摘要/Abstract

摘要：

杜鹃(Rhododendron)是极具观赏价值的花卉, 中国是全世界杜鹃资源最丰富的国家, 对杜鹃资源的开发利用具有很大潜力。在全球变暖背景下, 杜鹃遭受水分胁迫的风险快速增大, 但关于水分胁迫对杜鹃生长及生理生态指标的影响尚缺乏深入研究。该研究通过马缨杜鹃(R. delavayi)幼苗的土壤水分梯度实验, 研究其株高及地径生长差异, 并建立与生理指标的统计关系, 以期为杜鹃保护与管理等提供理论基础。2022年3月11日至10月15日, 用马缨杜鹃的二年生幼苗进行盆栽实验, 设计的土壤水分含量分别为田间持水量的15%、25%、35%、50%、70%、90%。分别在3-5月上旬和下旬以及6、7、10月的中旬测量每株杜鹃的株高和地径, 并于6-8月在每个处理中随机选择5株马缨杜鹃测定叶片渗透调节物质(脯氨酸(Pro)、可溶性糖(Ss)、可溶性蛋白(Sp))含量、抗氧化系统(超氧化物歧化酶(SOD)、过氧化物酶(POD)和过氧化氢酶(CAT)活性及丙二醛(MDA)含量)指标、光合作用(净光合速率(P_n)、气孔导度(g_s)、胞间CO₂浓度(C_i)、蒸腾速率(T_r))指标。研究结果: 1)建立了各干旱水平下的马缨杜鹃株高及地径生长响应年序日(DOY)的生长方程, 拟合精度0.94-0.99; 比较发现田间持水量15%处理下植株死亡率最高; 2)建立了各时间段马缨杜鹃株高及地径相对累积生长量随土壤含水量增加而变化的方程, 表明株高相对累积增量方程呈单峰曲线变化; 但相对地径累积增长量在DOY 161之前随土壤相对含水量增加呈U形变化, DOY 161-201之间呈直线变化, DOY 201以后呈单峰曲线变化。3)随土壤含水量增加, SOD活性、CAT活性、POD活性、P_n、g_s、T_r及Pro含量整体表现为先增后降, SOD、CAT、POD活性及Pro含量在田间持水量20%-30%达到最大值, P_n、g_s、T_r在田间持水量60%-80%达到最大值; MDA含量整体表现为逐渐降低; C_i、Ss及Sp含量则呈先降后增的变化趋势, 整体表现为在田间持水量60%-80%时达到最低值。4)基于马缨杜鹃地径日增量与各生理指标的回归关系分析, 可知回归关系达到显著水平的生理指标包括MDA含量、P_n、g_s、T_r及Ss含量, 除MDA含量与马缨杜鹃地径日增量存在一元二次函数关系外, 其余生理指标与其均为幂函数方程关系, 拟合精度为T_r > P_n > MDA含量> g_s > Ss含量。马缨杜鹃幼苗在土壤含水量68%时累计生长量(地径增量)最大, 随着土壤水分含量的改变, 生长量主要受T_r、P_n、g_s的显著促进作用和Ss含量的显著抑制作用, 以及MDA含量较低时的一定促进作用和超过33.53 nmol·g^-1后的抑制作用, 进一步解释了水分胁迫下马缨杜鹃幼苗生长的生理机制。

Abstract:

Aims The Rhododendron as a high ornamental value genus has a great potential for resources development and utilization in China, which provided the most abundant rhododendron resources in the world. The risk of drought stress is rapidly increasing in the context of global warming, but the effects of water stress on growth and physiological and ecological indexes of rhododendrons are still lacking. In this paper, the height and ground diameter growth increment of R. delavayi under the drought stress were studied, and the numerical relationship of the growth increment response to the physiological indicators were established to provide a theoretical basis for the future protection and management of rhododendron.
Methods Pots experiment with 2 years old seedlings of R. delavayi were carried out from March 11th to October 15th, 2022. The water stress gradient was set as 15%, 25%, 35%, 50%, 70%, 90% of the field water holding capacity respectively. The height and ground diameter of each R. delavayi were measured in early and late of March, April, May and in the middle of June, July and October. The physiological index of osmotic system (proline (Pro), soluble sugar (Ss), soluble protein (Sp) contents), antioxidant system (superoxide dismutase (SOD), peroxidase (POD), catalase (CAT) activity, malondialdehyde (MDA) content) and photosynthesis system (net photosynthetic rate (P_n), stomatal conductance (g_s), intercellular CO₂ concentration (C_i), transpiration rate (T_r)) were measured in June, July, and August by randomly selecting five seedlings in each treatment.
Important findings 1) The equations of rhododendron height and ground diameter response to the day of year (DOY) were established under each drought gradient with the fitting accuracy between 0.94-0.99. The mortality was the highest under the treatment of 15% of the field water holding capacity. 2) The equations of the relative cumulative tree height response to the soil water content were established with the unimodal curve variation. While that of ground diameter response to the soil water content shows the U shape variation with the increase of soil water content before DOY 161, the linear pattern with that between DOY 161-201, and the unimodal curve variation after DOY 201. 3) With the increase of soil water content, SOD activity, CAT activity, POD activity, P_n, g_s, T_r and Pro content increased firstly and then decreased, the SOD activity, CAT activity, POD activity and Pro content reach the maximum value at field water holding capacity of 20%-30%, P_n, g_s and T_r reach that value at 60%-80%; MDA content gradually decreases; C_i, Ss and Sp contents decrease first and then increase, reaching the minimum value at field water holding capacity of 60%-80%. 4) Based on the regression analysis of the daily increment of ground diameter and the physiological indexes, the significant regression relationship index includes MDA content, P_n, g_s, T_r and Ss content. Except the relationship of daily ground diameter increment response to the MAD was quadratic function, the relationship of that to the other physiological indexes were power equation, the fitting accuracy of the relationships was T_r > P_n > MDA content > g_s > Ss content. The cumulative growth (diameter increment) of R. delavayi was the most when the soil content was 68% of the field water holding capacity. With the soil water varying, the growth was mainly promoted by T_r, P_n and g_s, but inhibited by Ss content. The MDA content promoted the growth when it was lower than 33.53 nmol∙g^-1, but it turned inhibited the growth when it was higher than 33.53 nmol·g^-1. This has further explained the physiological mechanism of R. delavayi seedlings growth.
