Why doesn`t fruit have a good color?
There are Five factors Temperature affacts coloring. Low temperature promotes the formation of anthocyanins, while high temperature has the opposite inhibitory effect, which is why fruit trees often appear in producing areas with high temperature for a long time during the coloring period, where the fruit is very sweet and the fruit is ripe, but its color has not yet reached the standard for ...

Influence of nitrogen fertilizer on Cd and Zn accumulation in rapeseed (Brassica napus L.) biomass
Diffuse soil contamination with heavy metals and Cd in particular is a matter of serious concern. Application of conventional remediation methods usually is not feasible due to the large territories and relatively low heavy metal content. Thus, phytoremediation is seen as an alternative. Rapeseed was grown on Cd and Zn contaminated as well as clean soil under the greenhouse conditions. Solid and ...
