In this research, our aim was to determine the effects of gibberellic acid, which was applied to safflower plants (Carthamus tinctorius L. cv. Dinçer 5-118) for pollen sterility induction, on some physiological activity and endogenous hormone levels of the seeds. Exogenously applied gibberellic acid (GA3) strongly influenced the endogenous hormone levels of the seeds by decreasing the levels of...
This experiment was conducted at the Agricultural Research Station of Isfahan University of Technolgy in 2006 to evaluate the effects of planting pattern and the level of soil moisture on two safflower cultivars. A factorial split plot arrangement was used in a randomized complete block design with three replications. Two planting patternS (flat and bed planting) and two levels of soil moisture...
High-elevation ecosystems are traditionally viewed as environments in which predominantly autogamous breeding systems should be selected because of the limited pollinator availability. Chaetanthera renifolia (Asteraceae) is an endemic monocarpic triennial herb restricted to a narrow altitudinal range within the high Andes of central Chile (3300-3500 m a.s.l.), just below the vegetation limit. T...
the present research has been deducted from a provincial research project which aims at determining the relationship of variables of variables of occupational self-concept, intelligence beliefs and metacognitive with entrepreneurship among the students of payame noor university of kurdistan. the volume of the samples was 1080 students (576 female and 504 male students). the research methodology...
Generally, primed seeds produce larger and heavier plants than non-primed seeds. This may be simply due to rapid emergence and extension of leaf growth, or the influence of other physiological processes. The effect of seed pretreatment with salicylic acid (SA) on some physiological and photosynthetic characteristics of the safflower seedlings, cv. Goldasht, was examined under field condition. T...
the treatment of in completely formed pulpless teeth has presented considrable problems. these teeth have wide open apexes and the walls of the root canal diverge toward the apical tissues. mechanical preparation cannot be done in the normal manner beacause of the large initial size and the taper of apical part of the canal , a mechanical stop cannot be produced at the apex of the canal and , t...
Too often crop production is facing with different intensity of cold damage. In some years the damage is severe and has a large social and economic consequence. Therefore, selection and introduction of cold tolerant cultivars is very effective in reducing cold damage and increasing crop production. Frequently, in winter safflower yield trails in Isfahan province, depending on the intensity of w...
Developing sunflower (Helianthus annuus L.) seeds were analyzed for their fresh and dry weights, water content and wall components viz. low and high molecular weight xyloglucan and pectic polysaccharides. Seeds from two rows (6th and 12th) differing in their final dry weight and position on the capitulum were selected for the investigation. The dry weight of seed from 6th row was 69 mg while th...
Abstract Genetic basis of heterosis has been exploited for yield improvement in safflower ( Carthamus tinctorius L.) but little is known about physiological yield. The objective this study was to quantify the seed by examining 19 hybrids and their parents photosynthetic traits, its components. results showed that components high positive low negative traits most studied. There were weak non-sig...
in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...
