Abstract

Cekaman kekeringan menyebabkan terjadinya perubahan terhadap pertumbuhan dan produksi tanaman diantaranya terjadinya penurunan laju asimilasi. Percobaan dilaksanakan di Rumah Plastik Lapangan Riset Padi Babakan, University Farm IPB, Bogor (± 240 m dpl) pada bulan September 2011 sampai February 2012. Rancangan penelitian menggunakan rancangan split plot 3 ulangan, dengan dua faktor perlakuan yaitu faktor utama (Cekaman kekeringan) sebagai petak utama yang terdiri dari penghentian pemberian air umur 3Minggu Setelah Transplanting (3MST) sampai panen; Penghentian pemberian air umur  6 MST sampai panen; penghentian pemberian air umur 9 MST sampai panen dan  kontrol.  Sedangkan faktor kedua adalah varietas yang ditempatkan sebagai anak petak yaitu IR 64, Ciherang, IPB 3S, Way Apo Buru, Jatiluhur, Menthik Wangi, Silugonggo dan Rokan. Hasil penelitian menunjukkan perlakuan cekaman kekeringan pada saat awal fase vegetatif sampai panen dan pada fase pra antesis sampai panen menyebabkan terjadinya penurunan laju asimilasi bersih berkisar 42.96%-78.95% dan laju tumbuh relatif berkisar 22.95%-69.62%. Varietas Jatiluhur dan Ciherang memiliki laju asimilasi bersih yang lebih tinggi pada perlakuan cekaman kekeringan yang diberikan pada awal fase vegetatif sampai panen

Abstract

Water stress is one of factors which causes low yield of lowland. This study aimed to identify and characterize morphology and physiology of drought tolerant rice varieties. Experiments which have conducted: (i) Investigation of rice varieties tolerance to drought stress at early vegetative stage in the laboratory (ii) morphology and physiology characters of rice varieties to drought stress in the paddy field and (iii) determining the character of root of  rice tolerant to drought stress. The experimental design used was split plot design with 3 (three) replications, with drought stress as the main plot and the variety as sub-plot. The result of screening test at the laboratory using PEG (Polyethylene Glycol) which could characterize which rice varieties could be considered as drought tolerant varieties. Results showed that periods of drought increasing the proline content at Ciherang (25.38 μmol) and IPB 3S varieties (22.08 μmol) at 13 WAT (Week After Transplanting). The variety that has the highest total sugar content in the flowering stage is Rokan (289.38 mg.g-1DW) followed by Menthik Wangi (230.53 mg.g1DW), while the lowest sugar content in harvest found in Jatiluhur (17.14 mg.g-1DW) followed by Way Apo Buru (46.99 mg.g-1DW). Jatiluhur, Way Apo Buru and IPB 3S varieties have drought tolerant based on the root characteristic. Ciherang, IPB 3S, Way Apo Buru and Jatiluhur varieties were drought tolerant and potential to be used in paddy field.
