Karyotypic features including organizations of the 5S, 45S rDNA loci and telomeres of Scadoxus multiflorus (Amaryllidaceae)
Scadoxus multiflorus Martyn, 1795 is an ornamental plant with brilliantly colored flowers. Even though its chromosomes are rather large, there is no karyotype description reported so far. Therefore, conventional and molecular cytogenetic studies including fluorescence in situ hybridization (FISH) with 45S and 5S rDNA, and human telomere sequence (TTAGGG)n probes (Arabidopsis-type telomere probe...
متن کاملGIS-based analysis of spatial distribution patterns of growing degree-days for agricultural applications in Iran
The geographical distribution of growing degree-days (GDDs) within Iran was studied using GIS-based maps. GDDs were calculated using daily thermal parameters (daily maximum and minimum air temperature). Based on the purpose of the study and climatic conditions of Iran, the average value of 5?C was chosen for GDD calculation. The calculations were carried out using daily weather data of 113 mete...
متن کاملDetermining suitable time for exploitation/ grazing of rangeland plants using growing degree days (GDD) model
One of the key principles in rangeland management is determination of suitable times for exploitation and grazing of rangeland plants in summer and winter pasturelands. This determination of time not only prevents degradation of plant species, but also leads to optimal usage of plant yield. Multiple factors affect plant phenology among which temperature regime has the highest effect on plant de...
متن کاملMineral Requirements for Growing Swine
als must be supplied in swine rations for optimum performance. About 5 percent of the total body weight of swine consists of mineral elements. These elements are essential for most of the basic metabolic reactions in the body. They have a role in digestion; metabolism of protein, fats, and carbohydrates; and the structure of chromosomes, enzymes, nerves, blood, skeleton, hair and milk. They are...
متن کاملRequired Growing Degree-Days (GDDs) for each Phenological Stage of Fritillaria imperialis
Studying plant phenology is very important to regulate the rangeland utilization. Plant phenology can be determined by Growing Degree Days (GDDs). Since temperature varies yearly, the phenological stages may consequently differ yearly. Determining the base temperature is one of the key steps in the calculation of GDDs. The aim of this study was to calculate the required GDDs for each phenologic...
