the present research was carried out under hydroponic culture to evaluate the interaction between salicylic acid (sa), nickel (ni) on vegetative and reproductive growth of strawberry plants as a factorial experiment in a completely randomized design. well-rooted daughter plants of pajaro cultivar, were potted in 3 l plastic pots and were sprayed with sa at concentrations of 0, 1, 2 and 3 mm and...

(-)-Cannabidiol (CBD) is a cannabinoid, which has unique pharmacological and biological activities.The aim of this study was to determine the CBD, cannabidiolic (CBDA), canabigerolic acids (CBGA) content in parts industrial hemp that are possible waste material production fiber, could be used for CBD extraction. Two varieties were sampled at full-flowering stage, ripening stage. The lyophilised...

When insect activity is limited at low temperature, birds may be comparatively more important pollinators than insects for flowering plants. It has been thought that many large-flowered Rhododendron species are pollinated by local birds in the Himalayan regions because most of these species flower in spring at high elevation with cool atmospheric temperature. However, experimental evidence for ...

In Arabidopsis, treating shoots with uniconazole can result in enhanced primary root elongation and bolting delay. Uniconazole spraying has become an important cultivation technique in controlling the flowering and improving the fruit-setting of litchi. However, the mechanism by which uniconazole regulates the complicated developmental processes in litchi remains unclear. This study aimed to de...

BACKGROUND AND AIMS Plant species typical of cold and warm habitats differ in a suite of morpho-physio-phenological traits, although their evolutionary routes have been poorly explored. Here, it is advocated that traits typical of different climate regimes can be largely driven by contrasting branch architectures. This is explored within Saxifraga. First, an investigation was carried out to det...

Flowering plants have developed many ways to arrange their flowers. A flower-bearing branch or system of branches is called an inflorescence. The number of flowers that an inflorescence contains ranges from a single flower to endless flower-clusters. Over the past centuries, botanists have classified inflorescences based on their morphology, which has led to an unfortunate maze of complex botan...

We report on a phylogenetic analysis of correlations between the occurrence of dioecy and several ecological and life-history attributes: tropical distribution, woody growth form, abiotic pollination, small inconspicuous flowers and inflorescences, many-flowered inflorescences and fleshy fruits. Various hypotheses have been proposed to explain why associations occur between dioecy and several o...
