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.

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).

Enzymatic mechanisms in the respiration of spinach leaves.

TL;DR: The respiration of spinach leaves was investigated by in vivo studies of gas exchange of excised leaf sections and by an examination of undivided enzymes and enzyme systems in vitro.

Phosphorus transformations during the development of the oat embryo

TL;DR: Studies were undertaken in an attempt to fractionate and identify the phosphorus compounds of the oat embryo, to ascertain whether the character of such compounds changes as the metabolism of the embryo changes, and finally to determinie whether "energy-rich" phosphorus compound of the adenosine triphosphate variety are present, and how these vary during development.

Changes in Phosphorus Fractions and Phytase Activity of Rice Seeds during Germination

TL;DR: The present experiment provides information on the phosphorus compounds in rice seeds and elucidates the changes they undergo during germination and suggests that there exist two phytases, one acidic and the other alkaline.
