All the seed containers were watered (30 ml in the molded containers, 20 ml in the tubular vats and 15 ml in the conical pots) before being planted with 30 naked caryopses of L.
The time (days' number) between the sowing and the appearance of the first shoots, the number of days between sowing and the maximum germination, and the number of caryopses that germinated were recorded.
GR = NFC/USQ x 100%; with NFC = number of fertile caryopses; USQ = number of plants produced per total caryopses used.
A one-way ANOVA was used to compare the percentage of germination of the naked caryopses of L.
The germination rate of the caryopses generally increased significantly in response to the substrate refinement (P < 0.
The germination energy of the caryopses ranged from 5 to 10 days, depending on the seed container and substrate types.
In general, morningglory seeds had higher germinability and mean germination rate than barnyardgrass caryopses, but this result may be explained by the scarification to which the morningglory seeds were subjected (Figure 3).
In PEG-6000 solutions, 80% of barnyardgrass caryopses germinated at osmotic potentials of 0 and -0.
in press(b)] and Schismus arabicus (Gutterman, submitted), post-matured caryopses (seeds) require about 70 days of dry storage at high temperatures of 35 [degrees] or 40 [degrees] C in order to be ready for germination.
arabicus caryopses for 70 days from maturation at -18 [degrees] C.
Examples are the caryopses of Schismus arabicus, as already mentioned, which may germinate in winter after less than 10 mm of rain but in high summer temperatures, when relative humidity is low, may germinate only after receiving more than 90 mm of artificial irrigation.
Freshly harvested caryopses or caryopses stored under low temperatures did not germinate.
