A Review On Strong Impacts Of Thermal Stress On Plants Physiology, Agricultural Yield; And Timely Adaptation In Plants To Heat Stress, Alam Sher, Yasmeen Asghar, Abdul Qayum, Muhammad Shabaz, Fatima Kiran, Laraib Arshad, Nadia Mehdi, Uzma Bibi, Shema Iqbal, Zainab Bibi, Rashna Anjum, Humaira Rasool, Javeria Mazher

Journal of Bioresource Management

In this review, we checked the harsh influence of high temperature or heat stress on plant metabolism and crop yield. Plants can bear a minimum range of temperature; temperature more than this optimum range comes in the term of heat stress. Climate changes increase the number and severity of heat waves that reduced the development of plants and resulted in the death of the entire plant. Heat stress is a major stressful environment that destroys plant growth, biochemical reactions, and the yield of crops across the world. High-temperature influences many physiological and chemical reactions in plants. HS is now a …

Tree Biomass – A Fragile Carbon Storage In Old-Growth Birch And Aspen Stands In Hemiboreal Latvia, Laura Ķēniņa, Didzis Elferts, Ieva Jaunslaviete, Endijs Bāders, Guntars Šņepsts, Āris Jansons

Aspen Bibliography

Birch (Betula pendula Roth, Betula pubescens Ehrh.) and European aspen (Populus tremula L.) stands dominate the deciduous forests of Northern Europe. Due to increasing forest protections, more deciduous stands will reach the old-growth stage. Thus, data on the carbon storage potential in such areas are essential. We aimed to establish a benchmark for carbon stocks of the main carbon pools in old-growth deciduous hemiboreal stands. Carbon pools were calculated from measurements in forty old-growth (104–148 years-old) deciduous stands in forests on fertile mineral soil. The carbon stock in these stands is distributed across tree biomass (~ 60%), mineral soil (~ …
