Analytical study of cow dung and poultry manure on survival and health performance of plantain genotypes in macropropagation acclimatization process
Abstract
Macropropagation of plantain is not complete until successful acclimatization of generated plants
with environment is achieved. After detaching plantlets from mother corm, high percentage of plantlets is usually
lost during acclimatization due to shock and environmental change. Hence, the need for study on the efficient means of introducing generated plantlets to the field. This study of cow dung and poultry droppings as manure source was done using 3 different plantain genotypes (‘Atagafong’, ‘Nble paul’ and ‘Owom’). The physicochemical
properties of the substrates and the growth performance of the 3 plantain species were analyzed. Nine (9) replicates each of the genotypes were potted in top soil (TS) which served as control, substrate with cow dung (CT) and substrate with poultry dropping (PT) on ratio of 2:1 for top soil and manure. The result from acclimatization of plantain species revealed that in CT, 11% died while 89% survived and were healthy in ‘Nble
paul’, 78% survive and were healthy in ‘Atagafong’ but 22% survive and were unhealthy while in ‘Owom’, 11% died, 11% survived but unhealthy and 78% survive and were healthy. In poultry dropping all 100% of the 3 genotypes died within 2 weeks. However, in soil, 56% of ‘Nble paul’, 33% of ‘Atagafong’ and 44% of ‘Owom’ genotype died, 33% each of ‘Nble paul’ and ‘Atagafong’ survived and 11% of ‘Owom’ was unhealthy, while 11% of ‘Nble paul’, 33% of ‘Atagafong’ and 44% of ‘Owom’ survived and were healthy. No significant difference at5% probability level was observed across the survivability of plantlets in substrates. This study revealed among the manures worked on, cow dung is better forplantain plantlets’ acclimatization.

During meiosis in eukaryotes, genetic recombination involves the pairing of homologous chromosomes. This may be followed by information transfer between the chromosomes. The information transfer may occur without physical exchange (a section of genetic material is copied from one chromosome to another, without the donating chromosome being changed)
