☆ Scientists show how to turn lunar soil fertile for agriculture
  + stars: | 2023-11-09 | by ( Will Dunham | ) www.reuters.com   time to read: +4 min
Researchers said on Thursday they have found a way to turn inhospitable lunar soil fertile by introducing bacteria that enhance the availability of phosphorus, an important plant nutrient. They performed experiments growing a relative of tobacco using simulated moon soil, more properly called lunar regolith, in a laboratory in China. In that study, Arabidopsis did grow, but not as robustly in the lunar soil as in volcanic ash from Earth used for comparative purposes, suggesting that lunar soil could use a little help to become more fertile. The study used simulated regolith rather than the real thing because genuine lunar soil, as one might imagine, is in short supply on Earth. "In contrast, our technique, which is a kind of in-situ resource utilization, applies microbial improvement to the lunar soil, making it more fertile and capable for plant cultivation," Xia added.

☆ Bolile provocate de virusuri la plante: ce simptome apar și cum să eviți răspândirea

Virusurile provoacă boli extrem de grave la plante, care afectează atât dezvoltarea acestora, cât și cantitatea și calitatea recoltei. Cu toate acestea, continuitatea lor în natură este determinată de numeroase căi de transmitere (vectori):Simptomele bolilor provocate de virusuriDupă pătrunderea în plante, virusurile provoacă dereglarea metabolismului, iar ca urmare se înregistrează transformări esenţiale în morfologia, anatomia şi fiziologia plantei gazdă. Mozaic, Cucumis virus 1; FOTO: lovethegarden.comCloroză, Cloroza viței de vie; FOTO: ro.farmlux.bizSimptome ce apar pe tulpină: reducerea ritmului de creştere şi scurtarea internodurilor. Simptome ce apar pe fructe: virozele se manifestă sub formă de pete inelare (Prunus virus 7), petrificarea fructelor de păr (pear stony pit), excrescenţe (peach wart). Peste iarnă microorganismele fitopatogene pot rezista:în plantele bolnave (Prunus virus 7, Vitis virus 1);în resturi de plante infectate (Nicotiana virus 1);în materialul săditor şi semincer (Prunus virus 7, Vitis virus 1, Solanum virus 2, Beta virus 2, Beta virus 4);în sol (Nicotiana virus);în corpul vectorilor (Lycopersicum virus 3 iernează în corpul insectei vector-Thrips tabaci) etc.
