Abstract Background and aims The pasture legume Trifolium subterraneum ssp. yanninicum exhibits waterlogging tolerance. This study investigates diversity for tolerance within . We tested the hypotheses that (1) variation exists (2) is related to phenotypic growth trait differences, which (3) reflect eco-geographic variables at site of origin. Methods Twenty-eight diverse ecotypes collected from...

When petioles of transpiring leaves are cut in the air, according to the 'Scholander assumption', the vessels cut open should fill with air as the water is drained away by tissue rehydration and/or continued transpiration. The distribution of air-filled vessels versus distance from the cut surface should match the distribution of lengths of 'open vessels', i.e. vessels cut open when the leaf is...

Agricultural bioinoculants containing arbuscular mycorrhizal fungi represent a potential opportunity to reduce the dependence of grapevines ( Vitis ) on agrochemicals. This field study assessed ability four commercial colonize grapevine roots and their effects petiole nutrient concentration, berry composition, root morphology ‘Pinot noir’ vinifera grafted onto rootstock ‘Couderc 3309’ riparia ×...

Petiole growth in Thlaspi arvense L. was stimulated when a basic 8 hour photoperiod (4.20 milliwatts per square centimeter) was extended with low intensity light (0.16 milliwatt per square centimeter) from incandescent lamps. The day length extension was effective only when the light contained high proportions of far red light. Exogenous gibberellin A3 (GA3) could partially substitute for the p...

urtica dioica l. is an iranian native pharmacological plant for which little attention has been paid to the anatomical structure. medical applications of this plant include diabetes therapy, digestive improvement, anemia and kidney disease therapy. because climatic conditions can affect the anatomical structure which in turn affects pharmacological compositions, research on the anatomy of this ...

There are two optima for maximizing hydraulic conductance per vasculature volume in plants. Murray's law (ML) predicts the optimal conduit taper for a fixed change in conduit number across branch ranks. The opposite, the Yarrum optimum (YO), predicts the optimal change in conduit number for a fixed taper. We derived the solution for YO and then evaluated compliance with both optima within the x...
