Regulation of growth in rice seedlings

Journal of Plant Growth Regulation, 1983
Etiolated rice seedlings (Oryza sativa L.) exhibited marked morphological differences when grown in sealed containers or in containers through which air was passed continuously. Enhancement of coleoptile and mesocotyl growth and inhibition of leaf and root growth in the sealed containers (“enclosure syndrome”) were accompanied by accumulation of CO2 ...

Role of nano-biochar in attenuating the allelopathic effect from Imperata cylindrica on rice seedlings

, 2020
It is reported that Imperata cylindrica, a successful invasive plant in North America, has covered many parts of the United States, especially the southeastern region which is the main rice growing region. The invasion of I.

Agmatine deiminase in rice seedlings

Phytochemistry, 1985
Abstract Agmatine deiminase activity in rice embryos increased gradually upto 24 hr during germination and then decreased. Gibberellic acid and kinetin inhibited the activity when added to the germination medium. The enzyme was purified 717 fold with specific activity 788.5 nkat/mg protein and yield 8.8%.

New adventitious root formation and primary root biomass accumulation are regulated by nitric oxide and reactive oxygen species in rice seedlings under arsenate stress.

Journal of Hazardous Materials, 2019
Nitric oxide (NO) and reactive oxygen species (ROS) are important signaling molecules regulating development of plants. However under metal stress, in developmental processes of plants their implications are not largely known.

Phasic Development of Rice Seedlings

Agronomy Journal, 1997
AbstractA better understanding of growth and developmental processes of rice (Oryza sativa L.) seedlings is necessary for crop management and modeling perspectives. This experiment was conducted to identify preautotrophic phases of rice seedlings, quantify seed dry matter mobilization and utilization, characterize dry matter partitioning during early ...

Biochar alleviated the salt stress of induced saline paddy soil and improved the biochemical characteristics of rice seedlings differing in salt tolerance

, 2019
Biochar is used mainly to alleviate salt stress in arid and semiarid soils, or to regulate acidification stress in paddy soils. However, the effects of biochar on paddy soil environments under salt stress and the biochemical characteristics of rice ...

Enantioselective Separation and Phytotoxicity on Rice Seedlings of Paclobutrazol

Journal of Agricultural and Food Chemistry, 2011
The environmental significance of enantioselectivity in chiral insecticides and herbicides has been widely studied. However, little information is currently available on the enantioselective behavior of chiral plant growth regulators. In this study, paclobutrazol enantiomers were resolved and prepared by chiral high-performance liquid chromatography ...

Rice BIG gene is required for seedling viability

Journal of Plant Physiology, 2019
Arabidopsis BIG (AtBIG) gene encodes an enormous protein that is required for auxin transport. Loss of AtBIG function not only profoundly changes plant architecture but also alters plant adaptability to environmental stimuli. A putative homolog of AtBIG exists in the rice genome, but no function has been ascribed to it.

Metabolism of Glycine in Roots of Wheat and Rice Seedlings

Journal of Plant Physiology, 1984
Wheat and rice roots have been shown to decarboxylate both the carbon atoms of glycine. Cold formate and serine significantly depressed (14)CO(2) evolution from (2-(14)CO) glycine. It is therefore likely that C(1)-tetrahydrofolate pool is involved in 2-C-glycine metabolism.
