Paclobutrazol And Cytokinin Regulation On Culm Growht Of Black Rice (Oryza sativa L. “Cempo Ireng”)

چکیده
Rice is a staple food for the majority of Asians; nevertheless, black rice has not been commonly consumed among them. The components yield will be determined by allocation photosynthate on and tall phenotype rice, which significant contributing factor to lodging. growth inhibitor paclobutrazol prevents manufacture gibberellin, results in rice. endogenous cytokinin content high at beginning grain filling then rapidly decreases after that. purpose study was compare effects culm height, internode length, diameter, lodging resistance, parenchyma cell arrangement, flag leaf structure. Throughout inquiry, Cempo Ireng cultivar seeds were employed. planted plastic containers that held 10 kg soil medium organic fertilizer, random block pattern used experiment's design. At weeks following sowing, sprayed as foliar application concentrations 0, 50, 100 ppm. By injecting kinetin diluted 0.8 percent agar gel rate 10-5 M lacuna twice, separated two days, anthesis. Eight replications six combinations made. DMRT different statistical analysis mean comparisons (P=0.05). Plant height length decreased (100 ppm), although diameter raised resistance induced. organization cells ppm packlobutrazol) changed, small lacked intercellular gaps.

Seventy genotypes of rice (Oryza sativa L.) were evaluated during Kharif 2012 to study the nature and extent of correlation among yield and yield attributing characters, days to 50 per cent flowering, days to maturity, number of effective tillers per plant, plant height, panicle length, number of grains per panicle, 1000-grain weight, grain yield per plant, kernel length, kernel breadth and L/B...
متن کاملThe relationship between nitrogen, auxin and cytokinin in the growth regulation of rice (Oryza sativa L.) tiller buds
Nitrogen (N), auxin and cytokinins (CTKs) play important roles in regulating the growth of rice tiller buds. However, little is known about the underlying mechanisms and the relationships between them in the regulation of tiller bud growth in rice. In the present study, N and auxin indole-3-acetic acid (IAA) were used to regulate tiller bud growth in Nanjing 44 rice, a japonica cultivar. The ti...
متن کاملInfluence of cooking on anthocyanins in black rice (Oryza sativa L. japonica var. SBR).
The composition and thermal stability of anthocyanins in black rice (Oryza sativa L. japonica var. SBR) produced in California were investigated. Six anthocyanin pigments were identified and quantified by high performance liquid chromatography using photo diode-array detection (HPLC-PDA) and electrospray ionization mass spectrometry [LC-(ESI)MS/MS]. The predominant anthocyanins are cyanidin-3-g...
متن کاملHierarchical additive effects on heterosis in rice (Oryza sativa L.)
Exploitation of heterosis in crops has contributed greatly to improvement in global food and energy production. In spite of the pervasive importance of heterosis, a complete understanding of its mechanisms has remained elusive. In this study, a small test-crossed rice population was constructed to investigate the formation mechanism of heterosis for 13 traits. The results of the relative mid-pa...
