Seasonal dynamics and adaptation strategies of krummholz forming Rhododendron campanulatum to water availability at high-altitude Himalayan treeline environments.

ABSTRACT: This study investigates the water relations mechanism of Rhododendron campanulatum (D. Don) in treeline areas of the Himalayan region, emphasizing its vital role in ecosystem dynamics. The species, commonly found as krummholz forms at treeline ecotones, exhibits notable population advancement 1.4 m/yr, which could lead to the densification of the ecotone in the future. Seasonal measurements of soil moisture at depths of 15cm, 30cm, and 45cm, as well as pre-dawn (ΨPD) and mid-day (ΨMD) water potentials, and leaf conductance in the forenoon (gwAM) and afternoon (gwPM), were conducted for both trees and seedlings. Significant variations were observed among sites, seasons, and years across various parameters, including soil moisture and water potential components. The study underscores the mos
