    Notes: [Auszug] Barrick and Peake1-3 have derived the scattering properties of a surface that is "slightly rough", the wave amplitudes being less than the radar wavelength. The sea surface is always slightly rough to hf radar (? = 10-100 m) and often to vhf (1-10 m). Their procedure matches incident and reflected ...

    Description / Table of Contents: Samenvatting In een voorgaande publikatie werd gesuggereerd dat kernrot ontstaat door een combinatie van faktoren. De aard ervan was tot nu toe onbekend. Om deze faktoren te identificeren zijn het ziektesyndroom en de bewaaromstandigheden verder geanalyseerd. Enkele relaties konden worden vastgesteld, die het opstellen van een verklaringshypothese mogelijk maken. Deze relaties zijn: 1. Bij ‘White Sail’ komt kernrot voor als de bollen worden bewaard in doosjes waarin ook bollen voorkomen die aangetast zijn doorFusarium oxysporum f. tulipae (‘zure bollen’); 2. Knoppen met symptomen van kernrot zijn aan de toppen open. Dit komt zowel bij ‘White Sail’ en ’Red Champion’ voor als bij ’Rose Copland’. Als deze afwijking in sterke mate optreedt groeien de meeldraden door de opening aan de top van de knop; 3. Open knoppen komen bij ‘White Sail’ alleen voor in doosjes waarin ook ‘zure bollen’ voorkomen. Bij ‘Red Champion’ kan dit verschijnsel behalve door bewaring in doosjes samen met ‘zure bollen’, ook ontstaan tengevolge van hogere bewaartemperaturen (20–23°C). Bij ‘Rose Copland’ komen open knoppen slechts bij uitzondering voor; 4. In knoppen met symptomen van kernrot komen bijna steeds mijten voor; 5. In doosjes waarin ‘zure bollen’ voorkomen, is ethyleen aangetoond in concentraties variërend van 0 tot 23 dpm. Op grond van bovenstaande relaties is de hypothese opgesteld dat kernrot alleen dan ontstaat, wanneer mijten tot in de bloemknoppen kunnen doordringen en de meeldraden kunnen bereiken. Voorwaarde hiervoor is de aanwezigheid van een opening in de top van de knop. Ethyleen uit metFusarium besmette bollen is waarschijnlijk het werkzame agens bij het ontstaan van open knoppen in ‘White Sail’ en ‘Red Champion’, onder omstandigheden van slechte ventilatie. Bij ‘Red Champion’ kan het verschijnsel ook bij goede ventilatie en dan tengevolge van hoge bewaartemperaturen ontstaan. Resultaten van verder onderzoek die de hypothese bevestigen, zullen in een volgende publikatie worden beschreven.
    Notes: Abstract The syndrome of bud necrosis, a storage disease of tulips, is analysed and relationships between several phenomena are described: 1. In ‘White Sail’, bud necrosis occurred in cardboard boxes only when bulbs infected withFusarium oxysporum f. tulipae were present. 2. Buds with symptoms of bud necrosis were open at the tip. 3. Whereas in ‘White Sail’, open buds occurred in boxes only whenFusarium-infected bulbs were present, in ‘Red Champion’, open buds occurred also in well-ventilated open trays with wire-gauze bottoms stored at higher temperatures but withoutFusarium-infected bulbs. In ‘Rose Copland’, open buds were only found exceptionally. 4. In buds with symptoms of bud necrosis, mites were almost always present. 5. In boxes in whichFusarium-infected bulbs were present, ethylene concentrations up to 23 ppm were found. On the basis of these findings it seems highly probable that bud necrosis develops only if mites penetrate into the buds and reach the stamens. A prerequisite for penetration is the presence of a pore in the bud tip. Ethylene, emanated byFusarium-infected bulbs or from other sources and accumulating under conditions of poor ventilation, is probably the direct cause of open buds. In ‘Red Champion’, however, this aberration can also be caused by higher storage temperatures even with good ventilation. In a subsequent paper proof of this hypothesis will be presented.

    Description / Table of Contents: Samenvatting Proeven toonden aan dat kernrot in tulpebollen wordt veroorzaakt door mijten (Rhizoglyphus echinopus Fumouze & Robin enTyrophagus spp.) als deze tijdens de bewaring in de bloemknoppen binnendringen (Tabel 2 en 3). Dit konden mijten alleen bij knoppen die aan de top open waren; normaal zijn de knoppen gesloten. Open knoppen ontstonden door blootstelling van de bollen aan ethyleen (3 dpm) bij 20°C vlak na het rooien (Tabel 1 en Fig. 2) en bij bollen van ‘Red Champion’ ook door bewaring bij hoge temperaturen (20 tot 23°C) in een ethyleen-vrije atmosfeer. Dit laatste berustte op een afwijkende differentiatie in de top van de pas aangelegde bladeren (Fig. 3). Ethyleen kon open knoppen doen ontstaan, doordat de lengtegroei van de jonge bladeren sterker werd geremd dan die van de meeldraden (Fig. 1). De snellere groei van de binnenste delen van de knop resulteerde dan in open knoppen. Het verschil in gevoeligheid van beide organen voor ethyleen was het grootst vaak na het rooien en nam af gedurende de bewaring. Later in het seizoen (na augustus) was de remming van meeldraden en jonge bladeren gelijk (100%) en ontstonden geen open knoppen meer. Ethyleen veroorzaakte toen verdroging van de bloemknoppen. De door ethyleen geïnduceerde groeiremming was ten dele reversibel. De groei van de jonge bladeren herstelde gedeeltelijk; de groei van de meeldraden geheel, tenzij verdroging van deze organen had plaats gehad als gevolg van blootstelling aan ethyleen laat in het seizoen. Door het verschil in reversibiliteit van de groeiremming van meeldraden en loofbladen kan de toename van de mate van knopafwijking tijdens verdere bewaring na de toediening van ethyleen verklaard worden (Tabel 1). De ethyleenafgifte van bollen die metFusarium oxysporum f.tulipae waren geïnfecteerd, is gemeten. De geproduceerde hoeveelheden ethyleen bleken afhankelijk te zijn van de bewaartemperatuur. Gemiddeld werd de grootste hoeveelheid gevonden bij 20°C, namelijk: 140 μl per dag per bol (Fig. 4). Deze hoeveelheid blijkt voldoende te zijn om in slecht geventileerde ruimten bij bollen die niet doorFusarium zijn aangetast, bovengenoemde abnormale groei te veroorzaken.
    Notes: Abstract Experiments demonstrated that bud necrosis in tulip bulbs is caused by mites that penetrate the flower bud during storage. This penetration is only possible if the buds, which are normally closed, are open at their tips. Such buds were found after administration of ethylene (3 ppm) during storage at 20°C shortly after lifting and in ‘Red Champion’ also after storage at higher temperatures (20 to 23°C) in ethylene-free atmospheres. Open buds, caused by ethylene, resulted from unequal growth inhibition of the young leaves and stamens. The difference in sensitivity of both organs to ethylene decreased during storage. later on, the growth inhibition of stamens and leaves became equal, and the buds remained closed. Then ethylene caused blasting of the flower buds. Open buds in ‘Red Champion’, caused by higher storage temperatures, resulted from aberrant differentiation of the tips of the young leaves. The production of ethylene by tulip bulbs infected withFusarium oxysporum f.tulipae was measured and proved to be sufficiently high to cause open buds in non-infected bulbs stored in the same room if ventilation is not adequate. The highest production of ethylene, averaging 140 μl/24 h/bulb was found at a storage temperature of 20°C.
