POINSETTIA-CHRISTMAS TREE: Merah Merona Usai Dipingit

Agar pucuk daunnya – sering dikira bunga, bisa berkelir merah menyala, poinsettia perlu perlakuan khusus. Christmas tree itu mesti dipingit dan disungkup.

Poinsettia tidak dipingit, kelir pucuk daunnya bakal tetap hijau. Kenapa bisa begitu? Warna merah pertanda kastuba sedang mengalami masa generatif. Padahal flora menawan asal Meksiko dan Amerika Tengah ini termasuk short day plant. Nah, tanaman macam ini butuh masa terang harian lebih pendek dari masa gelap untuk memasuki masa generatif.

Sementara di Indonesia, masa gelap dan masa terang fifty-fifty. Supaya masa gelap menjadi panjang. masa terang harus dikurangi. Poinsettia lantas disungkup dengan plastik warna hitam. Tapi tidak disungkup sepanjang hari, karena tanaman tetap butuh sinar matahari agar bisa berfotosintesis, terang Budhi Hardjoko Oirektur Kebun Ciputri di Cipanas, Bogor.

Pingit empat jam

Cara penyungkupan sebenarnya sangat sederhana. Tinggal tutup mulai jam 4 sore dan dibuka lagi jam 8 pagi, ujar Budhi. Penyungkupan akan memotong ‘siang hari’ menjadi hanya delapan jam sehari. Masa terang itu cukup pendek untuk merangsang poinsettia menghasilkan bakal bunga sekaligus hormon pembentuk warna.

Kelir pucuk yang muncul tak hanya merah. Ada juga yang berpucuk pink, lemon/kuning dan putih, tergantung varietasnya. Kebun Ciputri juga punya varietas berwarna marble star yang berpucuk pink, namun tepi daunnya putih kekuningan. Sebenarnya kami juga punya varian variegata berpucuk merah. Tetapi kalau , pucuknya me me
rah, totol-tolol putih pad a semua daun semakin tidak kentara, papar alumnus Biologi Universitas Indonesia.

Semakin lama dalam pingitan, daun yang berubah warna akan semakin banyak. Kemunculan kelir dimulai dari pucuk daun paling atas dan berangsur turun ke daun di bagian bawahnya. D Ciputri, penyungkupan berkisar antara satu setengah sampai dua bulan. Tergantung ukuran tanamannya, lanjut Budhi. Selain warna sip, penampilan juga ditunjang oleh bentuk tajuk. Agar tajuknya kompak, jarak antar ketiak daun harus cukup pendek. Kalau terlalu panjang akan membuat tajuk terlihat jangkung namun
tidak proporsional. Bisa diatur dengan pemberian growth regulator, kami pakai merek cultar, ujarnya.

Butuh matahari

Menurut Budhi, warna pucuk daun bisa balik lagi ke warna aslinya Kalau rentang masa terang kembali ke normal. Namun proses membungIon itu tak terjadi serta merta. Kelir merah di pucuk daun bisa tahan antara dua sampai tiga bulan, ungkapnya.

Yang justru sering dikeluhkan adalah daun cepat layu dan rontok. Banyak yang menduga akibat perpindahan tempat dari dataran tinggi ke dataran rendah. Namun hal itu ditamplk oleh Budhi Hardjoko Menurutnya, mexican flame leaf tetap bisa tampil bagus di dataran rendah Memang di dataran tinggi kelir pucuknya akan lebih tegas dan menyala.

Rontok yang terjadi hanya akibat salah rawat. Kalau ditaruh dalam ruangan terus bagaimana enggak rontok. Saalnya tak mendapat cahaya matahari, makanya enggak bisa berfotasintesis, ujarnya.

Kastuba memang bukan tipe tanaman yang tahan berada dalam ruangan pada periode lama. Dua minggu dalam ruangan terus-menerus akan membuatnya layu dan rantok
Boleh menaruhnya sebagai penghias ruang tapi harus rajin mengeluarkannya. Sebaiknya dua hari sekali ditaruh teras untuk mandi matahari Cahaya matahari juga akan membuat warnanya tetap cerah. Tapi jangan ekstrim menaruhnya di terik matahari Sebaiknya taruh di teras yang terkena sinar matahari tidak langsung, sarannya.

Selain tak mendapat pasokan matahari, kerontokan juga bisa terjadi karena terlalu ban yak air. Penyiraman terlalu sering akan membuat media lembap dan rentan busuk akar. Kalau akarnya sudah sakit, bagian tubuh lain pasti ikut merana.

Siram kalau media sudah terlihat kering. Gunakan metode siram ‘cuci kaki’, siram media dan jangan kena tanamannya. Tanaman basah lebih mudah terserang hama dan penyakit, ungkap Budi.

Nah, jangan salah lagi!

POINSETTIA CHRISTMAS-TREE: After rosy seclusion

In order to shoot the leaves - often mistaken for flowers, can berkelir red, poinsettias need special treatment. Christmas tree it must be secluded and disungkup.

Poinsettias are not secluded, leaf color will remain green shoots. Why is that? The red color sign kastuba been going through a generative. Though charming flora of Mexico and Central American origin include short day plant. Well, these kinds of plants need a daily light period shorter than the period of darkness to enter the generative period.

While in Indonesia, the dark and the light of a fifty-fifty. In order to be a long dark period. the light should be reduced. Poinsettia then disungkup with black plastic. But not disungkup all day, because the plants still need to be able to photosynthesize sunlight, bright Budhi Hardjoko Oirektur Ciputri Gardens in Cipanas, Bogor.

Pingit four hours

Penyungkupan actually very simple way. Stay closed from 4 pm and opened again at 8 am, said Budhi. Penyungkupan will cut 'daytime' to only eight hours a day. Light period was short enough to stimulate poinsettia flowers will produce hormones as well as color formers.

Screen shoots that appear not only in red. There is also a pink bud, lemon / yellow and white, depending on variety. Ciputri garden also has a colored marble varieties that sprout pink star, but the leaves are yellowish white edge. Actually we also have a variant of the red bud variegata. But if, bud to me
red, white dots-pad is a fool all the leaves more subtle, said an alumnus of Biology, University of Indonesia.

The longer in seclusion, the leaves are changing colors will be more and more. The emergence of the leaf color starts at the top and gradually down to the leaves at the bottom. D Ciputri, penyungkupan ranged from one half to two months. Depending on the size of the plant, said Budhi. In addition to sip color, appearance is also supported by the shape of the canopy. In order to editorial compact, the distance between the armpit leaves should be short enough. If it is too long will make the canopy look tall but
disproportionate. Can be regulated by administering growth regulators, we use brand cultar, he said.

Need sun

According to Budhi, leaf color can be back to its original color if the range of the light back to normal. But it did not happen membungIon process immediately. Red leaf color can last between two to three months, he said.

Frequent complaint is that it leaves quickly wither and fall off. Many suspect due to migration from the highlands to the lowlands. But it ditamplk by Budhi Hardjoko opinion, mexican flame leaf can still look good in the lowland plateau Indeed in the bud will be more assertive color and light.

Loss that occurs as a result only one patient. If placed in the room how baseball continues to fall. Saalnya not get sunlight, so baseball can berfotasintesis, he said.

Kastuba is not the type of resistant plants are indoors on a long period. Two weeks in the room will constantly make it wither and rantok
May put them to decorate the space but must be diligent in removing it. Every other day should be put terrace for sunbathing sunlight will also make the colors remain bright. But do not put them in extreme sun terrace which should put it in indirect sunlight, he suggested.

In addition to not get a supply of sun, hair loss can also occur because the water was too tire yak. Watering too often will make the media moist and vulnerable to root rot. If roots are sick, other body parts would come languish.

Flush when the media was seen to dry. Use the flush method 'washing feet', flush the media and do not hit the plants. Wet plants more susceptible to pests and diseases, said Budi.

Well, make no mistake again!
