The hypoxia–reoxygenation stress in plants

Silicon alleviates salt stress in pistachio plants

In this work, the effects of silicon (Si) supplementation were studied in pistachio (Pistacia veraL. cv Ahmadaghaii) plants exposed to high salinity stress. Plants were grown in pots undercontrol and salt (EC=15 dS m-1) conditions without or with Si treatment (0.35 g Na2SiO3 Kg-1soil) under field conditions. Salt stress reduced the plants’ growth significantly in both –Si and+Si plants; however...

Abiotic Stress in Plants

Living on the same planet, plants means a lot to us. No matter being taken, as our food or treated with great commercial significance, plants are so indispensable that we have to learn how to protect, make use of, and most important of all, get on well with them. In the first place, what we all understand is: plants are distinguished from us or other animals by being unable to escape from the s...

Abiotic Stress in Plants – Mechanisms

Plants and flooding stress

Floods early this year in Queensland, Australia, received a great deal of attention in the media because they affected a land area the size of Germany and France combined. However, on a world scale this is not exceptional as in some years the land area exposed to flooding is > 17 million km, equal to twice the size of the USA. These dramatic floods occur in all continents of our planet and resu...
