Linear Pattern

Selenium is an essential and also toxic trace element for organisms including plants. We studied the role of selenium (Na2SeO4) on growth and carbohydrate metabolism and its interaction with sulphate (Na2SO4) in rice (Oryza sativa L. cv. Satabdi) seedlings. Low concentration of selenium (2µM) showed stimulatory effect on growth as opposed to its higher concentration (50µM). Selenium was found to accumulate in a dose dependent linear pattern in the plant tissues. Exposure to selenate increased both reducing and non reducing sugar contents in the rice seedlings accompanied with an increase in the activities of sugar metabolizing enzymes like Sucrose Synthase (EC 2.4.1.13) and Sucrose Phosphate Synthase (EC 2.4.1.14). An increase in Starch Phosphorylase (EC 2.4.1.1) activity corresponded with the reduction in starch contents in the rice seedlings. Since Selenium is chemically analogous to sulphate, simultaneous application of sodium sulphate (10mM) and selenate (Na2SeO4) was found to ameliorate partially or totally all the tested parameters under selenate treatment alone resulting in alteration of growth and development of the test seedlings.

Keragaan morfologi dan kandungan antosianin padi beras merah (Oryza sativa L.) pada Kecamatan Munte dan Kecamatan Payung di Kabupaten Karo. Penelitian ini bertujuan untuk mendapatkan informasi morfologi dan kandungan antosianin padi beras merah (Oryza sativa L.). Penelitian ini dimulai dari Juni 2017dan selesai pada Januari 2018 di kecamatan Munte dan Kecamatan Payung Kabupaten Karo.Metode survei deskriptif menggunakan panduan International Rice Research Institute (IRRI). Teknik penentuan lokasi secara sengaja dan pengamblan sampel secara kebetulan.Uji kandungan antosianin menggunakan metode analitik dengan menghomogenkan sampel. Hasil eksplorasi didapatkan 72 genotipe yang dibagi menjadi tiga lokasi lahan. Berdasaran uji kandungan antosianin didapatkan lahan A memiliki kandungan tertinggi yaitu 0,5 mg/100 g dan terendah yaitu lahan B 0,08 mg/100 g.

Experiments were carried out to assess some insecticide modules against major insect pests of rice. Each module consists of a basal application of carbofuran 3G @ 1 kg a.i ha-1 at 20 DAT and Rynaxypyr 20 SC @ 30 g a.i ha-1 at 45 DAT except untreated control. All modules differ with each other only in third treatment which was applied in 65 DAT. The third treatment includes: Imidacloprid 17.8 SL @ 27 g a.i ha-1, Pymetrozine 50 WG @ 150 g a.i ha-1, Triflumezopyrim 106 SC @ 27 g a.i ha-1, Buprofezin 25 SC @ 250 g a.i ha-1; Glamore (Imidacloprid 40+Ethiprole 40% w/w) 80 WG @ 100 g a.i. ha-1, Thiacloprid 24 SC @ 60 g a.i ha-1, Azadirachtin 0.03 EC @ 8 g a.i ha-1, Dinotefuran 20 SG@ 40 g a.i ha-1 and untreated control. All the treated plots recorded significantly lower percent of dead heart, white ear- head caused by stem borer and silver shoot caused by gall midge. Module with Pymetrozine 50 WG @ 150 g a.i ha-1 treated plot recorded significantly higher per cent reduction of plant hoppers (>80% over untreated control) and produced higher grain yield (50.75 qha-1) than the other modules. Among the different treated modules the maximum number of spiders was found in Azadirachtin 0.03 EC @ 8 g a.i ha-1 treated module plot followed by other treatments.
