in acid soils, aluminium toxicity is the primary factor limiting crop and forage production. at soil ph < 5.0, al solubility increases and al appears to be rhizotoxic. the objectives of the present study were to compare al tolerance among wild graminae of acid meadows and to evaluate the relation between a plant functional trait and the al resistance, in nutrient solution. in addition, a sensit...
Previous studies have indicated that an increased asparagine to glutamine ratio (Asn : Gln) occurs in the xylem fluid of Lolium perenne 24 h after defoliation. However, the absolute changes in Asn and Gln leading to the increased Asn : Gln ratio are unknown. The present study tested the hypotheses that: (1) defoliation-induced changes in xylem amino acid composition occur in L perenne within th...
Nowadays, stress management is considered to be very important in landscapes. The present research was conducted to investigate the effects of regulated deficit irrigation at 4 levels (25, 50, 75 and 100% of lawn irrigation requirement) on some biochemical indices of four groundcover plants (Lolium perenne, Potentilla spp, Trifolium repens and Frankinia spp) to be used in landscapes, with 3 rep...
Lolium perenne is a freeze-tolerant perennial ryegrass capable of withstanding temperatures below -13 °C. Ice-binding proteins (IBPs) presumably help prevent damage associated with freezing by restricting the growth of ice crystals in the apoplast. We have investigated the expression, localization and in planta freezing protection capabilities of two L. perenne IBP isoforms, LpIRI2 and LpIRI3, ...
