According to equation (8) and (9), so long as we know the tillers number at the first three leaf age after transplanting (normally leaf age 4, 5, 6 for machine- transplanting rice) and TRTT at each leaf age, the tillers number at any leaf age before jointing stage could be estimated.
Therefore, the TRTT is mainly affected by genotype, water and nutrient supply, and LAI.
In all treatments, TRTT decreased with the increase of LAI (Fig.
At a given LAI, slight variation in TRTT was observed among different planting densities especially when LAI was lower than 0.8 or greater than 2.2 (Fig.
Thus, we can infer that planting density had little effect on the relationship between TRTT and LAI; similar findings were reported by Zhong et al.
2), TRTT remained nearly constant (~1) at a lower RSPAD (RSPADless than-3), and decreased with the increase of RSPAD when RSPADgreater than -3.
To our knowledge, this is the first report on the concept of TRTT and on the quantitative relationship between TRTT and RSPAD in rice crop.
