Carbon and Nitrogen Dynamics with Aging in Seminal Root System of Rice Seedling
Aging Carbon Lateral roots Nitrogen Partitioning
2009/7/29
The allocation pattern of carbon (C) and nitrogen (N) with aging among several organs of rice seedling was investigated with particular attention to the difference in seminal root axis (SRA) and conco...
Effects of Physiological and Morphological Characteristics of Root Tips Excised from Rice Seminal Roots on Subsequent Growth in vitro
Age C·N content Elongation rate Excised root culture Lateral root Oryza sativa L
2009/7/29
Tissue culture of excised root is a useful method with which genetic variation of plant root itself can be determined without the influence of shoot. We aimed to determine the effects of age and elong...
