Effects of brassinosteroids on prosperity of Scots pine seedlings

The aim of the experiment was to improve seed quality of harvested soybean seed by pre-sowing seed treatment with biologically active compounds Lignohumate B (mixture of humic and fulvic acids), Lexin (mixture of humic and fulvic acids enriched by auxins), brassinosteroid (synthetic analogue of natural 24 epibrassinolide) and socalled complete seed treatment (mixture of saturated solution of sucrose, Lexin, Maxim XL 035 FS fungicide of Syngenta and adjuvant on the base of pinolene). Four-year experiments proved positive influence of all treatments to seed parameters (laboratory germination, seed vigour (AA test), field emergence and thousand seed weight).

“…In the case of plantation established on abandoned agricultural land in the locality of Truba (Kostelec nad Černými lesy), a positive effect on mortality was observed in the European beech plantation (Gallo et al 2017). On the contrary, in the same locality, the effect on mortality and growth performance of Scots pine plantation was significantly negative (Nováková et al 2014). Furthermore, the effect of brassinosteroids in overcoming stress during germination was investigated.…”

Fertilization and liming began to be used in forestry at the beginning of the 20th century in order to increase growth, for improvement of health status or higher resistance to biotic and abiotic factors. The review summarizes results of 48 studies of forest fertilization, nutrition and liming published in scientific journals by authors of Department of Silviculture in Prague over the past more than 20 years. They deal mainly with monitoring of the effect of fertilization and liming applied during planting or shortly after planting of 18 tree species. Moreover, the results of fertilization in older stands are presented. Separate chapters deal with enhancing substrates (soil conditioners and phytohormones). All forest vegetation ranges are covered, from lowland forests to the subalpine belt of grass vegetation in 11 Natural Forest Areas. Forest fertilizing and liming proved beneficial according to most of the studies. The use of fertilizers can be detected in soils after decades. On the other hand, only in a minority of cases was fertilization reflected in the chemistry of the assimilation apparatus and other parts of the trees for a longer period. The main positive effect of fertilization and liming was increase of tree growth and foliation and decrease of mortality and yellowing symptoms. Inconsistent results were documented in some cases, especially for brassinosteroids and alginite compared to good results in slow release fertilizer done by spot-application. The type of product, concentration, time and method of application play an important role in the appropriate use of fertilization and liming.

“…Brassinosteroids (BRs) as a member of phytosteroidal hormones [11] are known as a new application of plant hormones that belong to the polyhydroxy steroidal group [52][53]. Among the 70 BRs that exist in plants, three types, including 24-epibrassinolide, 28-homobrassinolide and brassinolide, have been underinvestigated in regard to their role in the plant growth and development process because they have been identified as top bioactive brassinosteroids [52][53][54]. BRs play an important role in many growth processes in plants, including the growth of fruit, flowers, pollen, seeds and fiber, as well as rhizogenesis, abscission, and senescence.…”

In addition to regulating plant growth and development, phytohormones play an essential role in the response to abiotic and biotic stress-especially heavy metal stress. In response to environmental stressors, phytohormones act as signaling molecules in both exogenous and endogenous signaling pathways. In parts of the rhizosphere, phytohormones have an exogenous role, and when regulating plant growth and development, they have an endogenous role. Phytohormones and their associated signaling pathway network are involved in plant responses to heavy metal stress. These molecules can improve the plant defense system by increasing antioxidant enzyme activity and degrading lipoperoxidation and H 2 O 2. Phytohormones are divided into classical phytohormones such as auxins, ethylene, gibberellins, and cytokinins, that have been investigated for many years and the new members, such as jasmonates, brassinosteroids, and strigolactones, which have been little studied. In this review article, we investigated the main mechanisms involved in the amelioration of heavy metals by the three new phytohormones to provide more knowledge about their detoxification mechanisms.
