Abstract: 

To characterize some important- eco-physiological aspects of Alhagi pseudalhagi growth, the present investigation was conducted at the farm of Khorasan Agricultural Research Center during 2004-2005. Various botanical characteristics including root structure and existence of starch in root were studied. Number of seeds per pod, pod length and test weight were recorded. A number of field and pot experiment were carried out to determine germination ability of roots in different temperatures. Different depths of plow were examined to investigate recovery rate after cutting. Growth analysis indices were calculated using parameters including height, maximum diameter of canopy and dry matter. Results revealed that, roots have originated from shoots and, therefore, may be considered as rhizome. Regeneration was just observed in 5% of roots with at least 30 cm length. Significant differences were noted among different levels of root cutting concerning germination rate, plant height, secondary branches, fresh and dry weight. Rhizome growth rate was calculated as 0.0934 cm. GDD-1.
