in order to study the effects of silver thiosulfate (0.02, 0.05, 0.1 and 0.2 mm), humic acid (100, 500 and 1000 mg l-1), nano silver (5, 10, 25 mg l-1), salisilicacid (1, 2 and 4 mm) and sucrose (1%, 2.5% and 5%) on the vase life and some qualitative characteristics of cut narcissus var duch master floweres, two expriments were counducted in postharvest laboratory of mohaghegh ardabili universi...

The effects of salicylic acid (SA) and Putrescine (Put), on cut Narcissus was studied. SA (0, 100 and 200 mg l-1) and Put (0, 150 and 300 mg l-1), their combinations were tested as preservative mixture. This study was conducted in a factorial experiment with complete randomized design on 108 Narcissus cut flowers in horticulture laboratory of agriculture faculty of Islamic...

UNLABELLED PREMISE OF THE STUDY Microsatellite loci from a genomic library of the species Narcissus papyraceus were optimized and characterized for studies of population genetics. • METHODS AND RESULTS Eleven markers that were successfully amplified showed polymorphism when tested on 50 individuals from two populations in southern Spain and northern Morocco. Overall, the number of alleles ...

Abstract The Narcissus pseudonarcissus cv. Carlton contains Amaryllidaceae alkaloids namely galanthamine, lycorine, homolycorine, narciclasine, which are noted for their pharmaceutical properties such as the treatment of early to mid-stage Alzheimer's diseases, cancer, tumor etc. Alkaloid biosynthesis using plant in vitro systems has been considered a tool drug discovery and pathways starting b...

A simple RNA isolation method based on hot borate and proteinase K was used to extract high-quality RNA from petals of daffodils (Narcissus pseudonarcissus L. 'Dutch Master'). The method was adapted from the isolation technique described by Wan and Wilkins (1994). A single isopropanol precipitation and ethanol wash replaced all the second day steps of the Wan and Wilkins procedure. The RNA isol...

Many secondary plant compounds are synthesized in response to stressed growing conditions. We tested the feasibility of exploiting this feature in a novel strategy for the commercial production of the plant alkaloid galanthamine. Experimental lines of Narcissus pseudonarcissus were established under marginal upland permanent pasture at four different sites. Over 80% of bulbs successfully establ...

A study has been made of the optical performance to be expected from an Antarctic Ritchey Chrétien telescope with a 2 m diameter primary mirror imaging directly onto a detector array in the K and L infrared windows. Near diffraction limited performance is provided across a flat 30 arcmin diameter field by compensating the astigmatism and field curvature with a meniscus lens which also serves as...
