Changes in the microflora on the seed surface and seed vigor of maize (Zea mays) under different conditions

This study examined how different humidity levels during seed storage affect the types of fungi that grow on maize seeds and how this impacts seed quality. Researchers found that high humidity causes different fungi to colonize seeds and dramatically reduces the seeds’ ability to germinate and grow. The fungi harm seeds by producing toxins and reducing their energy production, making stored seeds much less viable for farming.

Characterization and Biological Characteristics of Alternaria, Botryosphaeria, Pestalotiopsis, and Trichothecium Species Associated with Postharvest Loquat Fruit Rot in Yunnan, China

Researchers in China identified four types of fungal pathogens responsible for loquat fruit rot after harvest. These fungi cause different symptoms ranging from ring-shaped spots to soft decay, with infection rates between 4-12%. The study confirmed each pathogen’s ability to cause disease and found that some are more aggressive than others. This research helps growers understand what causes loquat spoilage and suggests that careful handling and cool storage can reduce losses.

Impact of nitrogen fertilization on soil microbial diversity, its mediated enzyme activities, and stem nematode population in sweet potato fields

Researchers studied how different amounts of nitrogen fertilizer affect sweet potato growth and soil health. They found that the right amount of nitrogen (64.8 kg per hectare) boosts beneficial soil bacteria and fungi while reducing harmful nematode parasites that damage sweet potatoes. This optimal fertilization level improved yields and plant health by maintaining a better balance of soil microorganisms.
