestnut populations.

Aside from contribution to the basic scientific knowledge on molecular biology and ecology of sweet chestnut, the results of this project will contribute to the development of sustainable management of sweet chestnut in Croatia. Based on the results from this research, we will delineate seed zones and define seed transfer guidelines, which will provide operational, effective criteria, methods, guidelines, and recommendations helping in the optimal management of Croatian sweet chestnut stands. Furthermore, from Croatian natural sweet chestnut populations, genotypes tolerant to abiotic stress, i.e. drought, will be selected. The genotypes with higher tolerance to biotic stress, i.e. infection with C. parasitica, will be selected as well. Additionally, results from this project will contribute directly to the protection of geographic origin of the autochthonous marron cultivars, which is very important for the local population in the Lovran area, Istria and island Cres, but for Croatia as well
