在自然界中,种子在土壤中萌发后,将迅速穿破土层获取光照进行光合作用等生理活动。此时,幼苗下胚轴或茎迅速伸长,双子叶植物的子叶闭合并形成弯钩,以克服出土的压力。幼苗出土见光后,下胚轴或茎的伸长受到抑制、弯钩打开、子叶张开、叶绿体发育完善并合成叶绿素,进行光合作用。土壤下的暗形态建成和见光后的光形态建成是大多数种子植物所必须经历的生长发育过程。
Effects of different levels of compost application on the amounts and percentage distribution of organic N forms in whole soils and particle size fractions were investigated. Soil samples were collect...
A study was conducted in order to assess the effect of different N fertilization forms (ammonium sulfate, urea, calcium nitrate and ammonium nitrate) and biostimulants foliar application (potassium h...
The current paper reports about the influence of different levels of fertilization and agricultural practices (i.e. shallow and deep ploughing) on the total content of potassium (Ktot) and its forms i...
According to experimental results of two crop rotation cycles higher soil microbiological activities (i.e.b-Glucosidase and dehydrogenase activity) were obtained from soil samples of winter lentil plo...
Samples from 8 widespread soil series from Adıyaman Çamgazi Plain were equilibriated at a constant temperature with 16 different solutions containing 0 to 50 mg/ml phosphorus in batch-type...
Runoff from clayey soils often contains abundant particulate phoshorus (PP), part of which may solubilize in surface waters. Monitoring losses of potentially bioavailable forms of PP is expensive, cal...
