Flowering phenology of olives in Lun

Lunjske masline predstavljaju jedinstveni botanički park različitih genotipova maslina. Na površini veličine cca 400 ha rasprostire se više tisuća stabala masline nejednake starosti i različitih genetsko-morfoloških karakteristika. Uspješnost cvatnje i oplodnje preduvjet je za kvalitetan urod maslina. Naglašene klimatske promijene u zadnjih nekoliko godina značajno utječu na vrijeme pojave i trajanje fenofaze cvatnje. Od elemenata klime na cvatnju mogu utjecati: temperaturni ekstremi, sume aktivnih i inaktivnih temperatura, vjetar, vlaga zraka i tla. Stoga je bitno svake godine zabilježbom pratiti rokove pojave i trajanje fenofaze cvatnje. Tema ovog rada je zabilježbom pratiti u 2020. godini pojavu, trajanje i kraj cvatnje na 10 fenotipova maslina u kompleksu maslinika Lunjskih maslina. Odabrana stabla nalaze se na različitim mikrolokacijama imenovanog kompleksa. U radu je zaključeno da postoji značajna razlika u vremenu cvatnje između nekih genotipova lunjskih maslina. Kod genotipova maslina 2, 3, 4, 6 i 9 nema razlike u početku i trajanju podfenofaza fenofaze cvatnje. Kod genotipa masline 1 fenofaza cvatnja je krenula najranije, a kod genotipa maslina 5 i 10 fenofaza cvatnje je krenula najkasnije. Genotip masline 8 je 4 dana kasnio za genotipovima masline 2, 3, 4, 6 i 9. Genotip masline 7 je 7 dana kasnio za genotipovima masline 2, 3, 4, 6 i 9. Početak cvatnje je najranije zabilježen 19. svibnja, a najkasnije 1. lipnja.Olives from Lun are a unique botanical park of different olive genotypes. On an area of approximately 400 ha, there are several thousand olive trees of unequal age and different genetic and morphological characteristics. Successful flowering and fertilization is a precondition for a quality olive crop. Emphasized climate change in the last few years significantly affects the time of occurrence and duration of the flowering phenophase. Of the climate elements, flowering can be influenced by: temperature extremes, sums of active and inactive temperatures, wind, air and soil humidity. Therefore, it is important to monitor the timing and duration of the flowering phenophase every year. The topic of this paper is to monitor the occurrence, duration and end of flowering in 10 olive phenotypes in the olive grove complex of Lun in 2020. Selected trees are located at different microlocations of the named complex. The paper concluded that there is a significant difference in flowering time between some olive genotypes in Lun. In olive genotypes 2, 3, 4, 6 and 9 there is no difference in the beginning and duration of the subphenophases of the flowering phenophase. In the case of genotype 1, the phenophase of flowering started at the earliest, and in the case of genotypes olive 5 and 10, the phenophase of flowering started at the latest. The olive genotype 8 was 4 days late opposed the olive genotypes 2, 3, 4, 6 and 9. The olive genotype 7 was 7 days late opposed the olive genotypes 2, 3, 4, 6 and 9. The beginning of flowering was recorded on 19 May at the earliest, and June 1st at the latest
