Potpuno su promrzle i uginule: Nerium oleander (u jesen posađene reznice), Parkinsonia aculeata (jednogodišnje biljke, nezaštićene), Ricinus communis, Rosmarinus officinalis (u jesen posađene reznice) i Schinus molle. Potpuno su promrzli pojedini primjerci sljedećih vrsta: Bougainvillea spectabilis, Brachychiton populneum, Casuariana equisetifolia, Poenix canariensis, Prunus laurocerasus i Pyracantha coccinea (u jesen posađene reznice). Promrzao je samo nadzemni dio kod: Accacia cyanophylla, Citrus sp., Ceratonia siliqua, Cistus vülosus i C. salviaefolius, neki eukalipti (E. camaldulensis, E. globulus i E. viminalis), Mimosa Thompsoni, Nerium oleander (kbd većine grmova) i Teucrium fruticans. Kod ostalih navedenih vrsta stradalo je samo lišće u većoj ili manjoj mjeri. Kod alepskog bora na nižim nadmorskim visinama iglice su samo promijenile normalno zelenu boju u blijedo sivozelenkastu, dok je na višim položajima bilo i sušenja te otpadanja iglica. Iako je početkom proljeća izgled dendroflore bio dosta loš, tokom ljeta i jače oštećeni primjerci potpuno su se regenerirali, pa se može reći, da, prema dosadnjim opažanjima, ova izvanredna zima nije nanijela dendroflori u Splitu i njegovoj okolici znatnije štete.

SUMMARY The authors describe the effect of the 1955/56 cold winter period upon the trees and bushes in Split and its surroundings. In 1955´56 there was in general an extraordinary cold winter, in the Adriatic area too, including Split and its surroundings. The singularity of that winter manifested itself in a rather high temperature in January and in two folloving cold periods. The first period of very low temperature took place about the end of January and in the first half of February. The second one during the first half of March. Despite the fact that it suddenly became cold, the monthly mean temperature was higher than the average temperature of the preceding years (8.2° C in January against 7.2" C). The cold period started on 26th January. Its characteristic has not been an extremely low absolute minimum (in sheltered places it made out —5.8° C while the result of 22 years observation showed —11.5° C absolute minimum temperature), but a long duration. Namely, the dayly temperature of the air in sheltered places has remained under 0° C for more than 20 days, and at 5 cm above the ground even 24 days (graf. 1). The under 0° C air temperature lasted 3 days in March while 5 cm above the ground 8 days (from 9th—16th of March). At the same time with the low temperature there was a cold north bora, with the |
