چکیده

for determination of water stress effects in different growth stages of sugar beet and optimum water usage on quantity and quality of sugar beet, this study was performed using randomized complete blocks design in factorial experiment with 12 treatments and 4 replications from 1999 to 2001 in agricultural research center of hamadan. the first factor was non-irrigation in 3 stages of growth (s1-s3) and the second was non- irrigation with 4 levels (i1-i4). experiment was performed with 12 treatments and a control without drought stress. the combined analysis results showed that there was significant difference among root yield, sugar yield and white sugar yield in interaction of different growth stages and year levels. there was significant difference (p≤ %1) in interaction of treatments and year on relative water content and soil moisture percent. there was significant difference in interaction of different growth stages and year on water use efficiency for root yield, sugar yield and white sugar yield. maximum water use efficiency obtained from s1i2 (not-irrigated for two times in the leaf growth stage) and the minimum obtained from s2i4 (not-irrigated for four times in the root growth stage).non-irrigation for more than one time in sugar beet different grail stages cause damage on qualitative and quantitative characters. in general, drought stress in relation of the time and stress intensity decreased yield and quality of sugar beet. reduction of root and sugar yield root growth and sugar accumulation stages was more severe.

Effect of drought stress on some physiological properties and antioxidant activity of Achillea tenuifolia Lam.

Background & Aim: Osmotic stress in plants lead to increase free radicals and plants use different mechanisms to scavenge these radicals. So, researchers apply stresses especially drought stress to increase secondary metabolites such as phenolics, and antioxidants. One of the valuable medicinal plants is yarrow (Achillea tenuifolia) which is a perennial plant with different medicinal a...

some properties of fuzzy hilbert spaces and norm of operators

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
