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。
The aim of the experiment was to compare the effect of inorganic and organic forms of copper (Cu) supplementation on Cu status of goats and their kids, colostrum and milk composition and quality, and ...
Effects of different forms of dietary selenium (Se) supplementation on gene expression of cytoplasmic thioredoxin reductase (TrxR1), selenoprotein P (SelP), and selenoprotein W (SelW) in broilers were...
Effect of various doses and forms of selenium (organically bound vs. inorganic) on selected parameters of ruminal fluid and blood in sheep was evaluated. The trial was performed with 15 sheep divided ...
The activity of GSH-Px in the blood of the kids tended towards higher values in the supplemented groups than in the control group, but the values were significantly higher (P < 0.05) only in group...
Summerling (six-month old) noble crayfish fed two forms of freshly decapsulated (FD) Artemia cysts more than tripled their weight during a 75-day experiment under controlled conditions. Final survival...
The aim of this trial was to compare the effect of supplementation of goats with different forms of selenium on the metabolism of their kids at the time of weaning. The experiment was performed with 4...
Cell wall deficient (CWD)-forms or L-forms of bacteria are characterized by a complete or partial loss of cell wall components and by the change of cellular shape. CWD-forms (spheroplasts) of bacteria...
The article presents original results of research on the humus form dynamics in a semi-natural European beech stand in the National Natural Reserve Voděradské bučiny, in the area of Training Fo...
Humus forms dynamics and characteristics of different forest sites were studied in the area of Smrčina Mt. in the Šumava National Park territory. The study was performed in vital Norway spru...

As an essential element, zinc also is a heavy metal. Non-heading Chinese cabbage showed obvious tolerance to Zn stress in former research. To further understand the mechanisms involved in Zn adaptabil...
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...
