Desiccation tolerance of Cissus quadrangularis assessed in a greenhouse experiment

Cissus quadrangularis is a succulent vine that degrades forests where it is not native by growing over trees and causing them to break or by impeding regeneration. Methods for its control have been tried but no satisfactory approach has been found yet. Thus, we carried out an experiment to analyze how much desiccation Cissus can endure before losing its ability to grow when rehydrated, using fragments of 0.5, 1, 2, and 3 internodes to test if desiccation tolerance was affected by fragment length. Additionally, we tested whether chemical treatment to break down the cuticle facilitated desiccation. We found out that Cissus remains viable after losing up to 80% of its weight, with shorter fragments losing viability at 70% weight loss. Acetone treatment did not accelerate desiccation time. Cissus has a remarkable tolerance to desiccation. Therefore, management strategies should ensure complete desiccation of Cissus fragments to prevent its regrowth. Reducing fragments to smaller sizes could..., This data is a product of two controlled experiments in the greenhouse. The available data is the data gathered during the course of the experiments. The data has not been transformed., , # Cissus quadrangularis desiccation experiment [https://doi.org/10.5061/dryad.gtht76hvn](https://doi.org/10.5061/dryad.gtht76hvn) This dataset contains two files with the results for two experiments. 1.The first file \"desiccation\" contains the results for a dessication experiment, to investigate C. quadrangularis resistance to desiccation and if that resistance is a function of fragment length. We took Cissus fragments of different lengths (0.5, 1, 2, or 3 internodes) and desiccated them at room temperature in the greenhouse and weighed them every week to monitor their mass loss. We weighed them until they reached a certain mass loss category (measured as a percentage of mass loss). We then repotted Cissus and assesed their viability. We considered that a cissus fragement was viable if it had shoot or root growth. We found that cissus fragments remained viable even after losing 80% of their mass content. 2.The second file \"acetone\" contains the results of a second experiment in whi...四角白粉藤（Cissus quadrangularis）是一种肉质藤本植物，在非原生分布区中，其会覆压树木导致植株折断，或阻碍植被更新，进而破坏森林生态系统。目前虽已尝试多种防治手段，但尚未找到令人满意的防控方案。因此，本研究开展了相关实验，以探究该物种在丧失复水生长能力前所能耐受的脱水程度：实验采用0.5、1、2、3节间的植物切段作为材料，验证切段长度是否会影响其脱水耐受性。此外，本研究还测试了通过化学处理破除角质层是否能够加速脱水进程。 研究结果表明，该植物在体重损失高达80%的情况下仍可保持活力，而较短的切段则在体重损失达70%时便会丧失生存活力。丙酮处理并未缩短其脱水时长。综上，四角白粉藤具备极强的脱水耐受性。因此，防控策略应确保该植物切段完全脱水，以阻止其重新萌发。将切段进一步缩减至更小尺寸可…… 本数据集源于两项温室受控实验，所公开的数据为实验过程中采集的原始数据，未经过任何变换处理。 # 四角白粉藤脱水实验（Cissus quadrangularis desiccation experiment） https://doi.org/10.5061/dryad.gtht76hvn 本数据集包含两个文件，分别对应两项实验的结果： 1. 第一个文件"desiccation"：对应脱水耐受性实验，旨在探究四角白粉藤的脱水抗性，以及该抗性是否与切段长度相关。研究人员截取不同长度的四角白粉藤切段（0.5、1、2或3节间），在温室室温环境下进行脱水处理，每周称重以监测其体重损失情况，直至达到预设的体重损失等级（以体重损失百分比计）。随后将切段重新栽种，评估其生存活力：若切段长出芽或根，则判定为具有活力。实验结果表明，四角白粉藤切段在体重损失达80%时仍可保持生存活力。 2. 第二个文件"acetone"：包含第二项实验的结果，原文此处未完成。
