Larutan Pengerdil sang Marinir

DI TANGAN WILLY POERNAWAN DAUN SANSEVIERIA AUBRYTIANA YANG BIASANYA BERUKURAN SETENGAH METER MENJADI 10 CM. DAUN PATULA BERUMUR 6 BULAN YANG LAZIMNYA 15 CM HANYA 2 CM. NILAI JUAL PUN BERLIPAT 6 KALI. ITU BERKAT LARUTAN PENGERDIL YANG DIRAMU SEORANG MARINIR DI SURABAYA. SETIAP PEKAN UJUNG DAUN LIDAH NAGA TERMUDA DIBERI 3 TETES.

Larutan pengerdil itulah yang membawa berkah buat Willy. Tiga bulan terakhir ia menjual 60 pot sansevieria kerdil. Harga per pot Rp150.000, jenis tersebut-aubrytiana, patula, javanica, dan fischeri-biasanya hanya Rp25.000/pot. ‘Saya jual sepaket. Satu pot beserta sebotol larutan pengerdil,’ ujar mantan karyawan perusahaan teknologi informasi itu. Agar sosok tetap kerdil, pembeli mesti rutin meneteskan larutan pada sang lidah naga.

Menurut Willy sansevieria mini disukai karena hemat tempat sehingga cocok buat tanaman meja. Tengok saja Sansevieria cylindrica var patula yang normalnya berukuran 10-15 cm pada umur 6 bulan. ‘Biasanya patula hanya ditanam di halaman,’ kata Willy. Namun, yang dikoleksi Willy justru berdaun pendek, hanya 2 cm. Karena berdaun pendek, bentuk daun terlihat gendut. Willy menanamnya pada pot berdiameter 7 cm.

tanaman hias

Lebih tebal

Pun dengan Sansevieria fischeri. Normalnya panjang daun remaja mencapai 18 cm. Yang diberi larutan pengerdil hanya 5 cm. Susunan daun sama-sama roset. Bedanya pada tanaman normal daun lebih tipis. Yang mini lebih tebal dan cenderung bulat. Daun baru yang muncul tersusun seperti bunga mawar yang masih kuncup.

Perbedaan paling mencolok terlihat pada Sansevieria aubrytiana ‘Tiger’. Lidah jin itu biasanya dijadikan tanaman pagar karena berdaun panjang, 30-70 cm. Saking besarnya kerap disebut pedang-pedangan. Namun, daun lidah naga mini berlurik putih keperakan kepunyaan Willy hanya 10 cm dan lebar 5 cm. Bentuknya menyerupai centong. Susunan daun juga lebih roset. Willy sengaja mengekspos rimpang seukuran umbi bawang merah sehingga tampil semakin unik.

Lantaran ampuh membuat kerdil, larutan sang marinir banyak diperbincangkan kalangan mania sansevieria. Toh komposisi larutan itu ternyata sederhana. ‘Campuran paklobutrazol dan larutan karbit,’ kata Willy. Perbandingannya 1:100. Sayang, Willy enggan memberi tahu konsentrasi yang tepat dan aman buat mengerdilkan. Campuran itu diteteskan dengan pipet pada bakal daun masing-masing 2-3 tetes setiap pekan.

Risiko mati

Menurut Ir Yos Sutiyoso, ahli pupuk di Jakarta, paklobutrazol merupakan senyawa retardan (penghambat, red) yang berfungsi ‘memingsankan’ titik tumbuh sehingga sel berhenti membelah. Zat pengatur tumbuh itu menghambat biosintesis giberelin-hormon yang merangsang pertumbuhan dan perkembangan sel tanaman. Akibatnya daun tumbuh menjadi kerdil. Di bidang pertanian paklobutrazol lazim dipakai untuk menyeragamkan munculnya bunga mangga dan durian.

Campuran karbit pun punya peranan. Menurut Ir Ari Wijayani Purwanto MP, dosen Fisiologi Tumbuhan Fakultas Pertanian Universitas Pembangunan Nasional Veteran Yogyakarta, kalsium yang berasal dari karbit (CaC2) dapat menghambat pertumbuhan tanaman. Kalsium menyebabkan dinding sel menjadi kaku sehingga sulit membelah. Toh, menurut Yos paklobutrazol dan karbit bisa digunakan secara terpisah. Karena peran keduanya sama, maka satu bahan baku pun cukup.

Pengalaman Willy perlakuan dengan larutan pengerdil itu hanya membuat daun tumbuh abnormal sementara. Artinya, bila perlakuan dihentikan pertumbuhan tanaman kembali normal. Agar tanaman tidak stres, usai perlakuan Willy menambahkan vitamin B1 dan pupuk daun dengan dosis 1,5 kali lebih tinggi daripada dosis anjuran dalam kemasan. Tujuannya agar daun yang berukuran mini menjadi lebih tebal dan tampak lebih gendut.

Ari mengingatkan hindari pemberian nitrogen yang berasal dari amonium (NH4). ‘Amonium melemahkan sel tanaman,’ ujarnya. Akibatnya tanaman menjadi rentan sakit. Apalagi tanaman ‘disakiti’ secara berulang. Sebaiknya gunakan nitrogen yang berasal dari nitrat (NO3). Ari pun menyarankan penggunaan paklobutrazol dan karbit dengan meramu sendiri harus berhati-hati. Tanaman bisa mati bila dosis terlalu tinggi. Itu mengacu pada mudahnya mangga dan durian yang merana dan mati setelah diberi paklobutrazol berlebih.

Bakar rimpang

Untuk membuat sansevieria mini Willy juga menggunakan teknik bakar rimpang. Caranya cabut sansevieria dari pot, lalu bersihkan rimpang dari media. Taburkan sesendok teh Urea yang dihaluskan merata ke sekujur rimpang, lalu taburkan sesendok teh kaporit (CaOCl2) sebagai ‘pembakar’. Setelah itu diamkan selama 15 menit, kemudian tanam kembali pada media pasir malang yang telah diayak hingga halus.

Untuk perawatan, siram tanaman sepekan setelah ditanam pada media. Hindari penyiraman basah karena akan melarutkan Urea dan kaporit yang menempel di permukaan rimpang. Cukup berikan air sedikit demi sedikit di permukaan media dekat bibir pot sehingga jauh dari rimpang. Penyiraman hanya dilakukan bila media terlihat kering. Tiga bulan berselang muncul anakan berdaun mini.

Menurut Yos teknik semacam itu intinya sama: membuat tanaman menjadi sakit. Urea yang mengandung amonium berperan melemahkan sel tanaman. Pada kondisi lemah, lalu dihantam pemberian kaporit yang bersifat oksidatif alias ‘membakar’. Akibatnya titik tumbuh pada rimpang rusak.

Rusaknya titik tumbuh membuat generasi baru yang muncul mengalami mutasi. ‘Ukuran sel menjadi lebih kecil,’ kata Ari. Mutasi seperti itu berada pada tingkat kimera alias beberapa kelompok sel, bukan pada tingkat gen. Artinya, hanya menghasilkan tanaman abnormal sementara. Bila ditanam pada media subur, pertumbuhan kembali normal.

Agar mutasi permanen, sebaiknya tanam pada media yang miskin hara. Toh, sansevieria tergolong tanaman bandel. Dengan begitu, sansevieria tetap berukuran mini, tetapi harga maksi. (Imam Wiguna)

Pengerdil solution of the Marines

HANDS IN THE LEAVES Sansevieria WILLY POERNAWAN AUBRYTIANA TYPICALLY HALF VOLT METER TO 10 CM. 6 MONTHS OLD LEAF PATULA commonly ONLY 15 CM 2 CM. JUAL ANY VALUE doubled 6 TIMES. BLESSING IS THE SOLUTION mixed PENGERDIL One Marine DI SURABAYA. EVERY WEEK END OF ALOE LEAVES DRAGONS youngest BEEN 3 drops.

Pengerdil solution that is a blessing for her. The last three months he sold 60 dwarf potted Sansevieria. Price per pot Rp150.000, the type-aubrytiana, patula, javanica, and usually only Rp25.000/pot-fischeri. 'I'm selling a package. One pot and a bottle of solution pengerdil, 'said the former employee's information technology companies. In order to figure remains stunted, the buyer should routinely shed a solution on the dragon's tongue.

According to Willy mini Sansevieria preferred because efficient place making it suitable for the plant table. Just look at the Sansevieria cylindrica patula var a normal size of 10-15 cm at the age of 6 months. 'Usually patula just planted in the yard, "said Willy. However, the collected short leafy Willy actually, only 2 cm. Due to the short leaf, leaf shape look fat. She planted them in pots 7 cm in diameter.

Thicker

Even with Sansevieria fischeri. Normally the length of juvenile leaves reaching 18 cm. A given solution pengerdil only 5 cm. The composition of both leaf rosette. The difference in normal plants the leaves are thinner. The mini is thicker and tends to round. The new leaves that appear arrayed like the roses that are still buds.

The most striking difference seen in the Sansevieria aubrytiana 'Tiger'. The tongue is usually used as a genie hedge plant because of the long-leaved, 30-70 cm. So big is often called the sword-traders. However, the dragon mini aloe leaves silvery-white berlurik belongs to Willy only 10 cm wide and 5 cm. The shape resembles a ladle. The composition is also more rosette leaves. Willy accidentally expose rhizomes so that the size of onion bulbs appear more unique.

Because potent dwarfs, the solution was much discussed among the marines Sansevieria mania. After all, the composition of the solution is surprisingly simple. 'Mixed paklobutrazol and carbide solution,' said Willy. The comparison is 1:100. Unfortunately, she was reluctant to tell the proper and safe concentration for downgrades. The mixture was dripped by pipette on each leaf would be 2-3 drops every week.

Risk of death

According to Ir Jos Sutiyoso, fertilizer experts in Jakarta, paklobutrazol retardants are compounds (inhibitors, red) that serves 'memingsankan' growing point so that the cells stop dividing. Plant growth regulators that inhibit the biosynthesis of gibberellins, hormones that stimulate the growth and development of plant cells. The result leaves grow up to be stunted. In agriculture paklobutrazol commonly used for the uniform appearance of mango and durian flowers.

Mixed carbide also has a role. According to Ir Ari Purwanto Wijayani MP, professor of Plant Physiology Faculty of Agriculture, University of National Development Veteran Yogyakarta, calcium derived from carbide (CaC2) can inhibit plant growth. Calcium causes the cell walls become stiff, so hard to divide. After all, according to Josh paklobutrazol and carbide can be used separately. Because they are the same role, then a raw material was enough.

Willy experience treatment with a solution pengerdil it only makes the leaves grow abnormally while. That is, if treatment is stopped the growth of plants back to normal. So that plants are not stressed, after treatment she added vitamins B1 and fertilizer leaves with a dose 1.5 times higher than recommended doses in the packaging. The goal is that the mini-sized leaves become thicker and look more fat.

Ari reminds avoid giving nitrogen derived from ammonium (NH 4). 'Ammonium weaken the plant cell,' he said. As a result, plants become vulnerable to illness. Moreover, plants 'hurt' over and over. We recommend using nitrogen derived from nitrate (NO3). Ari also recommends the use paklobutrazol and carbide with the mix itself should be careful. Plants can die if the dose is too high. It refers to the ease of mango and durian which languish and die after being given paklobutrazol excess.

Fuel rhizome

To create a mini Sansevieria Willy also uses techniques rhizome fuels. Sansevieria pull the trick of the pot, then clean the rhizomes from the media. Sprinkle a teaspoon of mashed Urea rhizome evenly all over, then sprinkle a teaspoon of chlorine (CaOCl2) as a 'burner'. After that, let stand for 15 minutes, then put it again on poor sand media which have been sifted until smooth.

For treatment, a week after watering crops planted in the media. Avoid watering wet because it will dissolve the urea and chlorine attached to the surface of the rhizome. Just give a little water on the surface of the media near the lip of the pot so far from the rhizome. Watering is only done when the media looks dry. Three months later came the mini-leaved seedlings.

According to Jos such technique is essentially the same: make the plants become sick. Urea containing ammonium role weakens the plant cell. In the weak condition, then hit the provision of chlorine from oxidative aka 'burn'. As a result, the growing point is damaged rhizomes.

Damage to the point of making a new generation who grew up experiencing the mutation. 'The size of the cells become smaller, "said Ari. Such mutations are at kimera alias several groups of cells, rather than at the gene level. That is, only generate temporary abnormal plants. When planted in fertile medium, growth returned to normal.

In order for a permanent mutation, should be planted on nutrient-poor media. After all, Sansevieria plants classified as recalcitrant. That way, Sansevieria fixed mini-sized, but the price maxi. (Imam Wiguna)
