Interaction between Kinetin and Light on Germination of Grand Rapids Lettuce Seeds.
At 260 Grand Rapids lettuce seeds require an exposure to white or red (6500A-6800A) light in order to germinate. This stimulating effect is reversed if this illumination is followed immediately by a brief exposure to far-red light (7000A-7500A). This phenomenon, discovered by Flint and McAllister (4), has been widely studied (3, 8). Many factors, such as lowering the temperature to 160 (1), can...
متن کاملNitric Oxide Scavenger Carboxy-PTIO Impaired Memory of Avoidance Conditioning in Goldfish
The long-term potentiation (LTP), an activity-induced increase in the efficacy of neurotransmission, has long been conceived to be a physiological correlate of learning and memory. Investigations of synaptic transmission suggest that the postsynaptic N-methyl-D-aspartate (NMDA) receptor is the upstream mediator of LTP, while nitric oxide (NO), a retrograde messenger from postsynaptic neurons to...
متن کاملEffects of a nitric oxide scavenger, carboxy-PTIO, on isoflurane MAC and cerebellar nitric oxide synthase activity in rats.
Recent studies have indicated that nitric oxide may play a role in inhalation anaesthesia. Inhibition of nitric oxide synthase reduces the minimum alveolar concentration (MAC) for inhalation anaesthetics and decreases cerebellar nitric oxide synthase (NOS) activity in rats. In this study, we have explored further the role of nitric oxide in isoflurane anaesthesia by examining the effects of a n...
متن کاملReactions of PTIO and Carboxy - PTIO with
Nitronyl nitroxides, such as derivatives of 2-phenyl4,4,5,5,-tetramethylimidazoline-1-oxyl 3-oxide (PTIOs), react with NO to form the corresponding imino nitroxides (PTIs) and NO2. PTIOs are considered as monitors of NO, stoichiometric sources of NO2, biochemical and physiological effectors, specific tools for the elimination of NO, and potential therapeutic agents. However, a better understand...
متن کاملApplication of Computer Vision for Lettuce Seeds Germination Detection
This paper presents a unique application of computer vision methods designed to detect germination of lettuce seeds under controlled environment. Two steps involved in this application are image acquisition and image analysis which uses image skeletonization and other image processing algorithms. Seed images are converted to binary images followed by extraction of seed skeletons, which are used...
