The Effectiveness of Some Herbaceous Species for Montane and Subalpine Revegetation
The low level of plant nutrients in exposed high-altitude subsoils, aod the effects of soil frost and needle ice on plants attempting to colonise these subsoils combine to make natural revegetation very difficult. Artificial revegetation trials established in 1965 at three sites in the Canterbury mountains tested the effect of a fertiliser mixture \vhich suppJied a wide range of nutrients, and ...
متن کاملeffect 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...
Ideal Sowing Depth for Sweetgum Seed
Seed was collected from a sweetgum tree in Washington County, Miss., in the fall of 1964 and stored at 35° to 40° F. for 4 months. Prior to sowing, the seed was stratified moist for 30 days at the same temperature. About 4 inches of loose silt loam was placed in 4inch clay pots. The soil was settled by sprinkling lightly with water and then leveled. Fifty seeds were placed in each pot and cover...
متن کاملShrub Invasion of Grassland: Recruitment Is Continuous and Not Regulated by Herbaceous Biomass or Density
Proliferation of woody plants in grasslands and savannas since the 1800s has been widely documented. In the southwestern United States, increased abundance of honey mesquite (Prosopis glandulosa var. glandulosa) has been attributed to heavy grazing by livestock. Here, we test the hypothesis that P. glandulosa invasion of grasslands requires, first, reductions in herbaceous biomass and density s...
متن کاملPhotoinhibition of germination in grass seed--implications for prairie revegetation.
Germination photoinhibition is not a recognized cause of revegetation failure; yet prolonged sunlight exposure can inhibit germination of several grass species. This research addressed susceptibility to photoinhibition of selected native grass species used to restore Canadian prairies, and reclamation treatments to alter environmental conditions in order to release seeds from photoinhibition. U...
