Role of Phenological Traits in Enhancing Yield Stability of Crops under Climate Change: A Review

Global farming is being shaken by climate change. It is altering the temperature in terms of how hot or cold it becomes, it is affecting rain patterns and it is increasing weather events which means that crops are encountering a number of new stresses and erratic production. Phenological traits refer more or less to the internal clock of the crop. They give a plant information on when to sprout, flower and ripen. They are a primary method of plant communication with the changing weather and their continued existence. This review is a summary of what has been known to maintain yields stable even as the planet is warming. The paper shows the fundamental concept of crop phenology, the primary weather factors that push it about and how the timing of developmental stages relates to the way in which a plant manufactures and consumes nutrients. What the data revealed is that with an increase in temperatures, those phases will shift more rapidly and thus crops will be exposed to certain stress at a younger age than they used to. That interferes with the amount of plant matter they accumulate, the number of seed they receive and the distribution of that seed they receive. There is also a discussion of long-term breeding, which simulates the crop schedules and monitors the progression of how plants change their timing on cameras with satellite or drone technology, all in the name of predicting and addressing future heat issues. Still, there are big gaps. This phenology is the key to surviving the climate variability of crops and it is a good direction to intelligent breeding and the climate-resistant agriculture. It must obviously implement in the betterment of crops the thinking which is driven in case we are to retain our farms as productive when the weather is not so certain.
