“…Codependencies of SIF on temperature and moisture are consistent with plant physiology, in general [26], and tea plants, in particular [27,28]. In tea plants the foliar relative water content and water potential decline when moisture in the soil is limiting, decreasing the photosynthetic rate via stomatal closure [5,27]. Leaf temperature, which is typically 2°C-12°C higher than air temperature [3], also directly influences the photosynthetic rate of tea, shoot growth, and the rate of shoot initiation [2], with adverse effects at high temperature.…”

“…There is only a limited amount of suitable land that would allow for the adaptation of Kenyan tea production to a changing climate by moving farms to higher elevation [36], but there does appear to be the potential for adapting to warmer conditions through planting tea cultivars with higher optimal temperature thresholds and improved ability to access soil moisture through greater rooting depths [3]. Such tea cultivars maintain a higher relative water content and exhibit less decline in photosynthesis under water stress [5]. Planting such cultivars, however, involves a long-term commitment because tea plants require at least three years of maturation before harvest and have an economic lifespan of 50-60 years [3].…”

“…К наиболее эффективным стратегиям адаптации растений, в том числе чая, к засухе относятся так называемые механизмы избегания воздействия стресса посредством сокращения жизненного цикла, периода вегетации и цветения, продолжительности плодоношения, которые направлены на снижение потери воды организмом (15,16). Важнейшими морфологическими признаками адаптации растений служат характеристики корневой системы (биомасса, длина, глубина и плотность корней) (17)(18)(19), соотношение биомассы корни/побеги, число и размер листьев, площадь и характер листовой поверхности, соотношение массы листа к поверхности, структура фотосинтетического аппарата, строение и форма хлоропластов (20)(21)(22)(23)(24). Главные физиологические механизмы избеганияснижение потери воды посредством устьичного контроля транспирации (25)(26)(27), уменьшение числа и размера устьиц (28), повышение вязкости цитоплазмы, поддержание осмотического потенциала клетки.…”
