Growth and Physiological Performance of a Coastal Species Trifolium fragiferum as Affected by a Coexistence with Trifolium repens, NaCl Treatment and…
2021
The aim of the present study was to analyze the growth and physiological performance of two coexisting species, Trifolium fragiferum, and Trifolium repens, under the effect of NaCl and rhizobial symbiosis. Seeds of T. fragiferum and T. repens were collected from populations in the wild, and plants were cultivated in an automated greenhouse, two plants per container. Three basic types of planting were performed: (1) both plants were T. fragiferum (single species), (2) one T. fragiferum and one T. repens (species coexistence), (3) both plants were T. repens (single species). For every basic type, three subtypes were made: (1) non-inoculated, (2) inoculated with rhizobia taken from T. fargifer…
Abiotic Stress Tolerance of Coastal Accessions of a Promising Forage Species, Trifolium fragiferum
2021
Crop wild relatives are valuable as a genetic resource to develop new crop cultivars, better adapted to increasing environmental heterogeneity and being able to give high quality yields in a changing climate. The aim of the study was to evaluate the tolerance of different accessions of a crop wild relative, Trifolium fragiferum L., from coastal habitats of the Baltic Sea to three abiotic factors (increased soil moisture, trampling, cutting) in controlled conditions. Seeds from four accessions of T. fragiferum, collected in the wild, were used for experiments, and cv. ‘Palestine’ was used as a reference genotype. Plants were cultivated in asymbiotic conditions of soil culture. Treatments wer…
Gumiņbaktēriju simbiozes un augu mijiedarbības ietekme uz divu āboliņa sugu reakciju uz augsnes sāļumu
2017
Lielākā daļa ekoloģisko pētījumu ir veikti brīvā dabā, bet tai pat laikā ir maz pētījumu par starpsugu konkurenci un to mijiedarbību kontrolētos veģetācijas eksperimentos, lai gan ir iemesls uzskatīt, ka kopkultivācija var ietekmēt augu atbildes reakciju pret biotiskiem un abiotiskiem faktoriem. Eksperimentam izvēlējās Latvijā bieži sastopamo ložņu āboliņu un reti sastopamo, īpaši aizsargājamo zemeņu āboliņu, kuru sēklas ievāca mitrā pļavā Liepājas ezera krastā. Darba mērķis bija noteikt kā mainās divu āboliņu sugu reakcija pret augsnes sāļumu augu mijiedarbības un gumiņbaktēriju simbiozes ietekmē. Eksperimentam ierīkoja 90 veģetācijas traukus, kopā 18 dažādus variantus, kas atšķīrās pēc su…
