Welcome to the crop physiology practical for the Seed Viability and Seed Moisture Content practical sessions of the Crop Physiology (AGR3301) course! Accurate assessment of seed quality is vital for predicting crop performance and ensuring optimal storage.
We demonstrate and compare three distinct approaches for assessing the seed viability:
1. Tetrazolium (TZ) Test (Chemical/Quick Test): Learn how to use this rapid chemical method to visually confirm active respiration in the embryo. Viable embryos turn red, indicating potential for germination.
2. Paper Towel Method (Conventional Test): We set up the standard germination test using moist paper towels to determine the percentage of normal seedlings that develop under ideal conditions.
Seed Moisture Content (MC):
1. Slow Sun Drying (Sun dry for 7 days)
2. Rapid Oven Drying (130 °C for 1 hour)

Resubmission: ❌ Issues Still Not Fixed
Graph x-axis label "Drying Metod and Seed Type" — misspelled, should be "Method"
Oven still lacks manufacturer/model number (line 112)
"Weighted" should be "weighed" (rapid drying step 5 photo table, and slow drying step 4 photo table)
Comments for Group Veronica:13/20 (Moisture)
The table of contents does not carry a heading at all, and the heading for the Results section in the table of contents is singular rather than plural. (line 19) The table of contents page begins at line 19 with the table itself, but there is no "TABLE OF CONTENTS" heading above it. Additionally, the table lists "RESULT" rather than "RESULTS," and this singular form is carried through to the actual section heading at (line 176). You need to add a "TABLE OF CONTENTS" heading above the table and correct both instances to read "RESULTS."
The table of contents omits section numbers from every entry. (line 19) Entries are listed as "INTRODUCTION," "OBJECTIVES," "MATERIALS AND METHODS," and so on,…

Resubmission: ❌ Issues Still Not Fixed
(1) The References list still uses a numbered format (1., 2., 3. etc.) which is not APA 7th edition style (lines 182–207). You need to remove the numbers and present entries as an alphabetical hanging-indent list.
(2) The Abstract states the oven temperature as "130°C" without a space before the unit (line 22). It should read "130 °C." The same applies in the Methods photo-caption step 3 (between lines 81 and 82), which reads "130°C." Check the entire document and add the required space consistently.
(3) The Methods step 2 photo-caption for both fast and slow drying reads "The step is repeated for other seeds" in the present tense (between…

(1) "et al," throughout Introduction and Discussion still missing the period — should be "et al.," (lines 53, 60, 63, 71, 196, 201, 206, 216).
(2) "favorable" in the Discussion should be "favourable" (line 209).
(3) Step 3 of the TZ Methods still says "cross section area" despite the cut now being described as longitudinal in step 2 — needs correcting to "the exposed inner surface" or similar (between lines 99 and 100).
(4) Step 5 Methods caption contains a present-tense error: "are taken out" should be "were taken out" (between lines 99 and 100).
(5) Temperature still written as "35 degrees" and "35°C" without the required space — should be "35 °C"…
