“…This technique has been employed by (Reichel et al 2010) for classification of harvest maturity of lychee fruit in terms of its quality changes during cold storage, and by using this analysis, it was realized the differentiation of four maturity classes from premature to full-mature lychee fruit. PCA was carried out in this study to visualize the trends or clusters among samples from their spectral profile.…”

Hyperspectral imaging (HSI) technique has shown promise as a rapid and nondestructive tool to evaluate various internal quality attributes of fruits and vegetables. The objective of this study was to investigate the nondestructive prediction of soluble solids content (SSC) and pH of lychees and maturity discrimination. Two hyperspectral imaging systems of visible/short-wave near infrared range (600-1000 nm, Spectral Set I) and long-wave near infrared range (1000-2500 nm, Spectral Set II) were employed. Results showed that Spectral Set II (SSC: r p =0.877, RMSEP=0.911°Brix; pH: r p =0.745, RMSEP=0.291) performed better than Spectral Set I (SSC: r p =0.790, RMSEP=1.279°Brix; pH: r p =0.701, RMSEP=0.308) for the internal quality prediction of litchi and maturity discrimination. The partial least square discriminant analysis (PSL-DA) model had a discrimination rate of 90.63 % for Spectral Set I and 96.88 % for Spectral Set II. β-Coefficients of partial least squares regression (PLSR) models were used to choose optimal wavelengths for quality predictions. The performance of optimized PLSR in both spectral sets were comparable to the models developed using the whole spectral range.

“…Changes in PPO activity during maturation have been described for several fruits, including apple, apricot, banana, grape, litchi, mango, melon, olive and also peach . In most cases, PPO activity progressively increases as fruit matures, experiencing the highest rise in the last days before harvest.…”

“…When fruit attained the equal edible ratio at 70% in 'Early Big' (at 11 weeks AFFB) like its maternal parent 'Sah Keng' [23], the TSS/TA ratio in the juice of 'Early Big' fruit had already reached 28 ( figure 3), which meets the requirement for trade, as suggested by Underhill and Wong [21] ( figure 3). For other litchi cultivars, such as 'Brewster' [24], 'Hong Huey' and 'Chacapat' [25], different values of the sugar/acid ratio in juice, ranging from 15 to 30, were recommended for fruit maturity evaluation due to different analysis methods used in the studies [25]. Early-season cultivars generally bloom earlier [26].…”

-Introduction.A short harvest window is common in litchi production worldwide, leading to imbalance between supply and demand for fresh fruit. This problem can be mitigated with early-maturing cultivars, such as 'Early Big', released in 2010 in Taiwan. Our goal was to characterize the generative development in this novel litchi cultivar. Materials and methods. The patterns of female flowering and fruit development, and fruit abscission were investigated in 'Early Big' litchi in 2013 and 2014. The relationship between the second round (2 nd R) blooming and the first round (1 st R) fruit was studied. The ambient temperature in both years was recorded. Results and discussion. 2-3 weeks after full female bloom (AFFB) the 2 nd R flowering occurred, followed by fruit abscission with loss of 95% fruit within 4 weeks AFFB in 'Early Big' litchi, resulting in low yield at harvest. The 2 nd R blooming was negatively correlated with the 1 st R fruit retention rate from week 4 AFFB in 2013. Overall, the period of low temperature from November through to the following March was longer in 2013/2014 than in 2012/2013. The trait of early maturing in 'Early Big' is mainly due to early flowering. Temperature may be related to the generative development in 'Early Big'. The accumulation of low temperature in early spring may be related to poor initial fruit set. Conclusion. The presence of 2 nd R flowering also potentially reduced the 1 st R fruit set and retention. These issues must be addressed to develop field strategies to improve yield in 'Early Big' litchi.
