Two new species of Psoralea L. are described: Psoraleaditurnerae A. Bello, C.H. Stirt. & Muasya, sp. nov. and Psoraleavanberkelae C.H. Stirt., A. Bello & Muasya, sp. nov. Psoraleaditurnerae is endemic to the Outeniqua mountains (Camferskloof) and is characterised by a mass of numerous basal shoots out of which emerge 2-3 woody stems up to 2 m tall, 3-foliolate needle-like leaflets at the base o...

The capacity to form flower buds in thin-layer explants was studied in flowering plants of several species, cultivars, and lines of Nicotiana differing in their response to photoperiod. This capacity was found in all biotypes examined and could extend into sepals and corolla. It varied greatly, depending on genotype, source tissue and its developmental stage, and composition of the culture medi...

Plant branching is a key process in the yield elaboration of winter oilseed rape (WOSR). It is also involved in plant tolerance to flower damage because it allows the setting of new fertile inflorescences. Here we characterize the changes in the branching and distribution of the number of pods between primary and secondary inflorescences in response to floral bud clippings. Then we investigate ...

Optimal nutrient management is critical for optimizing flowering, yield, quality and improving soil health. A key approach making chrysanthemum crop cultivation profitable balanced fertigation at the right time. This possible by through drip. The present study was designed in 2019–2021 a model floriculture center, Pantnagar, to investigate response of split application NPK drip on flowering att...

Abstract To demonstrate the impact of planting date and pot shape on Flowering Seed Production Snapdragon plants under various production systems, a factorial experiment using randomized complete block design (RCBD) was carried out in local nursery city Duhok northern Iraq from Jan 10, 2021, to 6, 2022. Each experimental unit had eight pots, for total 92 pots experiment, which 24 units four rep...

The movement and mobilisation of phosphorus in various tissues of banana was studied using P. The isotope was given by pseudostem injection and activity measured in various tissues. It was inferred that the male inflorescence, rhizome, fruit and fruit peduncle are the major nutrient sinks. The activity pattern in different hands showed that the highest activity was in the fourth followed by the...

Purple loosestrife, Lythrum salicaria, has invaded North American wetlands over the last 200 years. A biological control project was started in British Columbia, Canada, in 1993 with the introduction of Galerucella calmariensis, a leaf-feeding beetle of European origin. To evaluate the success of the biological control project in the Lower Mainland of British Columbia, we monitored the defoliat...

Antagonists can play a role in sexual system evolution if tolerance or resistance is sex-dependent. Our understanding of this role will be enhanced by consideration of the effects of antagonists on other plant-animal interactions. This study determined whether the sex morphs of a gynodioecious Fragaria virginiana differ in their susceptibility and response to damage by spittlebugs and whether d...
