Due to the existence of salinity and high temperature and sensitivity of some plants in most regions of Iran, especially in Khoozestan, there are a lat of difficulties in the planting and husbandry of lawn. Therefore an experiment was carried out under field conditions, to investigate the effect of seven levels of salinity as: Karun river water with EC of 1.09, distilled water (0.01) and irriga...
In order to investigate the relationship between morphological properties and choose suitable criteria for improving this research yield on ten new breeding lines and varieties of rice (control) modified rice cultivation area (Shiroodi cultivar) in the crop during 2010 in Tonekabon Rice Research Station in a randomized complete block design with four replications. The results showed that rice g...
a number of 36 varieties of rice were compared for different traits. the correlation coefficient of grain yield with tiller number, harvest index, length of grain, ratio of length to width of grain, amylase content, days to 50 percent flowering and days to full maturity were positive and significant (p
A model which describes tiller density dynamics in bahiagrass (Paspalum notatum Flügge) swards has been developed. The model incorporates interrelationships between various morphogenetic and structural components of the sward and uses the inverse of the self-thinning rule as the standard relationship between tiller density and tiller weight (a density-size equilibrium) toward which tiller densi...
Operator performance on the tiller-motor system was investigated in a field survey and in a tracking simulator. Boat operators in Study 1 reported both control difficulties and discomfort, when using their tiller-motor system. Participants in Study 2 operated a tiller-motor simulator of a boat navigating a river over a 20 min period. Directional and speed control performance was found to be poo...
in order to study of variation and relationships between morphological traits with yield and its components in three grain sorghum cultivars (kimia, sepideh and payam) and nine promising lines (mgs1-mgs9) received from seed and plant improvement institute, an experiment was conducted as randomized complete block design with four replications in birjand agricultural research station, in two grow...
Tiller number is one of the key factors that influences rice plant type and yield components. In this study, an EMS-induced rice tiller suppression mutant ts1 was characterized. Morphological and histological observations revealed that, in the ts1 plants, the tiller buds were abnormally formed and therefore cannot outgrow into tillers. With an F2 population derived from a cross between ts1 and ...
