Meiosis in the leek (Allium porrum L.) revisited I. Prophase I pairing
Chromosome Research, 1995Meiotic chromosome pairing of the tetraploid species Allium porrum, the cultivated leek, was analysed by electron microscopy of 83 surface-spread nuclei in the late zygotene to early diplotene interval of prophase I, from four different varieties. Prophase I quadrivalent frequency, at 71%, marginally but significantly exceeds the two-thirds expected on

Polygalacturonase activity and location in arbuscular mycorrhizal roots of Allium porrum L.
Mycorrhiza, 1995Polygalacturonase activity and location were analysed in leek roots (Allium porrum L.) colonized by Glomus versiforme (Karst.) Berch, an arbuscular mycorrhizal (AM) fungus. Polygalacturonase activity in mycorrhizal roots did not differ quantitatively from that found in nonmycorrhizal roots on all of the four harvesting dates.

Leek (Allium porrum L.) seed development and germination
Seed Science Research, 1992AbstractThe effects of development of leek seeds at 20/10°, 25/15° and 30/20°C (day/night) and drying of seed harvested at different developmental stages on subsequent performance were examined in each of 3 years. An increase in temperature from 20/10° to 30/20°C reduced mean seed weight from 2.90 to 2.55 mg as a result of a reduction in the duration ...

ODREĐIVANJE TEŠKIH METALA U PORILUKU (Allium porrum L.)
2017U ovom završnom radu su određene koncentracije odabranih teških metala u poriluku (Allium porrum L.) koji je sabran u travnju 2017. godine. Poriluk je podijeljen na dvije frakcije: nadzemni dio i podzemni dio. Koncentracije odabranih teških metala su određene elektroanalitičkim metodama. Uočava se kako se veći dio teških metala, cinka, kadmija, olova i
