For the IG parents and IG/IG progeny, rhizome presence and expression were positively associated with survival and vigor of the survivors.
Significant negative correlations were observed between the SES and all other parameters related to salt tolerance such as SL, RL, FWsht, and DWsht (Table 1), which is expected because a lower SES score indicates higher tolerance, which is based on seedling survival and vigor.
In these conditions, having little vegetative tissue at the end of flowering would be expected to reduce survival and future vigor, because there is little time for vegetative recovery before the return of cold temperatures (Fig. 6b).
Parents and progeny were planted in an upland field at IRRI using a randomized complete block design and evaluated for rhizome expression, survival after 1 year, vigor of the survivors, and yield.
Thus, megafaunal fruit species could take advantage of interacting with frugivores capable of dispersing seed loads much larger than those dispersed by extant frugivores and including much larger individual seeds, ultimately entailing increased advantages in terms of seedling vigor and survival prospects.
However, it is impossible with the RH approach in plants to go beyond a certain level of radiation as the increase in dosage leads to decrease in seed germination, plant survival, fertility and poor vigor [ 14, 18, 24].
The traits included relative root length, stem length, fresh weight per plant, survival rate, electrical conductivity, and vigor index.
Germination vigor and seedling survival rate are the two main criteria used for the evaluation of cold tolerance in rice at the germination stage.
The hybrids exhibited hybrid vigor for growth and survival, as well as a higher temperature tolerance, showing great potential for application in the abalone aquaculture industry in southern China.
Considering plant survival in the wild, optimal seedling vigor would be a strong evolutionary force to select for genotypes of plants with starch granules optimized for molecular structure that would lead to efficient storage and utilization.
