Authors: BALTA Fikri , ŞEN Seyit Mehmet
Published: October 2023

Amaç: Bu çalışma Tombul (Corylus avellana L.) fındık çeşidinde yongalı göz ve dilcikli aşılama tekniklerinde aşı kaynaşmasının zamana bağlı olarak gelişimini anatomik ve histolojik yönden incelemek amacıyla yürütülmüştür.
Materyal ve Yöntem: Anaç ve kalem materyali olarak Tombul fındık ocaklarından alınan bir yıllık dip sürgünleri kullanılmıştır. Aralık ayının ilk haftasında yongalı göz ve dilcikli aşılar elle yapıldıktan sonra 26-28 C° sıcaklık ve % 70-80 nisbi nem koşullarında 28 gün süreyle bekletilmiştir. Aşılamadan sonra çeşitli dönemlerde aşı yerlerinden rotary mikrotomla 12-20 mikron kalınlığında enine ve boyuna kesitler alınarak mikroskop altında incelenmiştir. İncelemelerde aşı yerlerinde anaç ve kalem tarafından teşekkül eden kallus dokularının durumu, aşı elemanları arasında oluşan nekrotik tabakaların durumu, anaç ile kalemin kaynaşma durumu, kambiyal farklılaşmanın ve yeni vasküler dokuların meydana gelişi ile anaçla kalem arasındaki kambiyal devamlılığının tesisi değerlendirilmiştir.
Araştırma Bulguları: Aşı tekniklerinde anaç ve kalemden kallus oluşumunun kaynaşmanın erken dönemlerinde yavaş gerçekleştiği gözlenmiştir. Bazı aşı örneklerinde aşılama sonrası erken dönemlerde kallus oluşumu zayıf ve yetersiz bulunmuştur. Kallus dokularında ilk kambiyal farklılaşmalara her iki aşı tekniğinde aşılamadan 18 gün sonraki kesitlerde rastlanmıştır. Anaç ile kalem arasında kambiyal devamlılık yongalı göz aşılarında aşılamadan 26 gün ve dilcikli aşılarda 26-32 gün sonra tesis edilmiştir. Aşılamadan 52 gün sonra ve ilerleyen dönemlerde alınan kesitlerde iki aşı tekniğinde de aşı elemanlarının vasküler ilişki içerisinde oldukları gözlenmiştir. Aşı yerlerinde yeni iletim dokularının dilcikli aşılarda yongalı göz aşılarına nazaran daha hızlı meydana geldiği görülmüştür.
Sonuç: Aşı kaynaşmasının gelişimi iki aşı tekniğinde tüm safhalarıyla başarıyla gerçekleşmiştir. Aşılama sonrası erken dönemde oluşan kallus dokusu miktarının kaynaşmanın sonraki gelişimine yön verdiği belirlenmiştir. Bu nedenle, fındık aşılama çalışmalarında erken dönemlerde kallus oluşumunu teşvik edici uygulamaların ve metotların geliştirilmesinin faydalı olacağı değerlendirilmiştir. Anatomik ve histolojik gözlemler, dilcikli aşılarda anaç ve kalem kalınlığının birbirine çok yakın seçilmesinin ve aşı elemanlarının kambiyal bölgelerden iyi çakışmasının kaynaşmanın seyrini olumlu etkilediğini göstermiştir.

Materyal ve Yöntem: Çalışmada, yanıt yüzey yönteminin FCCCD’i, 350-420 nm spektral dalga aralığında maksimum AgNP miktarını elde etmek için üç farklı sentez değişkeni (AgNO3 konsantrasyonu, fındık yaprak ekstraktı/AgNO3 oranı ve reaksiyon süresi)’nin birleşik etkisini araştırmak için kullanılmıştır. Spektral eğri altındaki tahmini alan basit bir orta nokta kuralı kullanılarak Microsoft Office Excel programı yardımı ile hesaplanmıştır. Optimum koşullar altında sentezlenen fındık yaprak ekstraktı-AgNP’leri karakterize etmek için Ultraviyole Görünür (UV-Vis) Spektroskopisi, Fourier Dönüşümlü Kızılötesi (FT-IR) Spektroskopisi ve Transmisyon Elektron Mikroskobu (TEM) kullanılmıştır. AgNP’lerin antifungal etkinliği, altı Phytophthora türü (P. cactorum, P. capsici, P. cinnamomi, P. citrophthora, P. nicotianae ve P. palmivora)’ne karşı in vitro koşullarda denenmiş olup, deneme 6 tekerrürlü olarak yürütülmüştür.

Araştırma Bulguları: UV-Vis spektroskopisi, farklı koşullar altında sentezlenen AgNP’lerin tipik yüzey plazmon rezonans değerlerinin 396 ile 411 nm dalga boyu aralığında değiştiğini ortaya koymuştur. AgNO3 konsantrasyonu, bitki yaprak ekstraktı/AgNO3 oranı ve reaksiyon süresi sırasıyla 5 mM, 0.1 ve 90 saniye olduğunda, araştırılan aralıkta optimum AgNP üretimi elde edilmiştir. FT-IR spektrumu, AgNP’lerin O–H, N–H, C=C, C–N ve C–O gruplarını içerdiğini ve fındık yaprak ekstraktındaki çeşitli bileşiklerin AgNP’lerin sentezinde önemli bir rol oynadığını göstermiştir. TEM analiz sonuçları, AgNP’lerin ortalama 17.48 nm (Gauss uyumu) büyüklüğe sahip küresel formda olduğunu ortaya koymuştur. Yeşil sentezlenen AgNP’lerin P. cactorum, P. capsici, P. cinnamomi, P. citrophthora, P. palmivora ve P. nicotianae’nın misel gelişimini sırasıyla %81.67, %74.80, %73.54, %81.01, %74.50 ve %62.39’a kadar azaltmıştır. Ayrıca AgNP’lerin EC50 değerlerinin 118.58-292.56 µg ml-1 arasında değiştiği ve MIC değerlerinin ise 340 µg ml-1’in üzerinde olduğu belirlenmiştir.

Sonuç: Bu çalışma, fındık yaprak ekstraktı ile sentezlenen AgNP’lerin, Phytophthora türlerinin neden olduğu hastalıkların mücadelesinde kullanılmak üzere daha fazla araştırılması gerektiğini önermektedir.

Published: October 2023

The Ronggojalu spring, with a discharge intensity of more than 3,000L/second, makes it one of the spring with the most significant discharge in Indonesia and is the main supplier of clean water for the City of Probolinggo. From the observation of topographic maps, the existence of this spring forms a lineament with Paras Spring and Sumber Kramat with a direction of Northeast to Southwest. The presence of this lineament can indicate the existence of geological structures that play a role in the formation of spring. In addition, this lineament is in the same direction as the active Probolinggo fault identified by PUSGEN (Pusat Studi Gempa Nasional). This study aims to identify the presence of geological structures in the lineament using satellite gravity data GGMplus (Global Gravity Model) and Remote Sensing. This data is quite efficient and effective in identifying subsurface geological structures. With the SVD (Second Vertical Derivative) analysis, the residual anomaly results from the second derivative value of the Bouger anomaly so that it can show the density contrast value as an indication of the geological structure. From the results of the interpolation of satellite gravity data in the study area, the CBA (Complete Bouguer Anomaly) value range is -16.8 – 4.8 mGal. The analysis of SVD and FHD shows a significant contrast different values along the fault line that passes through the spring. The lineament density processing also shows a weak zone around the fault zone, indicating the continuity in that zone. The existence of a fault under this spring indicates the influence of the fault on the formation of Ronggojalu Spring, Paras Spring, and Keramat Spring. In addition, it is estimated that this fault is a continuation of the active Probolinggo fault.

The achievement target for accelerating TB control in Bali Province and Tabanan Regency has not shown results that meet the target, which can have negative impacts in the form of delays in diagnosis and death in sufferers. This study aims to explore the implementation of tuberculosis control in Tabanan district, Bali Province. The study used a qualitative approach with in-depth interviews and focus group discussions (FGD) with regulators, program implementers, and other stakeholders, with a total of 25 respondents. The result of this study demonstrates that the integration of tuberculosis prevention implementation recommendations from the center to the Tabanan Regency Public Health Center is well established. The local government has allocated funds based on the number of tuberculosis elimination targets achieved in each health center. However, there was a misalignment between the guidelines and their execution in the Public Health Center. This is due to the lack of regional regulations that precisely outline the initiatives described in the center's guidelines. If this trend continues, tuberculosis control efforts will not be as effective as hoped. As a result, complete support is expected due to strong and explicit policies, as well as cross-sector cooperation, to ensure the program's success.
