Influence of bulb topping and intra row spacing on yield and quality of some shallot (Allium Cepa Var. Aggregatum) varieties at Aneded woreda, western Amhara

Lack of improved varieties and production practices have been the bottlenecks of shallot productivity in Amhara region. Bulb topping have been traditionally practiced among shallot growers in the region though its importance remained controversial among interested groups worldwide. There was no recommended spacing for shallot in the study area and farmers used to practice broadcasting. Thus, a field experiment was...

Limonene synthase gene expression under different concentrations of manganese in Cuminum cyminum L.

Semi-quantiative real time polymerase chain reaction (SQ-RT-PCR) was applied to study Limonene synthase (LS) gene expression pattern and the response to different concentrations of manganese in different organs of cumin (Cuminum cyminum L.). The results revealed that the gene was expressed in very small (< 2 mm) and small (3-4 mm) flowers and also in shoots, while it was not expressed in roots, leaves, medium...
