Narcissus: Visualising Information

It is becoming increasingly important that support is provided for users who are dealing with complex information spaces. The need is driven by the growing number of domains where there is a requirement for users to understand, navigate and manipulate large sets of computer based data; by the increasing size and complexity of this information and by the pressures to use this information efficie...

Comparison of the Polypeptide Complement of Different Plastid Types and Mitochondria of Narcissus pseudonarcissus

The protein complement of chloroplasts, prochromoplasts, chromoplasts, and mitochondria of the daffodil (Narcissus pseudonarcissus) has been investigated comparatively by gel electro­ phoresis. Mitochondria do not share common proteins with plastids. On the other hand, there is a broad overlap of the protein complement of the three plastid types investigated, in spite of their different fine st...

Interaction Effect of Salicylic Acid and Putrescine on Vase life of Cut Narcissus Flowers

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...

Identification of genes associated with perianth senescence in Daffodil (Narcissus pseudonarcissus

We used a PCR-based subtractive procedure to isolate genes that increased in abundance in the perianth of incipiently senescent daffodil (Narcissus pseudonarcissus L. ‘Dutch Master’) flowers. Using RNA gel blot analysis we confirmed that 18 of the transcripts were senescence-associated. A number of these have homologs in previously-studied senescing floral and leaf tissue systems (cysteine prot...
