Abstract: Until 2007, there were no data on the presence of Rosa micrantha Borrer ex Sm. inMoldova, most of the authors considering these species as unreported from this historical province of Romania.Researches between 2009 – 2011 led to the identification of 5 locations in Bacău, Neamţ and Suceava counties.
Keywords: Rosa micrantha, chorology, Moldova, Romania.
Introduction
According to Klášterský, the Rosa L. genus is reprezented in Europe by 47species [8]. Depending on the adopted aproach, in Romania are growing 19 to 29species. Beldie (1977) mentions 19 spontaneous species of Rosa genus [2]; in “Flora R.P. R.” (1956) are described 25 species [3]; Ciocârlan (1988) considers 22 species, but in2000 and 2009, the same author describes 23 to 27 species (depending on the approachof Rosa canina L.) [5, 6, 7]; Klášterský, in 1968, and Oprea (2005) mentioned 29spontaneous and subspontaneous species [8, 10]. From those 29 species, only 16 wereidentified in the northeastern part of Romania [10].
Materials and methods
Researches took place during 2009 – 2011, in may – june (blossom period) andlate september – october (at the fully ripe stage of the fruits). Fruit width (mm) andlength (mm) measurements were done on 100 fruits for each genotype. Samples of eachgenotype were herborized and can be found in the Herbarium of the Alexandru IoanCuza University.
For the identification of specimens we used Flora R. P. R., vol. IV (1956);Flora Europaea, vol. II (1968); Flora României, vol. I (Beldie Al., 1977); Florailustrată a României, vol. I (Ciocârlan V., 1988); Flora lemnoasă spontană şi cultivatădin România, vol. II (Zanoschi et al., 2000); Flora ilustrată a României (Ciocârlan V.,2000, 2009); Flora ilustrată a plantelor vasculare din estul României, vol. I (Sârbu I. etal., 2001) [2, 3, 5, 6, 7, 8, 12, 14].
Results and discussions
Rosa micrantha Borrer ex Sm. is a shrub, up to 3 – 5 m high. Leaflets areusually rounded at base; pedicels stipitate – glandular; sepals glandular; fruit glabrous orglandular – hispid [8]. Blossom period: june. The fruit is globose or ellipsoid. Averagefruit diameter is 0,872 cm – 0,972 cm, and the average lenght between 1,444 cm and1,600 cm (we examined 7 genotypes, from 5 locations).
This species belong to the Rosa rubiginosa group, from the Caninae DC.section [8]. It has been recorded from Western, Southern and Central Europe, extendingto the North Ukraine, South Russia, Crimea, Caucasus, Armenia, Lebanon, Turkey andNorth West Africa [8, 13]. It develops in open woodland and forests edges, bushes. Itgrows on a range of well-drained soils, rather on calcareous substrate, on skeletal, weakacid-neoutrophilous soils [2, 12].
Figure 1. Distribution of Rosa micrantha in Moldova (Romania)
Within Romanian flora, Rosa micrantha is considered as sporadical, fromplains up to mountains [2, 5, 6, 7, 10], or common [3]. According to the literature before2007, this species was unreported from Moldova [2, 3, 4, 10, 14]. According to the RedList of Superior Plants of Romania [9], it is a rare species, but not threatned [10]. Firstmention for this area appeared in 2007 [1], in a floristic list from Bistriţa River basin,between Piatra Neamţ and Bacău towns. Then, in 2009 we found this species at Vama,Suceava County (470 34' 31" N, 250 41' 41" E, altitude 588 m) [11]. Researches from theperiod 2010 – 2011 led to the identification of two new locations in Suceava county(Suceviţa - 470 46' 54" N, 250 42' 29" E, altitude 595 m and Dorna Candreni - 470 21' 21"N, 250 17' 02" E, altitude 850 m), one new location in Neamţ county (Bicaz Chei - 460
49' 24" N, 250 50' 57" E, altitude 668 m) and to the confirmation of this species in Bacău
89
county close to the Lespezi locality (between Lespezi and Racova - 460 40' 25" N, 260
44' 54" E, altitude 200 m) (Fig. 1).
Conclusions
As a result of those studies, Rosa micrantha can be considered as sporadical inthe Romanian flora, but the area of distribution is still poorly known. In the northeasternpart of Romania, R. micrantha has a relativelly wide altitudinal amplitude, between 200m (Bacău county) and 850 m (Suceava county).
