in this investigation, the effect of different treatments on breaking of seed dormancy of almond species and peach seeds include prunus scoparia spach, p. haussknechtii bornm, p. communis l. and p. persica l. was studied to determine their seed germination percentages. first, mature seeds, without endocarp were treated with two percent tmtd® (tetramethylthiuram disulphide) fungicide solution fo...
Seed’s dormancy is considered as one of the effective factors in seeds germination and consequently in the growth of seeds of many plant species. Shortening the dormancy period and enhancing the germination percentage in fruit types could be a valuable strategy for the seed researchers and plant nurseries. In this research the seeds of mature fruits of different almond cultivars including late-...
sesame (sesamum indicum l.) seed and oil have long been used widely as healthy foods to supply energy and prevent aging. some of the main active anti-oxidative constituents in sesame seeds are γ-tocopherol and phenols. the purpose of this study was to investigate the relationship between roasting temperature and time with γ-tocopherol and total phenolic compounds (tpc) of sesame seeds when roas...
جهت بهینه سازی شرایط تولید پروتئین هیدرولیز شده (شامل نسبت آنزیم به سوبسترا، دما و زمان) به منظور دستیابی به بالاترین خواص آنتی اکسیدانی، مینس تهیه شده از ضایعات میگوی ببری سبز (penaeus semisulcatus) پس از تعیین درصد پروتئین آن (13%، بر اساس وزن تر) با استفاده از دو پروتئاز تجاری آلکالاز و فلاورزایم بر اساس 18 تیمار تعیین شده با طرح آزمایشات سطح پاسخ برای هر آنزیم، هیدرولیز شده و با خشک کن انجم...
BACKGROUND: Seed aging is an important problem in developing countries which seeds stored in inappropriate condition. OBJECTIVES: Current research was carried out to study the effect of seed aging on quantitative parameters of wheat seeds (Chamran cultivar). METHODS: Experiment was carried out based on randomized complete block desi...
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
