Effects of mulch and mineral fertilizer on crop, weevil and soil quality parameters in highland banana por Ssali, H., McIntyre, B., Gold, C., Kashaija, I., Kizito, Fred

“…Soil water content was greater in the surface soil layer in the treatments that received mulch, presumably due to less surface run-off and evaporation, since there was no change in surface soil porosity. The effect of organic and inorganic amendments had no impact on weevil damage, which remained above 5% at the end of the trial. …”

Cryopreserved potato shoot tips showed genotype-specific response to sucrose concentration in rewarming solution (RS) por Vollmer, R., Villagaray, R., Castro, M., Anglin, Noelle L., Ellis, David

“…Of all the concentrations tested, 0.6 M sucrose appeared to be the best bet in terms of recovery rates across the genotypes; therefore, our routine protocol has been changed from 1.2 M sucrose to 0.6 M. The specific response to low (0.0 M) and high RS sucrose concentrations (1.2 M) was highly variable within species/subspecies and appears to be genotype specific. …”
