Growth Regulators for Yield and Quality Enhancement in Litchi (Litchi chinensis L) - A Review

“…In pericarp of litchi in many cultivars (Erdanli, Huaizhi and Feizixiao), it was observed that the concentration of cytokinins was high in early blooms and a high CTK: ABA ratio favoured fruit growth in all cultivars of litchi (Li et al, 2005). Chen (1990) found highest levels of cytokinins in Heh Yeh cv of litchi trees in the xylem sap which reached maximum during flower bud formation and full bloom.…”

3-Hydroxy-3-methylglutaryl coenzyme A reductase 1 (HMG1) is highly associated with the cell division during the early stage of fruit development which determines the final fruit size in Litchi chinensis

“…In small avocado fruit reduced HMGR activity was associated with an increased mesocarp ABA concentration, and an imbalance in the ratio of CK/ABA would be expected to reduce cell division and fruit size (Moore-Gordon et al, 1998). In litchi, fruits of large-fruit pheno-or genotype obtained a higher CK/ABA ratio than those of small-fruit pheno-or genotype correspondingly during early stage of fruit development (Li et al, 2005). Thus, it is plausible that LcHMG1 plays an efficient role in maintaining the sterol biosynthesis and the hormone homeostasis which are vital for cell division during early fruit.…”

Seedling establishment of two shrubby plants native to the Sierra Nevada mountain range

“…In addition, Cks also help diminish the inhibitory activity of abscisic acid (ABA) and promote seed germination [16][17][18]. Numerous kinetin derivatives, such as BA or Benzylaminopurine, in which the furfuryl group is replaced by other groups, also stimulate germination [19,20].…”
