The Effects Of Brassinosteroid On The Induction Of Biochemical Changes In Lycopersicon Esculentum Under Drought Stress, Mehri Behnamnia, Khosrow Manochehri Kalantari, Jalal Ziaie

Turkish Journal of Botany

Drought stress is considered a restricting factor for plant products; therefore many compounds were applied to minimise the harmful effects of stress. One type of these compounds that have antioxidative characteristics is brassinosteroids. In this experiment, when 4 fully expanded leaves of tomato plants appeared, 24-epibrassinolide (24-EBL) was sprayed onto the leaves at 0.01 and 1 µM concentrations for 3 days with a 1-day interval. Three levels of drought stress (0, 3, and 5 days withholding water) were applied. Thereafter, the effects of brassinosteroids and water stress were investigated on some biochemical and antioxidative parameters of tomato plants. Lipid peroxidation, …

The Effects Of Ultraviolet Radiation On The Contents Of Chlorophyll, Flavonoid, Anthocyanin And Proline In Capsicum Annuum L., Kobra Mahdavian, M. Ghorbanli, Khosrow Manochehri Kalantari Jan 2008

The Effects Of Ultraviolet Radiation On The Contents Of Chlorophyll, Flavonoid, Anthocyanin And Proline In Capsicum Annuum L., Kobra Mahdavian, M. Ghorbanli, Khosrow Manochehri Kalantari

Turkish Journal of Botany

Although ultraviolet radiation is potentially harmful, it is an important component of terrestrial radiation to which plants have been exposed since invading land. Since then, plants have evolved mechanisms to avoid and repair UV radiation damage. Therefore, it is not surprising that photomorphogenic responses to UV-B and UV-C are often assumed to be adaptations to harmful radiation. Most of the compounds accumulated are directly involved in UV-B and UV-C protection: they are either efficient in filtering excess radiation or in scavenging radicals. In this study plants were grown for 5 weeks in controlled environment room. The plants were grown in …

Desert Rocks – A Habitat Which Supports Many Species That Were New To Science In The Last 40 Years, Avinoam Danin Jan 2008

Desert Rocks – A Habitat Which Supports Many Species That Were New To Science In The Last 40 Years, Avinoam Danin

Turkish Journal of Botany

Hard limestone, dolomite, sandstone, and granite constitute, under certain conditions, smooth-faced outcrops in desert areas of SW Asia. This habitat supports the most rare plant species in the desert including most of the desert endemics of Israel, Sinai, and Jordan. The smooth-faced outcrops efficiently contribute runoff water to the rock crevices and events when water is available for plant utilisation take place at a higher frequency than in the other habitats in the desert. In many sites plants are isolated and protected by impermeable rocks from competition from other plants. The rare and special plants found in this habitat include …


Mycota Of South-West Asia, Stephan Helfer Jan 2008

Mycota Of South-West Asia, Stephan Helfer

Turkish Journal of Botany

Fungi are indispensable components of the biota of any region. Their presence and distribution are of paramount importance to flora and fauna, and their ecological function may be responsible for the presence or absence of many other species, particularly plants. Database records on fungi from South-West Asia were consulted to estimate the completeness of mycological exploration of the region. Unsurprisingly, some groups are well represented in certain areas, whereas others are lacking from SW Asian data altogether. In this paper an attempt is made to prioritise both taxonomic and geographical focal points in order to maximise the use of resources …

Floristic Diversity, Conservation Status And Economic Value Of Miniature Sacred Groves In Kanyakumari District, Tamil Nadu, Southern Peninsular India, Selvamony Sukumaran, Solomon Jeeva, Appavoo Deva Sobhana Raj, Doraipandian Kannan

Turkish Journal of Botany

The plant diversity of southern peninsular India has recently been reduced to a great extent due to anthropogenic disturbance and environmental degradation. Disturbance was the major factor responsible for fragmentation of forest vegetation; as a result of this, there is a preponderance of small patches, some of them still preserved as sacred groves because of strong religious beliefs held by the indigenous people of this region. It is thought that one of the prime utilities of sacred groves is the protection and occasional supply of medicinal plants on a sustainable basis. Most of the medicinal plants were confined to these …

Challenges Of In Situ Conservation Of Crop Wild Relatives, Vernon Hilton Heywood Jan 2008

Challenges Of In Situ Conservation Of Crop Wild Relatives, Vernon Hilton Heywood

Turkish Journal of Botany

Crop wild relatives (CWRs) will gain in importance as changing climates put both traditional and advanced cultivars under increasing stress, leading to a need for plant breeding to produce new varieties able to grow under the new climate regimes. Traditionally, the approach to the conservation of CWRs has been ex situ - the collection and maintenance of seed accessions in national, regional, and international germplasm banks, supplemented by field genebanks for species with recalcitrant seeds. More recently the need to maintain CWRs in their natural habitats (in situ) has been advocated. This is very different from on-farm conservation of traditional …

Herbaceous Plant Cover Establishment In A Barren Materials Quarry, Nikolaos Arambatzis, Kitikidou Kyriaki Jan 2008

Herbaceous Plant Cover Establishment In A Barren Materials Quarry, Nikolaos Arambatzis, Kitikidou Kyriaki

Turkish Journal of Botany

The ability to establish cover using grass and legume species without any soil preparation was studied in a barren materials quarry. The biodiversity indexes (Simpson) during the growing season as well as the vegetation cover and composition were measured. The results showed that the established species had a satisfactory cover (up to 87.5%). This means that we can achieve significant soil rehabilitation after mining using herbaceous plant cover and reduce the cost of rehabilitation by cutting the expenses of soil preparation.
