Dragon ́s blood tree, a flagship endemic species of Socotra, is threatened with extinction 23 due to lack of natural regeneration, likely because of goat herbivory and/or climatic factors. Loss of 24 dragon ́s blood tree would result in loss of other native flora, heightening the importance of 25 formulating a conservation strategy for it. Although artificial afforestation might be used to offset...

Effects of transplanted seedling density and species on sward structure of native warm-season grass (NWSG) stands were compared in a randomized complete block design. About 6-week-old NWSG (big bluestem (BB, Andropogon gerardii Vitman), eastern gamagrass (GG, Tripsacum dactyloides L.), indiangrass [IG, Sorghastrum nutans (L.) Nash] and switchgrass (SG, Panicum virgatum) seedlings were transplan...

microorganisms has positive role on seed germination and growth of plants. In the present study, its efficacy on seed germination and seedling growth of Albizia lebbeck in the nursery was studied. The seeds were sown in polybags filled with a mixture of forest soil and cow dung (3:1) and treated with 0.1%, 0.5%, 1%, 2%, 5% and 10% concentrations of MI. Most of the parameters studied (seed germi...

Globally, seagrass beds have been recognized as critical yet declining coastal habitats. To mitigate seagrass losses, seagrass restorations have been conducted in worldwide over the past two decades. Seed utilization is considered to be an important approach in seagrass restoration efforts. In this study, we investigated the effects of salinity and temperature on seed germination, seedling esta...

abstract nowruzak (salvia leriifolia) of lamiaceae family has a good capability for domestication in khorasan’s natural habitats. in order to investigate the effect of sowing design and depth in seedling emergence and permanence, a split plot experiment based on a randomized complete block design was performed with three replications. results indicated sowing design in all three parameters, sow...

Loblolly pine seedlings were grown in 1 x 5 inch biodegradable plastic tubes for 10, 12, and 14 weeks at densities of 42, 84, 126, and 168 per square foot. Seedling density and age significantly affected seedling development at time of outplant ing, and densi ty became more important as greenhouse growing t imes increased. Al l morphological characteristics measured when seedlings were planted-...

Priming of seed is intended to reduce the time germination through activation pre-germinative processes. Seed priming controlled hydration followed by a drying (dehydration) process. The physiological processes during (imbibition) were studied in detail tomato. In contrast, gibberellic acid changes dehydration phase not detail. We hypothesize that there would be change GA concentration process,...

environmental conditions including metrological parameters (precipitation, temperature, humidity and etc.) various stresses and nutrition, could affect  germination and  seeds vigor during of development, ripping and leven after harvesting of soybean seed. for this, experiments of completely randomized design ( as nested)by four replications were performed in seed laboratory of gorgon universit...

An experiment was conducted in pots at the demonstration farm of College Agriculture, University Bahri, Sudan during 2016 - 2017 seasons to study effect different NaCl concentration soil on seed germination and seedling growth sugar beet. The arranged randomized complete block design (RCBD) with three replications four treatments sodium chloride concentrations soil; they were 4 dS/m, 8 12 16 dS...

This study was conducted during the growing season of 2021 and 2022 in horticulture station located at Akre city center Duhok Iraqi Kurdistan region, aimed to investigate effect growth regulators on seedling apricot determined best concentration Gibberellin, Benzyl adenine Kinetin improve vegetative . so it consisted three GA3 (0, 250 500 mg.L-1), BA (0,150 300 KIN mg.L-1) some characteristics ...
