Genetiği değiştirilmiş bitkiler, kurşunun (Pb) kökten yer üstü kısımlarına translokasyonunu geliştirmek için büyük bir potansiyele sahip olabilir. Transgenik olmayan ( Nicotiana tabacum L. cv. Petit Havana SR1) ve transgenik (p-cV-ChMTII GFP) tütün bitkileri tarafından Pb alımının sağlanması araştırmak için Çin hamsteri metalotiyonin II gezen bir kap deneyi yapıldı . Transgenik ve transgenik olmayan tütün bitkileri, 0, 1000, 2500, 5000 mg Pb kg- 1 ile Pb (NO 3 ) 2 olarak işlenmiş topraklarda yetiştirildi. Kelimede bir büyüme bölümünde 6 hafta boyunca çiçeklenme aşamasına kadar.Bitkilerin büyümesi, klorofil içeriği, mineral besin elementleri ve düşük glutatyon (GSH) bezleri, bitkilerin Pb alım potansiyeli ile birlikte incelenmiştir. Hem transgenik hem de transgenik olmayan bitkiler için Pb uygulamasındaki artışa bağlı olarak yer üstü biyokütle çevrildi aşamalı bir düşüş gözlendi. Yaprak besinlerinin bulaştığı, aşırı Pb işlemlerinden olumsuz etkilenmiştir, bunlardan en büyük düşüşü. Sürgün Pb yüksek derecesi 76.0 mg kg kadar ulaşan -1 transgenik ve 70.9 mg kg -1 transgenik olmayan bitkilerde. Pb alımı, p-cV-ChMTII GFP'nin tütün bitkisine aktarılmasıyla iyileştirildi; ancak, Pb fitoremediasyonunda yeterli değildi.

Experiments were conducted to study the NO3− and Cl− interactions during uptake by burley tobacco (Nicotiana tabacum L., cult Ky 14) and the effects of their interactions on plant composition over long growth periods. Results indicated that NO3− or Cl− inhibited the absorption of the other anion by burley tobacco plants but did not influence the composition of cations. Positive linear relationships were found between NO3− and Cl− levels in solution, and the NO3− and Cl− contents in the plants in the laboratory and greenhouse studies. The inhibition of NO3− by Cl− during accumulation was also evident for tobacco plants grown under field conditions for longer periods. The interaction between NO3− and Cl− appears to be competitive during accumulation by burley tobacco. Competition between NO3− and Cl− during accumulation is proposed to be localized in the leaf cell rather than at the root–media interface.

<p>ABSTRACT<br />High Cl content of tobacco might have negative effect on quality. The study tried to find out correlation between added Phonska fertilizer to rice planted before tobacco on tobacco Cl content. The objective was to determine the effect of added Phonska (10.8% Cl) to rice planted before tobacco on tobacco Cl content and quality. The study was carried out in the area of tobacco in five districts of Jombang, East Java Province from May to November 2012. Collecting data was done using survey method to the tobacco farmers and soil and tobacco samples were collecting from 100 points which were distributed in five districts based on land use map. The results showed that the most tobacco farmers (67%) added Phonska to the rice planted before tobacco. Addition of Phonska each year had caused accumulation of Cl in soil with high level &gt;2% (90%). Based on analysis of variance it was known that tobacco Cl content was strongly influenced by Phonska addition to rice planted before tobacco plants (PPP) and soil Cl content, but not influenced by Phonska as starter to tobacco plants (PPT). The corelation was expressed by equation: leaf Cl = 0.4266 x exponential ((0.367 PPP*) - (0.314 PPT) + (0.388 soil Cl*))*.<br />Keywords: Nicotiana tabacum L., quality, Phonska fertilizers, Cl</p><p> </p><p>HUBUNGAN ANTARA PUPUK PHONSKA PADA PADI DAN KADAR Cl TEMBAKAU DI JOMBANG, JAWA TIMUR</p><p>ABSTRAK<br />Tingginya kadar Cl dalam daun tembakau adalah salah satu penyebab rendahnya mutu tembakau. Cl tembakau bisa berasal dari pemupukan seperti Phonska (10,8% Cl) atau dari tanah. Penelitian observasi ini bertujuan untuk mengetahui pengaruh penggunaan pupuk Phonska (10,8% Cl) pada padi terhadap mutu dan kadar Cl tembakau yang ditanam setelah padi. Kegiatan penelitian dilaksanakan pada areal penghasil tembakau di lima kecamatan Kabupaten Jombang mulai bulan Mei sampai Nopember 2012. Survei pendahuluan untuk penentuan 100 satuan titik lokasi dilakukan secara proporsional yaitu berdasarkan prosentase terhadap luas areal tanaman tembakau dan mewakili bekas lahan padi yang tidak dipupuk dan yang dipupuk Phonska dari lima kecamatan berdasarkan peta penggunaan lahan. Pengumpulan data dilakukan dengan menggunakan metode survei, yaitu wawancara petani tembakau tentang penggunaan pupuk phonska pada padi dan tembakau, pengambilan sampel tanah dan daun tembakau. Penilaian mutu/harga tembakau oleh grader pabrik rokok. Sampel tanah dan daun tembakau dianalisis kadar Cl di Laboratorium Mutu Hasil Balai Penelitian Tanaman Pemanis dan Serat. Data hasil pengamatan dianalisis secara deskriptif yaitu klasifikasi berdasarkan persentase kejadian. Untuk  mengetahui hubungan atau pengaruh antar variabel dilakukan analisis regresi menggunakan program SPSS. Dari hasil survei diketahui bahwasebagian besar petani (67%) menggunakan pupuk Phonska untuk tanaman padi sebelum tembakau dan akumulasi Cl tanah tergolong tinggi &gt;2% (90%). Dari hasil analisis sidik ragam diketahui bahwa kadar Cl daun tembakau sangat dipengaruhi oleh pemupukan Phonska pada padi sebelum tanaman tembakau (PPP) dan kadar Cl tanah, tetapi tidak dipengaruhi oleh pemupukan Phonska pada Tembakau (PPT) sebagai starter. Hubungan pemupukan Phonska,  Cl tanah, dan Cl daun tembakau tersebut diekspresikan dengan model persamaan : Cl daun = 0,4266 x exponensial ((0,367 PPP*) – (0,314 PPT) + (0,388 Cl tanah*))*.<br />Kata kunci : Nicotiana tabacum L., mutu, pupuk Phonska, Cl</p>
