چکیده

the aim of this study was to investigate the effect  of irrigation period on the quality and quantity of yield and some morphological and physiological traits of three multigerm sugar beet genotypes named bp mashhad, bp karaj and 191. the experiment was in a split  plot  based on randomized complete block  design , carried out  at motahari research station of sugar beet seed research institute in kamalabad , karaj in 2005. the main plots consisted of three irrigation periods, non-stress, medium stress and sever stress (80, 130 and 180 mm evaporation  from  class a pan , respectively) and the sub plots consisted of three genotypes. irrigation treatments were applied at 6-8 leaf stage. the amount of irrigated water in each treatment was measured by wsc flom. based on the results, the mean root yield of each treatment was 37.97(non-stress), 17.78(medium stress) and 15.46 (severe stress) ton/ha, and dry root weight of each treatment was 850 (non-stress) , 459(medium stress) and 15.46 (severe stress) g/m2. all the factors used affected yield, leaf area index , dry root and shoot weight in severe stress condition compared to the non-stress condition . the severe  stress condition decreased root yield but increased sugar contents. drought stress also decreased other measured traits such as root dry weight, total dry weight and leaf area index. two genotypes bp mashhad and bp karaj were evaluated as drought  tolerant  genotypes.

Changes in Carbohydrates and Sugar Yield in Sugar Beet (Beta Vulgaris L.) Under Different Biofertilizers and Irrigation Closed Time

Objective: Many agronomic practices may need to be adjusted to maximize yield and quality of sugar beet. Thus agronomic package must be always modified. This sutdy was laid out for evaluation of changes in carbohydrates and sugar yield in sugar beet (Beta vulgaris L.) under different biofertilizers and irrigation closed time at Dorud region of Iran, during 2013. Methods: The experiment...

Assessment of drought stress tolerance of sugar beet (Beta vrulgaris L.) genotypes in furrow and tape irrigation systems

To evaluate sugar beet germplasm for identifying drought tolerant genotypes, precise methods are required for application of drought stress. A field experiment carried out as split arrangments in randomized complete block design with four replications in Karaj, Iran in 2007 and 2008. Main plots consisted of eight irrigation treatments with furrow and tape drip irrigation methods after 30 mm (ex...

Sugar Beet Genotypes Grouping under Normal and Saline Conditions

For ranking and grouping of full-sibs and hybrids of sugar beet obtained from breeding programs, two separate experiments were carried out at the farm of the Agricultural and Natural Resources Research Station of Miandoab in 2017 under saline and normal conditions. For this purpose, 17 full-sibs and 28 hybrids differing in resistance and susceptibility to environmental stresses were investigate...
