Impact of mycorrhizae and irrigation in the survival of seedlings of Pinus radiata D. Don subject to drought

In drought condition, plants increase survival chance by adjusting their functional traits and by biological associations. Mycorrhizae association and artificial watering have been shown to increase plant survival under drought, especially at early developmental stages when plants are more susceptib...
