Effects of toxic concentrations of natrium fluoride on growth and enzyme activities of rice ( Oryza sativa L.) and jute ( Corchorus olitorius L.) seedlings
TLDR
Germination was increasingly inhibited at concentrations above 5 and 20 mM and stopped altogether at 80 and 50 mM NaF in rice and jute respectively, whereas the inhibition of seedling growth began at much lower concentrations.Abstract:
Germination was increasingly inhibited at concentrations above 5 and 20 mM and stopped altogether at 80 and 50 mM NaF in rice and jute respectively, whereas the inhibition of seedling growth began at much lower concentrations. Of the enzymes, RNase activity was increased by fluoride, while α-amylase, protease, phytase and ATPase activities exhibited distinct inhibition from the control.read more

Studies on the impact of fluoride toxicity on germination and seedling growth of gram seed (Cicer arietinum L. cv. Anuradha)
TL;DR: 4.0 mM F concentration was found to be most sensitive for gram seeds and germination occurred but plants were totally dried after completion of treatment period.

Seed Priming Improves Agronomic Trait Performance under Flooding and Non-flooding Conditions in Rice with QTL SUB1
TL;DR: Seed priming had positive effects on yield and yield attributing parameters both under non-flooding and early flooding conditions and outperformed Swarna-Sub1 when the plants were cultivated under flooding.

Role of starch hydrolytic enzymes and phosphatases in relation to under water seedling establishment in rice
TL;DR: The activities of starch hydrolyzing enzymes and phosphatases were studied in seedlings of three Indica rice (Oryza sativa L.) cultivars, namely Panikekoa & T 1471 that showed good capacity for seedling establishment under submergence (tolerant) and IR 42 which had poor under water seedlingestablishment capacity (susceptible).

Possible Explanation of Fluoride-Induced Respiration in Chlorella pyrenoidosa.
Irving B. Mcnulty,James L. Lords +1 more
TL;DR: Measurements of gas exchange at several pH values indicate that the stimulation of Chlorella pyrenoidosa is probably related to the undissociated hydrogen fluoride concentration in the suspending media.

Effects of Fluoride on Mitochondrial Activity in Higher Plants
J. E. Miller,G. W. Miller +1 more
TL;DR: The effects of fluoride on respiration of plant tissue and mitochondria were investigated and fluoride was found to increase the amount of osmotically induced swelling and cause a more rapid leakage of protein with mitochondria isolated from etiolated corn shoots.

TL;DR: In the presence of phosphate, fluoride caused marked inhibition of succinic 2,6-dichlorophenolindophenol reductase, and it is believed that this inhibition results from an enzyme-fluorophosphate complex which has a lower dissociation constant than that of the enzyme-substrate complex.
