Biology and management of freesia flower specking caused by Botrytis cinerea
No full textThere is no published research regarding postharvest infection of freesia flowers
by Botrytis cinerea. Although, infection problems have concerned freesia growers and
wholesalers in recent years. The overall objectives of this study were firstly to evaluate
the factors affecting B. cinerea postharvest disease establishment and secondly to
evaluate a range of novel potential treatments to reduce postharvest freesia infection.
These treatment options include plant activators such as acibenzolar-S-methyl and methyl
jasmonate and biotic (Aureobasidium pullulans) and abiotic (UV-C irradiation)
biological/elicitors agents.
Research was undertaken in an attempt to explain the variation in B. cinerea
incidence on cut freesia flowers as noted by the UK importer Zwetsloots & Sons Ltd. in
2000. Higher monthly rejections of freesia flower stems throughout 2000 due to B.
cinerea infection were recorded during spring (April-May), early summer (June) and
autumn (October). Comparatively higher proportions of rejected freesia stems were
associated with glasshouse temperatures ranging from 13-17°C.
In the presence of B. cinerea inoculum on freesia petal surface, temperature was
not a limiting factor for disease establishment. Incubation of artificially inoculated
freesia flowers at 12°C resulted in overall higher disease severity and lesion numbers
compared to flowers incubated at 5 or 20°C. In contrast, relative humidity was the most
important factor for postharvest infection by B. cinerea.
Elicitor based strategies for IPM using the potent activator acibenzolar provided
limited protection of freesia flowers against B. cinerea when applied postharvest.
Acibenzolar significantly reduced disease severity, lesion numbers and lesion diameters
compared to the untreated control when applied at 0.15 g A. 1. U1.
Methyl jasmonate (MeJA) applied as gas, pulse and spray generally suppressed B.
cinerea disease on cut freesia flowers. Disease severity, lesion numbers and lesion
diameters of flowers gassed with 0.1 μL MeJA L"' were reduced by 56,43 and 37%,
respectively compared to untreated control flowers. Gaseous MeJA treated freesia
flowers at 0.1 μL L"1 increased PPO activity by 57% compared to untreated controls 24h
after MeJA treatment. After 36h of incubation at 20°C, disease severity, lesion numbers and lesion diameters of gaseous MeJA treated flowers were reduced by 68,56 and 50%,
respectively, compared to the untreated controls. However, PAL activity in MeJA treated
freesia flowers did not decrease significantly over time compared to untreated control 12h
post-inoculation and thereafter. These findings suggest that MeJA treatment might
suppress the action of PAL in the phenylpropanoid pathway and consequently block SA
production.
UV-C irradiation might be used in an integrated postharvest disease management
program for freesia flowers. UV-C irradiation after artificial inoculation resulted in
markedly reduced B. cinerea disease severity scores and lesion numbers. In detail, UV-C
irradiation of cut freesia flowers with 0.5,1,2.5 and 5 kJ m''` reduced disease severity by
up to 44,70,74 and 59% and lesion numbers by up to 37,62,68 and 60%, respectively.
UV-C irradiation at 1 kJ M-2 before artificial inoculation slightly reduced disease severity
and lesion numbers possibly by inducing defence responses. However, the limited
disease suppression suggested that apparently B. cinerea could overcome the UV-C
induced effect.
The effect of preharvest treatments on freesia crops with acibenzolar was
investigated in glasshouse trials in view to suppress postharvest B. cinerea infection via
SAR induction. Acibenzolar was effective in selected treatments and conditions.
Disease pressure varied over the 3 years and over varieties tested. However, it was
unclear whether acibenzolar induced systemic and/or local defence responses. The latter
was supported by biochemical investigations in 2001 which suggested that acibenzolar
did not induce PAL activity.
In contrast, preharvest MeJA treatment resulted in markedly systemic protection
of treated flowers compared to untreated ones. MeJA efficacy was dependent on variety
and on postharvest incubation temperatures. Disease severity, lesion numbers and lesion
diameters on MeJA treated freesia var. `Dukaat' flowers incubated at 20°C were reduced
by 56,61, and 49% compared to controls, respectively. Also, disease severity, lesion
numbers and lesion diameters on MeJA treated `Cote d'Azur' flowers incubated at 20°C
were reduced by 36,26, and 49% compared to controls, respectively

The Graphic Icons of Anastasios of Sinai
No full textThe interactions between Christians and Muslims have long fascinated historians, theologians, and scholars from several other disciplines. In recent decades, a great deal of research has been directed towards the development of Islam in relation to the Byzantine Empire. Archeological studies have delivered fresh insight regarding the tolerance of Christianity by the early Muslims. Numismatic research has demonstrated a strong relation between the political tactics of Byzantium and the Islamic Caliphate. Careful scrutiny of primary texts has also suggested that the early Muslims were far more similar to Jews and Christians than has been previously allowed. This similarity conflates many religious practices, often blurring the view of neat, linear, cause-and-affect progressions.
The first intentional effort of Muslims to distinguish themselves from the other religious entities in the Levant occurs at the end of the seventh century, a period of years that curiously coincide with a particular theological incident. This incident was pioneered by a monk named Anastasios, who resided at the Monastery of St. Catherine at the base of Mt. Sinai. Until now, Anastasios’ work has primary been studied for its value in elucidating internal Christian dialogues and concerns. Some have also analyzed the references to Islam in the writings of Anastasios, but such efforts have been mostly peripheral.
This paper aims to reach a better understanding of the early Islamic interactions with Christianity by considering the specific theological implications of Anastasios’ work. One of the most extraordinary aspects of Anastasios’ work involves the usage of religious images (icons). Anastasios does not merely offer a modified theological argument in the mold of previous theologians, but pairs his convictions with an explicit call for a new breed of icons. These Crucifix icons are the first to depict Jesus as completely dead, and will be carefully studied in the following pages. After consideration of these icons, this paper will reach a climax in the corollary assessment of the Iconoclastic Controversy. In Byzantium, this controversy lasted from approximately 726 – 843, but was heralded by a slightly earlier controversy in the Islamic world. Although many scholars have attempted to delineate the relation between these iconoclastic movements, none have yet provided a thoroughly conclusive explanation.
Here, an attempt will be made to present a plausible scenario for understanding the multifaceted features of the Iconoclastic Controversy. This will involve a considerable review of the theological debates that precede the Iconoclastic Controversy so that the controversy itself can be better apprehended. Likewise, a thorough survey of icons and their development will establish the backdrop against which Anastasios’ radical icons can be juxtaposed. In order to properly decipher the Islamic reactions toward Anastasios’ icons, a critical appraisal of Islam’s beginnings will also be conducted.
After an adequate contextual foundation has been laid, the specific work of Anastasios will be systematically discussed. As mentioned already, special focus will be given to the theological consequences of Anastasios’ work. It is vital to consider how Anastasios’ iconographical innovation was received by Muslims, but also by Monophysites and Chalcedonian Christians. During this process, several questions should be kept in mind: (1) What motivated Anastasios to depict what no other Christian artist had dared depict before him? (2) As a monk living under the rule of the Islamic Caliphate, how did Anastasios view the beliefs of his Muslim neighbors? (3) If Christians offended Muslims with their icons, why is it that much of Byzantium seems to react in the same way? In the course of considering Anastasios’ work, several persuasive answers to these questions will be proposed.
The final stage of this thesis will seek to determine the impact of Anastasios’ upon the immediate Christian posterity. Because the mandates of iconoclasm frequently demanded the destruction of icons, there is a noticeable dearth of pertinent artifacts available for scrutiny. Nonetheless, a glimpse of pristine iconographic thought during the Iconoclasm can be achieved due to the asylum that was provided by several monasteries in the Levant. These religious sanctuaries managed the exceptional feat of isolating monks from both their Islamic overlords and the more distant Byzantine authorities. The writings of John Damascene serve as an impeccable example of this phenomenon and also link his work to that of Anastasios. John, like all other Christian writers of history, was influenced by at least one specific theological legacy; by a stand of thinking that inspired him to adamantly oppose the emperor and many of his immediate Christian neighbors. This strand of thinking is of supreme importance, and although it feature multiple offshoots and divisions, it will be presented as a primary impetus of the Iconoclastic Controversy

Albanski nadškof Anastasios
No full textIn recent years, several disputes between Orthodox churches over jurisdictional and politico-ideological matters have raised questions about Eastern Orthodoxy’s commitment to peace. However, as a Christian denomination, Eastern Orthodoxy is theologically centred around the fundamental Christian values of love and peace. To illustrate how Eastern Orthodoxy can inspire a life devoted to peace, this article focuses on Anastasios Yannoulatos (b. 1929), the current Archbishop of the Albanian Orthodox Church, whose life constitutes a concrete Eastern Orthodox example of peace. Firstly, Archbishop Anastasios’ life story and core theological ideas are presented, and secondly, his contribution to peace is briefly highlighted.V zadnjih letih je več sporov med pravoslavnimi cerkvami glede pristojnosti in politično-ideoloških vprašanj sprožilo vprašanja o zavezanosti vzhodnega pravoslavja miru. Vendar pa je vzhodno pravoslavje kot krščanska veroizpoved teološko osredotočeno na temeljne krščanske vrednote ljubezni in miru. Da bi ponazorili, kako lahko vzhodno pravoslavje navdihuje življenje, posvečeno miru, se ta članek osredotoča na Anastasiosa Yannoulatosa (r. 1929), sedanjega nadškofa albanske pravoslavne cerkve, katerega življenje je konkreten vzhodnopravoslavni primer miru. Najprej so predstavljeni življenjska zgodba in temeljne teološke ideje nadškofa Anastasiosa, nato pa na kratko še njegov prispevek k miru
