A new study published in Nature Plants has found that multifactorial stress can lead to divergent responses in citrus. The study looked at two citrus species, orange and grapefruit, grown under varying levels of water, nitrogen and potassium. The results showed that the two species responded differently to the changing environmental conditions. The orange trees had higher relative growth rates when nitrogen levels were low, while the grapefruit trees had higher relative growth rates when potassium levels were low. This suggests that the two species adapted differently to the changing environmental conditions, highlighting the importance of understanding species-specific responses to multifactorial stress.
