Productive tiller percentage (PTP) is the only available comprehensive indicator of rice population quality. However, productive panicle number (PN) has a great effect on its characterization accuracy. Panicle exsertion an important but difficult to describe morphological index; therefore, it cannot be easily determined. The aims this study were develop heading uniformity (HU), which describes ...

We recall that according to [3], a function φ : X → [−∞,∞) is called quasiplurisubharmonic (quasi-psh for short) if it is locally equal to the sum of a smooth function and a plurisubharmonic (psh) function. Then there exist a constant C ∈ R such that √ −1∂∂φ ≥ −Cω in the sense of currents on X . We say that a function ψ has logarithmic poles if for each open set U ⊂ X there exist a family of ho...

The adaptation of plants to natural environments depends on the adaptation of flowering-time control at the appropriate season to set seeds. Possible molecular mechanisms underlying this adaptation have recently been revealed. In Arabidopsis thaliana, a model long-day plant, control of floral transition by vernalization and long-day floral promotion pathways is a key regulator in adaptation to ...

the construction of molecular maps and identification of genomic regions controlling quantitative traits have great significance for plant breeders. in this study, a genetic analysis of quantitative trait loci (qtls) affecting the heading date of rice was performed using an f2 population of a cross between two iranian landrace cultivars, domsephid and gerdeh, comprising 192 plants. an approxima...
