“…Similar results were found in an experiment conducted by Yao et al [12]. In an experiment conducted by Hassan et al, it was evident that the combinations of equal amount of perlite and vermiculite as a potting media led to better results in plant development than either used the substrates alone [13].…”

The present study was carried out to investigate the impact of different substrates on the primary and secondary hardening of tissue culture raised banana plantlets. Among eight different treatment combinations of potting mixtures, treatment PHT7 which contained cocopeat with the combination of perlite and vermiculite (2:1:1) emerged as the best potting media with the survival percentage of 98.90% with comparative better growth during primary hardening. Simultaneously maximum growth and development including plant height (15.36 cm), number of leaves (5.71), pseudostem girth (3.88 cm), maximum number of roots (5.90), maximum root length (3.69 cm) has been observed during primary hardening. For secondary hardening, eight combinations of substrates were used in conjunction with soil. Among all the treatments in the secondary hardening, SHT4 (soil+ bonemeal; 3:1) along with the application of Jeevamrit have shown highest field survivability (100%). Moreover a maximum shoot length (33.40 cm) has been observed during secondary hardening with maximum number of leaves were recorded (9.25) with pseudo stem girth 6.98 cm. The outcome of the present study suggested that the treatment PHT7 performed better growth during primary hardening. However the treatment SHT4 has shown comparatively higher growth during secondary hardening.

“…To simulate photosynthetic rate, most TBMs used a kinetic enzyme model based on Farquhar–von Caemmerer–Berry (FvCB) ( Farquhar et al., 1980 ; Jin et al., 2023 ). The maximum rate of carboxylation (V cmax ) and the maximum rate of electron transport (J max ) are two key photosynthetic parameters in FvCB model.…”

The leaf maximum rate of carboxylation (Vcmax) is a key parameter of plant photosynthetic capacity. The accurate estimation of Vcmax is crucial for correctly predicting the carbon flux in the terrestrial carbon cycle. Vcmax is correlated with plant traits including leaf nitrogen (Narea) and leaf photosynthetic pigments. Proxies for leaf chlorophyll (Chlarea) and carotenoid contents (Cararea) need to be explored in different ecosystems. In this study, we evaluated the relationship between leaf maximum rate of carboxylation (scaled to 25°C; Vcmax25) and both leaf Narea and photosynthetic pigments (Chlarea and Cararea) in winter wheat in a farmland ecosystem. Our results showed that Vcmax25 followed the same trends as leaf Chlarea. However, leaf Narea showed smaller dynamic changes before the flowering stage, and there were smaller seasonal variations in leaf Cararea. The correlation between leaf Vcmax25 and leaf Chlarea was the strongest, followed by leaf Cararea and leaf Narea (R2 = 0.69, R2 = 0.47 and R2 = 0.36, respectively). The random forest regression analysis also showed that leaf Chlarea and leaf Cararea were more important than leaf Narea for Vcmax25. The correlation between leaf Vcmax25 and Narea can be weaker since nitrogen allocation is dynamic. The estimation accuracy of the Vcmax25 model based on Narea, Chlarea, and Cararea (R2 = 0.75) was only 0.05 higher than that of the Vcmax25 model based on Chlarea and Cararea (R2 = 0.70). However, the estimation accuracy of the Vcmax25 model based on Chlarea and Cararea (R2 = 0.70) was 0.34 higher than that of the Vcmax25 model based on Narea (R2 = 0.36). These results highlight that leaf photosynthetic pigments can be a predictor for estimating Vcmax25, expanding a new way to estimate spatially continuous Vcmax25 on a regional scale, and to improve model simulation accuracy.
