Life cycle of a plant (spermatophyte) sets off by germination of seeds that virtually transfer successfully genetic information from parents to off-springs across adverse environmental conditions. Considering the pivotal roles played by both hormones and ROS (especially H2O2and˙OH radical) during seed...
Seed priming at subgermination water potential has been shown to enhance the germination response of a wide number of plant species. Optimal priming conditions for germination enhancement are usually found to be at the least negative water potential that prevents radicle emergence. Equilibration of see...
This study reports fundamental requirements for seed germination and seedling growth of D. dregeana. Germination responses of seeds were tested at different temperature regimes, light conditions and smoke treatments. The highest percentage germination (>= 95%,) and mean germination time (MGT) of 10...
(3) the various dispersing agents must be given time to act. Accordingly, the wide variation in seed and diaspore longevity can be appreciated only by linking it with the various dispersal mechanisms employed as well as with the climate and its seasonal changes. Thus, the downy seeds of...
the ability of a seed to yield normal sprouts after a set period of time in defined sprouting conditions. In the USSR seed germination is defined by state seed inspection in controlled seed analysis following a method prescribed by the All-Union State Standard (GOST 12038-66). The number of...
How To Set Up Your Seed Experiment STEP 1: Fill the jar with paper towels. Kids can fold them and push them down into the jar. This is also great work for little hands. STEP 2: Gently water your seed jar to wet the paper towels. DO NOT FLOOD IT!
the tested hypothesis was that seed germination increases with increasing temperatures and water potentials in a. lampa, l. divaricata, l. erianthus, s. neaei and p. ligularis, and that time to reach 50% of total germination is greater at lower than higher water potentials. peg 2000 was ...
based on the hydrotime model, the base water potential showed lower values of −7.74 and −10.90 MPa at the optimal temperatures of 25.0°C and 30.0°C, respectively. Also, the species was found to have excellent tolerance to drought (water stress) compared to salt stress, which has imp...
The results of the germination experiments revealed that the seeds require a low-temperature environment for germination; those exposed to low-temperature conditions for a time similar to the length of winter (4 months of low-temperature conditions) germinated gradually, while those exposed for longer...
