Pattern of variation for seed characteristics in Turkish populations of Cucurbita moschata Duch.
Pumpkin population seed dimension variation multivariate analysis
2011/1/11
Pumpkins are one of the most important Cucurbit crops in Turkey. For this research, 40 populations of pumpkin, Cucurbita moschata Duch., were collected from different regions of Turkey and variation i...
Genetic variation of leaf antioxidants and chlorophyll content in safflower
Safflower Carthamus tinctoriuos antioxidant carotenoids chlorophyll
2010/9/14
An efficient antioxidant defense system represented by enzymatic and non-enzymatic forms is important in the control of oxidative stress caused by free radicals and other reactive species. Leaf antiox...
Variation in Seedling Growth within a Rice (Oryza sativa L.) Cultivar and Its Effect on Seedling Salt Tolerance Evaluation
Embryo weight Rice cultivar/line Salt tolerance Seedling growth
2009/8/6
The variation of seedling growth, which may affect seedling salt tolerance, of 12 rice cultivars was examined based on the pattern of seedling fresh weight histogram. Some cultivars showed a normal di...
A Study on the Interspecific Variation of Spikelet Structure in the Genus Oryza
Anther cuticle Anther length Cultivated Rice Scanning electron microscope Spikelet
2009/8/5
The objectives of this study were to clarify the interspecific variation on (i) the structure of spikelet and reproductive organs, (ii) the relationship between the size of spikelets and the reproduct...
Grain Filling Mechanisms in Spring Wheat:VI. Cultivar variation in nitrogen metabolism and changes in assimilate shortages
Grain filling phases Nitrogen metabolism Nitrogen percentage in grain Shading treatment Spring wheat varieties
2009/7/27
Improvement of wheat flour quality, an increase in grain nitrogen content accompanied by an increase in grain yield, is required through cultivation techniques and breeding program. Changes in nitroge...
Regularity in Variation of Leaf Color and Nitrogen Distribution in Half-Leaf Blades by Leaf Position on the Stems of Rice Plants:II. Uneven translocation of nitrogen between outside and inside half-leaves
Chlorophyll meter value Distribution Half-leaf blade Leaf blade width Nodal root Translocation
2009/7/27
We have reported in a previous paper that the outside half-leaf had a smaller volume and deeper leaf color than the inside half-leaf. The half-leaf color was not dependent only on the difference in le...
Genotypic Variation in the Development of Seminal Root System of Rice under Different Culture Conditions in vitro
Genotypic variation in vitro Lateral root Link length Oryza sativa L
2009/7/23
To elucidate genotypic variations in the root system architectures of rice, which are determined by the emergence (branching) and elongation of lateral roots, we compared the development of seminal ro...
Factors causing Variation of Rice Quality Change and Their Regional Difference in Tochigi Prefecture—Analysis of Data from the Regional Trials for Dozens of years—
Regional difference Rice quality Paddy rice Regional trial
2009/7/7
From the regional trials in Tochigi prefecture for dozens of years, we examined the factors causing variation of rice quality (appearance) and their regional difference in Tochigi prefecture. Sowing ...
Intra-plant variation for progress of cell division in developing oat grains: a preliminary study
Avena sativa L. cells pollination filling period naked oat position grain
2010/8/12
Development of an oat panicle proceeds from the uppermost terminal spikelet downward to the base of the panicle. The intra-panicle variation in development is likely to influence potential grain size....
