The challenge facing raspberry production on a regular basis is knowledge of both the biology of growth and development and the characteristics of aboveground growth –pseudostems arising from the rhizome of raspberry, as dependent on the nature and position of adventitious buds from which they develop. In terms of the formation and realization of the bearing potential, fruiting canes as aboveground growth are classified according to the rooting degree of the supporting rhizome. The two-year research on the bearing potential of cv. ‘Polka’ as dependent on the type of aboveground growth indicates differences that are likely to affect the cost-effectiveness of raspberry production. The aboveground growth developing from primary adventitious buds positioned on horizontally growing roots exhibits significantly higher bearing potential compared to that arising from lateral buds positioned on etiolated belowground growth. The number of fruits per cane ranged from 310.20 to 429.15. Fruit characteristics were significantly affected by harvest date

Koncentracija Ca, P I Mg u serumu kod krava simentalske rase sa različitih geografskih područja

The aim of this paper is to examine the concentration Ca, P and Mg in serum of Simmental cows from different geographic areas (lowland and mountain). Total number of animals tested was 42 healthy cows, by 21 at each farm, aged 3-5 years. The researches were carried out in two periods: autumn-winter (November-December 2008), and repeated in spring (April-May 2009) on the same cows. The concentration of Ca, P and Mg in the blood (serum) from both locations was significantly higher in spring than in winter, but do not exceed the physiological value.Cilj ovog rada je da se ispita koncetracija Ca, P i Mg u serumu kod krava simentalske rase sa različitih geografskih područja (ravničarsko i planinsko). Ukupna broj ispitivanih životinja je 42 zdrave krave, po 21 na svakoj farmi, starosti 3-5 godina. Istraživanja su provedena u dva perioda: jesen-zima (novembar-decembar 2008), te ponovljena na istim kravam u proljeće (april-maj 2009). Koncentracija Ca, P i Mg u krvi (serumu) sa oba lokaliteta je značajno viša u proljeće nego u zimu, ali ne prelazi fiziološke vrijednosti
