The article presents the results of studying some components in vitro technology clonal rootstocks and common cherry varieties, which allow to increase efficiency its application tested varieties rootstocks. Differences viability intensity development explants depending on timing their introduction into crop, characteristics genotypes composition nutrient media were established. influence mediu...

By measuring the changes in phytohormones and related enzyme activities of Malus ‘Huabiao’ scions different rootstocks during healing process grafting, this study aims to analyze effects on physiological metabolism grafting site, thereby providing reference for selection M. rootstocks. The live seedlings 1-0 hupehensis, robusta baccata were chosen as rootstocks, grafted with these spring by pas...

Rhizobium radiobacter is a significant causal agent that ranks among the top ten bacteria of molecular plant pathology in world, has largest range hosts pathogenic bacteria, and limits production leads to economic losses agriculture. The distinctive feature from other Ti plasmid, extrachromosomal structure present all virulent types. In this study, virulence five R. isolates (1A, 1B, 2A, 2B RK ...

Rhizospheric Effects of Three Citrus Rootstocks on Some Biological Properties and Phosphorus Fractions in a Calcareous Soil

Nitric oxide (NO), an endogenous signaling molecule, is involved in various physiological processes and stress responses in plants. In the present research, Pyrodwarf pear (Pyrus communis) rootstocks were grown by nutrient solution to investigate the effects of sodium nitroprusside (SNP) application as an NO donor at 0, 0.1, 0.5, and 1 mM levels on plant stress tolerance, content of ma...

PHL-C is one of the dwarf sweet cherry rootstocks which is a hybrid between P. avium L. × P. cerasus L. Direct rooting of sweet cherry rootstocks is difficult which can be solved by using in vitro propagation. Transfer of plantlets from in vitro to ex vitro limit the use of micro propagation, because of weak root systems and low survival rates. This study was conducted in order to select the be...
