Abstract

Bajam je lupinasta voćna vrsta čiji plodovi imaju široku primjenu u prehrambenoj, farmaceutskoj i kozmetičkoj industriji. U Hrvatskoj se uglavnom uzgaja na području s mediteranskom klimom, a rodnost uveliko ovisi o agroekološkim uvjetima uzgoja.
Problem kod uzgoja bajama je njegova rana cvatnja (siječanj, veljača), nakon čega vrlo često dolazi do pojave mrazova koji mogu uništiti cvijet te tako onemogućiti razvoj plodova i u konačnici smanjiti prinos. Cilj ovog istraživanja bio je utvrditi fenologiju cvatnje triju sorata bajama: 'Ferragnese', 'Troito' i 'Tuono' uzgajanih u nasadu bajama na području Ravnih Kotara kao i samoniklih genotipova koja rastu u okolici nasada. Uz praćenje datuma početka cvatnje, pune cvatnje i završetka cvatnje utvrđen je i broj rodnih izbojka, kao i broj cvjetova po rodnom izbojku te su na temelju UPOV-a deskriptora opisani cvjetovi bajama. Sorta 'Tuono' najranije je započela s cvatnjom (04. ožujka), dva dana kasnije sorta 'Troito', kao i samonikli genotipovi II i III, dok je sorta 'Ferragnese' najkasnije započela s cvatnjom (08. ožujka). Rezultati istraživanja ukazuju na razlike u početku i vremenu trajanja cvatnje, kao i broju cvjetova po rodnom izbojku.

Abstract (english)

Almond is a fruit-tree species whose fruits are widely used in the food, pharmaceutical and cosmetic industries. In Croatia, it is mainly grown in the areas with Mediterranean climate, with production being largely dependent on agro-ecological growing conditions.
The problem with almond cultivation is its early flowering (January, February), after which frosts often occur which can destroy the flower and thus prevent the development of the fruit and ultimately reduce the yield. The aim of this study was to determine the phenology of flowering of three almond cultivars 'Ferragnese', 'Troito' and 'Tuono' grown in a plantation in the area of Ravni kotari, as well as wild genotypes growing in the vicinity. In addition to monitoring the date of the start of flowering, full flowering and the end of flowering, the number of bearing shoots as well as the number of flowers per shoot were determined. The almond flowers were described based on the UPOV descriptor. The 'Tuono' variety started flowering at the earliest (March 4th), two days later the 'Troito' cultivar, as well as the wild genotypes II and III, while the cultivar 'Ferragnese' began to bloom at the latest (March 8th). The results of the study indicate differences in the onset and duration of flowering, as well as the number of flowers per bearing shoots.
