Title

Effects of Different Cultivation Methods and Nitrogen Fertilizer Application on Rice Yield

Liu Liang-ju Hubei nongye kexue 2015

Other claims from this paper (4)

Intervention effect The effect of nitrogen application amount on yield was reduced after an initial rise.
Intervention effect Too low or too high planting density was not conducive to improving the yield of Wanxian 98.
Intervention effect A planting density of 16.5 cm×20.0 cm gave the highest yield, 8506.5 kg/hm2.
Intervention effect Planting four, six or eight basic seedlings per hole gave higher yields, with actual yields of 8 496.0, 8 569.5 and 8 470.5 kg/hm2 respectively.

Salt stress induces SFT expression to promote early flowering and inhibits floral organ development by disturbing cell cycle in tomato

Fengze Sun; Yahui Wang; Genzhong Liu; et al. Vegetable Research 2024. doi:10.48130/vegres-0024-0017

Other claims from this paper (9)

Intervention effect Salt stress significantly reduced tomato plant biomass compared with the control.
Intervention effect Tomato plants treated with 50-150 mM NaCl showed an early flowering phenotype relative to the control.
Intervention effect Tomato plants treated with 50-150 mM NaCl produced smaller flowers relative to the control.
Intervention effect The SFT gene was upregulated under salt stress in tomato, as shown by RT-qPCR.
Intervention effect Salt treatment decreased tomato seedling biomass, particularly in the floral organ.
Intervention effect Tomato plants treated with 150 mM NaCl produced much smaller fruits than the control.
Intervention effect Nuclear DNA ploidy analysis showed significant impacts of salt stress on intranuclear replication in tomato sepals and petals.
Mechanism The authors indicate that salt stress disrupts the cell cycle in floral organs, primarily by influencing transcription of CycA2;1 and CycB1;2.
Mechanism The authors conclude that salt stress promotes early flowering in tomato by inducing SFT expression.
