1 2020_Morphology_SSTI.txt

Results of common garden experiments in 2020 for individuals from various habitats at three localities. Morphological traits and salt spray tolerance (SSTI) were examined. Collection sites: A (Maruyama island in the Seto Inland Sea), B (Cape Muroto facing the Pacific Ocean), and C (Cape Naruto facing the Pacific Ocean). Habitats: Site A (SS, sandy shore; HL, hinterland), Site B (PS, pebble shore; RC, rock crack), C (FG, flower garden; RC, rock cliff).

Measured traits:

• DayTH, days to heading;
• PL, plant length (cm);
• PaL, panicle length (cm);
• PaW, panicle width (cm);
• CL, culm length (cm);
• FLL, flag leaf length (cm);
• SLL, second leaf length (cm);
• 1INTL, first internode length (cm);
• 1SL, first sheath length (cm);
• 2INTL, second internode length (cm);
• 2SL, second sheath length (cm);
• NoT, number of tillers;
• SSTI, salt spray tolerance index (1 to 6).

2 2021_Morphology_SSTI.txt

Results of common garden experiments in 2021 for individuals from various habitats at two localities. Measurements and abbreviations are as in file 1.

3 2020_Lateflowering_Morphology_SSTI.csv

Results of common garden experiments in 2020 for late flowering individuals from pebble shore and rock cracks at Site B (Cape Muroto). Measurements and abbreviations are as in file 1.

4 2021_Lateflowering_Morphology_SSTI.csv

Results of common garden experiments in 2020 for late flowering individuals from pebble shore and rock cracks at Site B (Cape Muroto). Measurements and abbreviations are as in file 1.

5 20202021_Transplant.txt

Results of transplant experiments of four coastal and inland variants of S. viridis at the cliff and inland in 2020 and 2021. Survival rate (SurvRate (%)), number of panicles per plant (NOPan/plant), and total dry weight (TDW/plant (g)) were recorded. Five variants differing in plant size and salt spray tolerance were as follows: ST, short and tolerant (common variant); TM, tall and mid-tolerant (Inland Sea); TT, tall and tolerant; PT, prostrate and tolerant; L, extremely late flowering; I, inland and susceptible variants.

6 20202021_siteB_Monitoring.txt

Monitoring by mapping individuals in pebble shore and rock cracks at Cape Muroto in 2020 and 2021. Number of plants/quadrate (NOPlant), number of flowering plants/quadrate (NOFlower), survival rate (SurvRate (%)) and flowering rate (FlowerRate (%)) were recorded at every observation time. Data from Site B for April and May 2020 and April 2021 were lacking due to the travel restrictions enforced during the COVID-19 pandemic.

7 20142015_siteA_Monitoring.txt

Monitoring by mapping individuals on the sandy shore and hinterland at Maruyama Island in 2014 and 2015. Records were as file 6. Abbreviations of variants are as in file 5.

8 2015_TyphoonEffect.txt

Effects of typhoon GONI hit on 26 August 2015 on the survival of individuals on the sandy shore and hinterland at Maruyama Island. Numbers of living plants/quadrate (NOLiving) were shown before and after a typhoon touched down to calculate the number of plants destroyed by the typhoon (NODead).

9 SSTI_F2Segregation.txt

Segregations of four F2 populations in salt spray tolerance (SSTI). Abbreviations of variants are as in file 5.

10 Plantlength_F2Segregation.txt

Segregations of four F2 populations in plant length. Abbreviations of variants are as in file 5.

11 Daystoheading_F2Segregation.txt

Segregations of four F2 populations in days to heading. Abbreviations of variants are as in file 5.

12 SSTI_F2F3Correlation.txt

Correlations of two F2 and F3 populations in salt spray tolerance (SSTI). Abbreviations of variants are as in file 5.

13 Daystoheading_Lateflowering_Progeny.txt

Days to the heading of the progeny of individuals flowering at an intermediate time between normal flowering plants and extremely late flowering plants (L variant). The late and normal flowering plants (L and PT variants) were used as standards.
