The effects of pulse treatment with gibberellin A3 (GA3), silveT thiosulfate complex (STS), and with or without sucrose on chlorophyll degTadation and vase life of cut flowers of Narcissus tazetta var. chinensis were investigated. The 20-hr pulsing treatment with STS extended the vase life of cut fiowers of IVL tazetta var. chinensis, Pulse treatments with GA3 delayed degradation of chlorophyll...

Treatment of daffodil (Narcissus pseudonarcissus) bulbs in a 0.37% formaldehyde water solution at 44 C for 240 minutes is a standard practice in California for management of the stem and bulb nematode, Ditylenchus dipsaci. Recent concern over the safety of formaldehyde and growers' requests for a shorter treatment time prompted a reevaluation of the procedure. The time (Y, in minutes) required ...

Placement of a scatter cone at the center of the secondary of a Cassegrain telescope greatly reduces Nareissus reflection. To calculate the remaining Narcissus reflection, a time-consuming physical optics code/such as GRASP8 is often used to model the effects of reflection and diffraction. Fortunately, the Cassegrain geometry is sufficiently simple that a combination of theoretical analysis and...

Pepper yellow mosaic virus on Petunia hybrida, bean Viola odorata and Narcissus stripe cyclamineus were identified in Brazil using RT-PCR. Serology, mechanical transmission, host range, electron microscopy used to study the viruses further.

This article surveys the botanical composition of 40 Muslim graveyards in northern Israel, accompanied by an ethnobotanical study of the folkloristic traditions of the use of these plants in cemeteries. Three groups of plants were found to be repeated systematically and were also recognized for their ritual importance: aromatics herbs (especially Salvia fruticosa and Rosmarinus officinalis), wh...

In this study, we sequenced the complete mitochondrial genome of Eligma narcissus and compared it with 18 other lepidopteran species. The mitochondrial genome (mitogenome) was a circular molecule of 15,376 bp containing 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, two ribosomal RNA (rRNA) genes and an adenine (A) + thymine (T) - rich region. The positive AT skew (0.007) indicat...
