Salinity Effects on Water Potential Components and Bulk Elastic Modulus of Alternanthera philoxeroides (Mart.) Griseb.

Salinity Effects on Water Potential Components and Bulk Elastic Modulus of Alternanthera philoxeroides (Mart.) Griseb.

Pressure volume curves for Alternanthera philoxeroides (Mart.) Griseb. (alligator weed) grown in 0 to 400 millimolar NaCl were used to determine water potential (Psi), osmotic potential (psi(s)), turgor potential (psi(p)) and the bulk elastic modulus (epsilon) of shoots at different tissue water contents. Values of psi(s) decreased with increasing salinity and tissue Psi was always lower than r...

Salinity Effects on Photosynthesis and Growth in Alternanthera philoxeroides (Mart.) Griseb.

Alternanthera philoxeroides, alligator weed, was grown at five different NaCl concentrations to determine the effect of salinity on factors related to the net rate of CO(2) uptake (P(n)). Over the range of 0 to 400 millimolar NaCl, P(n) declined 51%. Stomatal conductance declined in parallel with P(n) and as a result there was no reduction in intercellular CO(2) concentration and therefore no r...

Assessing vegetative growth potential of exotic Rotala rotundifolia (Roxb.) Koehne (roundleaf toothcup), in comparison with Alternanthera philoxeroides (Mart.) Griseb. (alligator weed), a known successful invader

Invasion of alligator weed (Alternanthera philoxeroides) in Wular Lake, Kashmir, India

Alligator weed Alternanthera philoxeroides (Mart.) Griseb (Amaranthaceae) is being reported for the first time from Kashmir, India. Alternanthera philoxeroides was collected in 2008 during the vegetation survey of Wular Lake, a wetland of international importance under Ramsar convention. Alternanthera philoxeroides is a noxious invasive weed widespread throughout the world. We suggested that al...

effect of seed priming and irrigation regimes on yield,yield components and quality of safflowers cultivars

این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
