Abstract

The study of vegetative propagation of the Vitex agnus-castus L., was conducted in the Agriculture College - Salahaddin University field under controlled condition (plastic greenhouse) in two periods (summer time: from 26.5.2008 to 2.9.2008 and winter time: from 15.1.2009 to 28.4.2009). The object of the studies were different soil substrates (sand and river (sharp) sand - sand and peat moss - sand and river (sharp) sand and peat moss). We used two types of stem cuttings (semi-hardwood cuttings „m“ - softwood cuttings „a“). The statistical analysis is based on the experimental project Complete Randomized Design (CRD) with three replications. The results were compared with results from Duncan test at 0.05 level. The study showed that planting in the second period (T2) causes increase in number of branches and leaves, whereas planting in the first period (T1) causes increase in number of roots and root length, the increase in the weight of biomass and dry mass has been observed in the second period of planting (T2). Planting in the sand substrate using semi-hardwood cuttings (m) causes increase in number of branches, leaves, fresh weight, number of roots and root length

Súhrn

Výskum vegetatívneho rozmnožovania Vitex agnus-castus L. bol realizovaný na výskumných plochách Poľnohospodárskeho inštitútu Univerzity Salahaddin, v kontrolovaných podmienkach (fóliovník) v dvoch sledovaných obdobiach (letné obdobie: 26. 5. 2008 - 2. 9. 2008 a zimné obdobie: 15. 1. 2009 - 28. 4. 2009). Skúmaný bol vplyv rôznych pôdnych substrátov (piesok - piesok; riečny piesok - piesok; rašelina - piesok; riečny piesok a rašelina). Použili sme dva druhy stonkových odrezkov (odrezky z polotvrdého dreva „m“; odrezky z mäkkého dreva „a“). Štatistická analýza vychádza z experimentálneho projektu (Complete Randomized Design CRD) s tromi opakovaniami. Výsledky získané prostredníctvom CRD boli následne porovnané s výsledkami získanými Duncanovým testom na úrovni 0,05. Výskumom sme dokázali, že výsadba v druhom sledovanom období (T2) vykazuje nárast počtu vetiev a počtu listov, kým výsadby v prvom sledovanom období (T1) vykazujú zvýšenie počtu a dĺžky koreňov a výsadby v druhom sledovanom období (T2) vykazujú zvýšenie hmotnosti biomasy, ako aj hmotnosti sušiny. Výsadba do pieskových substrátov za použitia odrezkov z polotvrdého dreva (m) spôsobuje nárast počtu vetiev, listov a koreňov, zvýšenie čerstvej váhy a predĺženie koreňov.
