Although nursery lettuce information is plentiful, the use of exogenous cytokinin (6, benzyl amino purine, BAP) as a plant growth regulator, which would increase vegetable nursery yield has only recent suggested. On the other hand, biomass relationships between plug cell volumes, BAP uses and main temperature during nursery is quite scarce. Our results showed that the growth response of lettuce seedlings during nursery is firstly related to mean air temperature, independently the environmental characteristics of the cultivar tested. From the view of a nursery grower, yield can be optimize when higher plug cell number per tray was used or a BAP spray was applied to limited plug trays (128- or 288-cells). One of the novelty result of this work reside in the objective protocol proposed (the marginal root dry weight accumulation rate) to decide the time to transplant. Finally, our results showed that plug purchaser would be change their visual criteria when they buy BAP-treated lettuce for increased field yield.

An experiment was conducted to study the effect of plant growth regulators namely jasmonic acid (50 µM), brassinolide (0.5 ppm), salicylic acid (100 ppm), ascorbic acid (100 ppm), gibberellic acid (10 ppm), benzyl amino purine (5 ppm) and nutrient consortium (K2SO4 (0.5%) + FeSO4 (0.5%) + Borax (0.3%) and TNAU Pulse Wonder (1%) on blackgram (Vigna mungo L.) variety TNAU (Blackgram) CO 6 under salinity condition. The salinity was imposed by 125 mM NaCl concentration in pot culture. Plant growth regulators and nutrient consortium were used as foliar spray at 20 and 40 days after sowing except jasmonic acid, which used as seed soaking. Under salinity stress, water potential, relative water content (RWC), photosynthetic rate, chlorophyll index and yield were significantly reduced as compared to control. Among the treatments, brassinolide and TNAU Pulse Wonder showed supremacy to enhance water potential, RWC and yield compared to other treatments. Salicylic acid performed better to stabilize the photosynthetic rate under salinity followed by TNAU Pulse Wonder. Benzyl amino purine had higher chlorophyll index than other treatments. Increased catalase activity was observed in brassinolide treated plants followed by salicylic acid and ascorbic acid under salinity.

Ornamental cabbage and kale (Brassica oleracea var. acephala L.) plants of cultivars `Osaka White' and `Nagoya Red' were treated with paclobutrazol and uniconazole as foliar sprays or soil drenches. These treatments were compared to the industry standard of daminozide foliar sprays. Ten plant growth regulator (PGR) drench treatments (in mg a.i./pot) were applied 22 days after potting: paclobutrazol at 1 to 16 and uniconazole at 0.125 to 2. Thirteen PGR foliar sprays (in mg/L) were also applied: paclobutrazol at 5 to 80, uniconazole at 2 to 32, daminozide at 2500, 2500 (twice, with the second application occurring 14 days later), or 5000, and an untreated control. Applying drenches of paclobutrazol at 4 mg or uniconazole at 0.5 mg controlled height by 16 to 25%, but at the cost of $0.11 per pot would not be economically feasible for growers to use. Paclobutrazol foliar sprays at concentrations of up to 80 mg/L were ineffective in controlling plant height and diameter of either `Osaka White' or `Nagoya Red'. Uniconazole foliar sprays between 2 and 8 mg/L were effective in controlling height (by 19%) and diameter (by 15%) as daminozide foliar sprays of 2500 mg/L, sprayed twice, with a cost to the grower of $0.02 per pot.
