The scleractinian coral Pocillopora damicornis type β is known to present a mixed reproduction mode: through sexual reproduction, new genotypes are created, while asexual reproduction insures their propagation. In order to investigate the relative proportion of each reproduction mode in P. damicornis type β populations from Reunion Island, Indian Ocean, clonal propagation along the west coast w...

Oriental hybrid lily “Arabian Red” mother scales were stored in moist cocopeat and perlite (1:1) for 3 or 5 months at 25 ̊C. The numbers of scale bulblets per mother scale were nearly identical in two durations. Increasing storage duration promoted the growth of roots (number and length) and No. scales per scale bulblets. And, diameters of scale bulblets were more in longer storage duration (5 m...

Sex and recombination are central processes in life generating genetic diversity. Organisms that rely on asexual propagation risk extinction due to the loss of genetic diversity and the inability to adapt to changing environmental conditions. The fungus-growing ant species Mycocepurus smithii was thought to be obligately asexual because only parthenogenetic populations have been collected from ...

Bamboo possesses various characteristics that make it a promising renewable biomass resource. These include rapid growth, early timber production, strong adaptability, high yield, ease of planting, wide distribution, and processing. With the increasing demand for bamboo resources, propagation, species selection, breeding have always been focus research. However, long unpredictable flowering cyc...

This paper presents a study of the intertemporal propagation of distributional properties of phenotypes in general polygenic multisex inheritance models with sexand timedependent heritabilities. It further analyzes the implications of these models under heavy-tailedness of traits’ initial distributions. Our results suggest the optimality of a flexible asexual/binarymating system. Switching betw...

The investigation was conducted on wet and dry seasons of Ethiopia during the year 2012/2013 at Wondo Genet Agricultural Research Center Nursery site. Four levels of cutting size and three levels of cutting positions were arranged in randomized complete block design with three replications. Data on seedling height, branch number/seedling, root number/seedling, root weigh/seedling, root length/s...

Neotyphodium endophytes are asexual, filamentous fungi, mutualistically associated with diverse cool season grasses. Infected seeds and vegetative organs of infected host plants are the only known modes of propagation of the asexual endophytes. In the last decade certain Epichloë and Neotyphodium-infected grass species have been shown to have epiphyllous structures of the endophytes, hyphae, co...
