Special Issue Information

Dear Colleagues,

A better knowledge of stress-driven modifications of growth and wood properties is essential for forest management in order to take directed decisions on wood productions. It is further vital for wood and fibre utilisation in the bioeconomy.

As a deviation from normal growing conditions, stress substantially affects the structural response of trees. Climate change is certainly one of the stressors currently receiving the most attention, but further abiotic and biotic stressors also lead to substantial structural changes in tree growth and thus to modifications of the wood resource.

In this Special Issue of Forests, relevant relationships between biotic and abiotic stress and structural responses of trees are discussed. Special attention is given to structural responses that modify growth and wood properties. Thus, manuscripts that deal with biotic, abiotic, and also multiple stress as interactions of biotic and abiotic stress are invited to this Special Issue. These might encompass climate-related stress but also stress caused by competition, mechanical injuries, fire, fungi, insects, or further agents. Focus should be on the structural tree response to stress.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Forests is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Salt and alkaline stress is one of the important problems restricting agricultural production and afforestation projects. This kind of stress will greatly limit the growth and development of forest trees. Recently, melatonin has been gradually realized as a strong kind of antioxidant due to its important regulatory and protective roles in the process of plant growth and development. This study takes Xin Lin 1 (Populus cathayana × canadansis ‘Xin Lin 1’) as the research object, and measures the changes of physiological indexes at different time points to verify the alleviation effect of melatonin under salt and alkaline stress. In this experiment, plants have different behaviors in the face of different levels of exogenous melatonin. Among them, low concentrations of melatonin (50 μM and 100 μM) were more helpful to reduce the levels of MDA and osmotic regulators in leaves. At this level, the SOD and CAT content in the leaves increased significantly. Melatonin at 800 μM was more inclined to induce POD, but its activity was not significantly induced. Overall, melatonin contributes to the secretion of ABA in plants and has a tendency to inhibit the content of SA. It is worth mentioning that the 100 μM melatonin treatment was more conducive to the secretion of IAA. To sum up, this experiment proves that melatonin has a dose effect in alleviating stress.
