Four wells were studied for the period from the month of November 2019 to February 2020, the chemical and physical analyzes were carried out in the Environmental Laboratory of the College of Science, Tikrit University. Electrical conductivity values rates ranged between (590-3492)µs/cm.pH values rates ranged (7.02-7.85). The sulfate values ranged between (49.672-796.279) mg/L. Dissolved solids of well water were (753-3614) mg/L. Total alkalinity values were low during study period, as recorded (84.5-174.25) mg/L. The chloride ions values rates ranged between (52.5-241.25) mg/L. Reason of groundwater very hardness due to geological factors of study area ,Which was mostly the result of ion bicarbonates , ranging values of total hardness, calcium and magnesium hardness between (795-1905) mg / L, (610-1025) mg / L, (135-1010) mg/L respectively. As for heavy metals, the study recorded values for lead whose rates ranged between (0.355-0.509) mg/L, while zinc recorded values ranging between (0.033-3.841) mg/L, The results of the study showed that the physicochemical parameters of well water were not conformity with the Iraqi and international specifications for drinking water, except for well 2. The research aims to assess the water quality of some groundwater wells and indicate its suitability for irrigation and drinking in the light of international and Iraqi standards.

A multitude of natural and manmade events can generate physiological fasciation. Insect assault, mechanical pressure and/or tension during growth in some species such as asparagus and liana species, and sowing time and density are all-natural environmental influences. One of the original seven Mendelian pairs of traits was the fasciated variety of Pisumsativum L. (formerly known as P. umbellatum; Synonyms: mummy pea, crown pea, poisturk, poiscoronne). In many species, it is genetically determined. FASCIATA is the name of the gene that causes fasciation to occur (FA). Because of the great level of control over the plant material and growth circumstances that in vitro produced fasciated plants provide, they can be useful models for investigating the causes and development of fasciation.

Four wells were studied for two seasons from November, December 2016 and January 2017. Results of this study showed that there was a seasonal variation in some chemical and physical factors. The groundwater was neutral because pH values were ranged (7-8.6). Electrical conductivity values were between (2543-50305) micro siemens. Total hardness values were within permissible limits (1200-2800 mg/L). Calcium and magnesium hardness between (1000-1950) mg /L, (100-1282) mg /L, respectively. Total dissolved solids were between (261-3245). Chloride ions (Cl-) in groundwater of studied samples were within the permissible limits for watering of animal...
