in this paper the use of farm machinery in sugar beet farms in farsprovince was studied. the necessary data, with two-stage cluster sampling method in fasa, eghlid and darab cities on 2004- 2005 were collected. from 203 farmers selected for the study. 113 of them were in high level mechanization group and 90 of them were in low level mechanization group. in this study, the effect of farm machin...
Inhibitors of plant proteases can regulate the hydrolysis of proteins inside the cells and also participate in the mechanisms of plant defense against herbivore insects and pathogens. Here, we demonstrated that seeds of Eucalyptus urophylla exhibit activities of trypsin and papain inhibitors, two proteases commonly found in living cells. Low amounts of proteins of the crude protein extract of s...
Developing soybean seeds accumulate very large amounts of both soluble oxalate and insoluble crystalline calcium (Ca) oxalate. Use of two methods of detection for the determination of total, soluble, and insoluble oxalate revealed that at +16 d postfertilization, the seeds were 24% dry mass of oxalate, and three-fourths of this oxalate (18%) was bound Ca oxalate. During later seed development, ...
we have two part in this thesis, at first: the interaction of native calf thymus dna (ct-dna) with two anthraquinones including quinizarin (1,4- dihydroxy anthraquinone) and danthron (1,8- dihydroxy anthraquinone) in a mixture of 0.04 m brittone-robinson buffer and 50% of ethanol were studied at physiological ph by uv-vis absorption, florescence, circular dichroism spectroscopic methods, viscos...
Micronutrients play a great role in the production of high quality seeds, especially in terms of germination. Therefore, providing seeds with sufficient amounts of these is an important consideration in seed production. The present study was conducted as two separate experiments in the Seed Laboratory of Yasouj University in 2015. In the first experiment, the sesame seeds (cv. Darab 1) obtained...
UNLABELLED Seeds are considered to be agro-industrial residues, which can be used as source of macronutrients and/or raw material for extraction of vegetable oils, since they present great quantities of bioactive compounds. This study aimed to characterize the lipid fractions and the seeds of pumpkin (Cucurbita sp) varieties Nova Caravela, Mini Paulista, Menina Brasileira, and Moranga de Mesa a...
The proprotein precursors of storage proteins are post-translationally processed to produce their respective mature forms within the protein storage vacuoles of maturing seeds. To investigate the processing mechanism in vivo, we isolated Arabidopsis mutants that accumulate detectable amounts of the precursors of the storage proteins, 12 S globulins and 2 S albumins, in their seeds. All six muta...
The main goal of this study was to investigate the way of affecting of water in production of cucumber. From aspect of econometrics, mutual relationships of production function and expenses have been analyzed in which Translog cost function has been used. This function has been estimated using the conditional input demand functions, the shefard theorem, chemical fertilizer, animal fertilizer, l...
DOR: 98.1000/2383-1251.1398.6.65.11.1. 1578.1585 Extended Abstract Introduction: Understanding the complex characteristics that control the life span of the seed has ecological, agricultural and economic importance. Inappropriate storage conditions after harvesting destroy a large part of annual yield partly due to microbial activity in the storage. Damage from storage fungi varies based ...
In seeds, glutamate decarboxylase (GAD) operates at the metabolic nexus between carbon and nitrogen metabolism by catalyzing the unidirectional decarboxylation of glutamate to form γ-aminobutyric acid (GABA). To elucidate the regulatory role of GAD in seed development, we generated Arabidopsis (Arabidopsis thaliana) transgenic plants expressing a truncated GAD from Petunia hybrida missing the c...
