Assessment Regression Relation between Wheat Seed Germination Characteristics Affected Sodium Hypochlorite (NaClO)
author
Abstract:
This research was conducted to assessment effect of different concentrations of sodium hypochlorite along several times on quantitative parameters of wheat seeds affected by Aspergillus flavus fungus via factorial experiment according randomized complete block design with four replications. The treatments consisted four concentrations of sodium hypochlorite or NaClO (C1= 2%, C2= 4%, C3= 6%, and C4= 8%) and four time use of NaClO (T1= 2, T2= 5, T3= 7, and T4=10 minutes). Result showed germination percentage and seedling dry weight, seed vigor index and seedling length had positive and significant relationship, but with percentage of abnormal seedling had negative and significant relation. Seedling growth rate with radicle length and plumule length had positive and significant relationship. Germination rate and mean germination time had negative and significant relationship. In general, it can be concluded that higher germination percentage led to increase seedling dry weight and seedling length also higher seed vigor index cause to improve germination percentage especially under environmental contaminants situation. Although lower germination percentage led to increase percentage of abnormal seedling. The higher radicle and plumule length depends to seedlings growth rate. Increasing seed quality and disinfection of the environment leads to an increase germination rate and a decrease mean germination time.

Determination Sodium Hypochlorite (NaClO) Application on Quantitative Parameters of Wheat (Triticum aestivum L.) Seed and Correlation Between Measured traits
To assessment effect of concentration and times of disinfection wheat seeds, infected by Aspergillus fungus a research was conducted based on Factorial experiment according randomized complete block design with four replications. The factors included four levels of sodium hypochlorite (2, 4, 6, and 8%) and four times of seed disinfection (2, 5, 7, and 10 minutes). Result of analysis of variance...

The aim of this study was to determine why food poisoning bacteria attached to cut cabbage are not efficiently disinfected by sodium hypochlorite (NaClO). Pretreatment of shredded cabbage with diethyl ether definitely decreased the survival numbers of Escherichia coli O157:H7 and Salmonella spp. after disinfection with 100 ppm of NaClO. The density of E. coli O157:H7 at the cut edge of a cabbag...

The effect of constant temperature on the germination rate and percentage of two cotton seed lots was determined using a thermogradient plate. A gradient of 10 oC to 40 oC was established across the plate so that temperatures changed 2 oC for each 5 cm increment in length, resulting in sixteen different temperature treatments. The optimal temperature zone for germination was 28 oC to 30 oC. As ...

Low concentration (0.5-0.8%) sodium hypochlorite is a viable solution for point-of-use drinking water chlorination programs in Nepal, and it can be produced on a small-scale at a low cost using relatively cheap, safe, and robust generators, appropriate for developing country conditions. This thesis describes the set-up and the testing of a sodium hypochlorite generator in Kathmandu, at the labo...
