We present a miniaturized high-throughput sensor array that will augment biofuel technology by facilitating in situ biochemical measurements upon micrometer-scale surfaces of leaves, stems, or petals. We used semiconductor processing to photopattern Foturan glass wafers and fabricated gold-plated microscopic electrode needles (ElectroNeedles) that pierced 125-mum-thick surfaces without deformation. The 5 x 5 or 10 x 10 arrays of ElectroNeedles can analyze 25 or 100 samples simultaneously, increasing throughput. Each microneedle in the array can also be individually addressed and selectively functionalized using diazonium electrodeposition, conferring multiplexing capability. Our microfabrication is a simple, inexpensive, and rapid alternative to the time-, cost-, and protocol-intense, deep-reactive-ion-etching Bosch process. We validated the system performance by electrochemically detecting p-cresol, a phenolic substrate for laccase, an enzyme that is implicated in lignin degradation and therefore important to biofuels. Our limits of detection (LOD) and quantization (LOQ) for p-cresol were 1.8 and 16microM, respectively, rivaling fluorescence detection (LOD and LOQ = 0.4 and 3microM, respectively). ElectroNeedles are multiplexed, high-throughput, chip-based sensor arrays designed for minimally invasive penetration of plant surfaces, enabling in situ and point-of-test analyses of biofuel-related biochemicals.

“…Bu çalışmada lens solüsyonlarının mikrobiyal aktiviteyi azaltarak su alımını iyileştirdiği aynı zamanda sitrik asidin vazo solüsyonlarının pH değerini önemli ölçüde düşürerek su alımını iyileştirmede önemli rol oynadığı düşünülmektedir. 3.0 ile 5.0 aralığındaki düşük pH değerlerinde hem mikroorganizma aktivitesinin azaldığı hem de su iletiminin daha iyi olduğu belirtilmektedir [30]. Bu çalışmada da negatif kontrol hariç tüm uygulamalar vazo ömrü için ideal pH değeri olarak belirtilen (3.0-5.0) sınırlar içerisinde kalmıştır.…”

Mikrobiyal kontaminasyon nedeniyle vazo ömrü kısalan gerberalarda, antimikrobiyal aktiviteye sahip olduğu bilinen lens solüsyonları ile vazo ömrünün iyileştirilmesi amacıyla yapılan bu çalışmada, bitkisel materyal olarak Gerbera jamesonii Bolus ex Hooker f. türüne ait 'Amulet' çeşidi kullanılmıştır. Vazo solüsyonu olarak; 300 mgL-1 sitrik asit, 10 gL-1 sakkaroz ve 4 farklı dozda (0.5 mlL-1, 1 mlL-1, 2 mlL-1 ve 5 mlL-1) iki farklı lens solüsyonu içeren (Bio True ve Aqua Fresh) solüsyonlar ile yalnız 10gL-1 sakkaroz (negatif kontrol), 300mgL-1 sitrik asit ile 10gL-1 sakkaroz (kontrol) içeren solüsyonlar kullanılmıştır. Bitkilerde çiçek sapı kalınlığı, oransal taze ağırlık, günlük ortalama vazo solüsyonu alımı, toplam vazo solüsyonu alımı, vazo ömrü, vazo solüsyonundaki mikrobiyal aktivite ve vazo solüsyonunun pH değeri belirlenmiştir. Çalışma sonucunda en uzun vazo ömrü 15.22 gün ile 2.0 Bio uygulamasında bulunmuştur. Bu uygulama vazo ömrünü negatif kontrole göre 3.56 gün, kontrole göre 3.02 gün kadar arttırmıştır. 2.0 Aqua ile 2.0 Bio uygulamaları arasında vazo ömrü bakımından istatistiki açıdan bir fark bulunmamakla birlikte, her iki uygulamanın bitkilerde oransal taze ağırlık, günlük ortalama vazo solüsyon alımı ve toplam vazo solüsyon alımını iyileştirdiği ve vazo solüsyonundaki mikrobiyal gelişimi azalttığı saptanmıştır. Çalışma sonuçları göstermiştir ki lens solüsyonları kesme çiçeklerde vazo ömrünü arttırmada kullanılabilecek alternatif koruyucu maddeler olabilir.

“…The use of sugars (sucrose) in holding solution of cut flowers has been extensively studied and has yielded a great amount of success in a variety of cultivars. It also has a negative effect on the process of cell death leading to petal senescence (Chandran et al, 2006). Among the different types of sugars, sucrose has been found to be the most commonly used sugar in prolonging the vase life of cut flowers Nichols (1973).…”

Bougainvillea is a popular ornamental plant in the tropics and sub-tropics of the world. It bursts forth with colorful flowers for the year round if it is planted in the adaptive climate. The ornamental importance of Bougainvillea bract is for the imparting and increasing color effect in the garden. Increasing plantation and beautification of bougainvillea have a scope in drier region and its use in vacant areas as road side plantation, beautification of traffic islands and wide road dividers for its own colorful environment. The study was carried out to investigate the effects of Amino Oxyacetic Acid (AOA) and sucrose on the vase life and senescence of bougainvillea bract. The treatments were used as water control, AOA and sucrose at different concentrations. The decreasing trend of fresh weight was found on the 3rd day and again increased on the 5th day in the case of all treated flowers. The lowest water uptake percentage was found in 4% sucrose and 50 ppm AOA concentration. However, senescence was delayed for 3 days in AOA 50 ppm and 4% sucrose concentration. The vase life of both AOA 50 ppm and 4% sucrose concentration treated-flowers were much longer (4 days) than control compared to the all concentration of sucrose and AOA. The results showed that the best treatment for vase life and delay senescence was AOA 50 ppm and 4% sucrose concentration.
