Germinability

Diastase or amylase is formed when malt is produced by the germination of barley grains. Malt is therefore a good source of the enzyme. Diastase is also secreted by the salivary glands (when it is known as ptyalin), and also by the pancreas. Its function is to hydrolysef starch to a mixture of maltose and dextrin ...

The estabhshment of safe thermal processes for preserving food in hermetically sealed containers depends on the slowest heating volume of the container. Heat-treated foods are called commercially sterile. Small numbers of viable, very heat-resistant thermophylic spores may be present even after heat treatment. Thermophylic spores do not germinate at normal storage temperatures. 

GibberelHc acid is also used successfliUy in rice culture to promote seed germination and the growth of semidwarf varieties. The treated seed can be planted deeper than normal. In addition, the sprouting seedlings are much taller than the untreated ones they compete weU against weeds. The material is sold under the trade name Release. 

Cell Division Inhibitors. The most common mode of action of soil-appHed herbicides is growth inhibition, primarily through dkect or indkect interference with cell division (163). Such growth inhibitory activity is the basis for most pre- or post-emergent herbicides intended to control germinating weed seeds. In germinating seeds, cell division occurs in the meristems of the root and the shoot. Meristematic cells go through a cycle... 

The various fumigants often exhibit considerable specificity toward insect pests, as shown in Table 8. The proper choice for any control operation is determined not only by the effectiveness of the gas but by cost safety to humans, animals, and plants flammabdity penetratabdity effect on seed germination and reactivity with furnishings. The fumigants may be used individually or in combination. Carbon tetrachloride has been incorporated with carbon disulfide, ethylene dichloride, or ethylene dibromide to decrease flammability, and carbon dioxide is used with ethylene oxide for the same purpose. 

Raw Materials. Two principal types of malting-grade badey are in use, ie, six-row and two-row. Six-row badey has six kernels around the stalk, whereas the two-row variety has two kernels. Six-tow kernels tend to be twisted, and the two-row grade is more symmetrical. Figure 1 is an illustration of a badey kernel and its key components. As badey is converted into malt, the acrospire for the embryo lengthens until it reaches the far end of the kernel, and roodets also grow as if the seed is germinating into a new plant. A discussion of the stmcture and composition of badey can be found in Reference 1. 

Investment, Costs, and Prices for Barley and Malt. Estimated malthouse investment (1993) and costs for a new malthouse with annual capacity of 120,000 t are shown in Table 2. This malthouse is equipped with twelve 1,700-bushel steep tanks, eight 10,000-bushel germination compartments, and two double-deck kilns. The kilns are equipped with standard heat recovery units and indirect heat.

Tyndalization, or fractional sterilization, is no longer considered acceptable for sterilization. Spores of vegetative organisms are the most difficult entities to destroy. In this procedure, rather than destroying the spores, spores are prompted to germinate and then destroyed by boiling water.
