Salicylic acid (SA) is a plant hormone mainly associated with the induction of defense mechanism in plants, although in the last years there is increasing evidence on the role of SA in plant responses to abiotic stress. We recently reported that an increase in endogenous SA levels are able to counteract the inhibitory effects of several abiotic stress conditions during germination and seedling ...

Aims In this study, we examined the effects of Solidago altissima (hereafter Solidago) and two species in the genus Verbesina, Verbesina virginica and Verbesina occidentalis (hereafter Verbesina), on the structure of an old-field plant community and establishment by an invasive plant species, Lespedeza cuneata (hereafter Lespedeza). Methods We removed Solidago, Verbesina and both Solidago and V...

Ecosystems that are heavily invaded by an exotic species often contain abundant populations of other invasive species. This may reflect shared responses to a common factor, but may also reflect positive interactions among these exotic species. Armand Bayou (Pasadena, TX) is one such ecosystem where multiple species of invasive aquatic plants are common. We used this system to investigate whethe...

BACKGROUND AND AIMS Success during the early stages of the life-history of alien plants is essential for invasion to occur. The reproductive components of plant invaders have mostly been studied in species reproducing sexually but little is known about invaders that depend exclusively on vegetative reproduction. In this paper, the importance of the different recruitment stages on population gro...

Establishment of new plant varieties is getting important due to tremendous increase in population and changes in the human food behaviors. This leads towards the demand of new techniques and varieties in plant productions. Therefore some of the wild species and some other important plants species are in the extinction condition. Germplasm conservation of some of the important species is essent...

This chapter covers the advances in establishment and optimization of brassinoste‐ roids (BRs) in the alleviation of abiotic stresses such as water, salinity, temperature, and heavy metals in plant system, especially roots. Plant roots regulate their develop‐ mental and physiological processes in response to various internal and external stim‐ uli. Studies are in progress to improve plant root ...
