| Abstract/Description: | The present study was conducted to evaluate the effect of various chemicals (paclobutrazol, KNO3, Prohexadione Ca, salicylic acid, KH2PO4, and spermidine) and girdling on plant growth, tree physiology, fruit yield, and quality in litchi cv. China. Experimental results revealed the least increase in the tree height (1.58%) after spraying of KNO3. Girdling significantly increased the tree girth (3.55 %) and trunk cross-sectional area (7.29%). All the treated trees had 20-50% more leaf relative water content (RWC) than that of the control trees. Paclobutrazol (PBZ) application and a spray of KH2PO4 recorded the maximum value of the stomatal conductance (gs) and transpiration rate (E) at the flower bud differentiation stage. The untreated trees had low stomatal conductance (gs), transpiration rate (E), and internal CO2 concentration (Ci). The transpiration rate was observed to be higher during flowering than during the FBD stage. PBZ application showed the highest free proline and total phenol contents in leaves. The water use efficiency (WUE), mesophyll efficiency (ME) and carboxylation efficiency (CE) was found to be high during flowering compared to the flower bud differentiation (FBD) stage. The Pro-Ca showed the maximum WUE followed by the application of KNO3. Highest number of floral panicles (3656) and yield(2427 fruits /tree & 55.42 kg/tree) were recorded with the spray of KNO3 followed by girdling. The colour intensity of fruits was improved a lot in terms of hue, value, and chroma. |
