“…GA 3 treated flowers had continuous water uptake this might be due to hydrolysis of polysaccharides and starch into glucose and fructose which decreased the water potential in stem and flower. These results are agreed with Nowak and Mynett (1985) in Lilium and Karimi (2007) in lily.…”

“…Significant difference was observed due to different plant growth regulators for flower diameter. The Maximum flower diameter (16.26 cm) was recorded in the T 10 (GA 3 @200ppm), followed by T 8 (Ethrel@550ppm) with (15.70 cm) and the flower diameter (9.67 cm) was recorded in T 0 (Control@ water spray) [9]. Significant difference was observed due to different plant growth regulators for vase life (days).…”

The present Research was conducted To evaluate the response of lilium by GA3, IAA and Ethrel to analyse the growth and yield under polyhouse in Prayagraj agro climatic condition. The experiment was layout in Randomized block design (RBD) with 13 treatments and each treatment replicated thrice. The experiment was carried out during November, 2021 to February, 2022 in Research Field, Department of Horticulture, SHUATS, Prayagraj. The treatments consist of different concentrations of plant growth regulators (IAA, Ethrel and GA3). From the experimental findings, it was found that the treatment T10 (GA3@200ppm) was found the superior compared to other treatment combination, which recorded highest plant height (71.36 cm), Number of leaves (72.36), plant spread (15.44 cm2), Earliness in first flower bud initiation (44.33 days), Earliness first flower initiation (50.07 days), flower stalk diameter (6.55 mm), number of buds per inflorescence (4.66), Bud length (11.59 cm), Bud diameter (17.07 mm), Flower diameter (16.26 mm), Vase life (10.55 days), Number of spike yield per plant (2.23), number of spike yield per hectare (77142.59).The present research shows that the treatment of (GA3@200ppm) resulted best among remaining Treatment concentations under the Prayagraj agro climatic condition.

“…Mangoes in the groups of 1, 2, 3, 4 and 5 were subjected to the treatments T 1 , T 2 , T 3 , T 4 and T 5, respectively. Similarly, fruits of banana grouped into six groups were subjected separately to the treatments T 1 , T 2 , T 3 , T 4 , T 5 and T 6, respectively.…”

“…Pre-cooling can immediately lower the field heat of commodity following harvest and slow down metabolism and reduce deterioration prior to transport or storage [4,5]. The reduction in temperature has an added advantage in reducing the production and sensitivity of the produce to ethylene that accelerates ripening and senescence [6].…”

Fruits have self defense mechanisms to protect from oxidative stress by the activation of many antioxidant defense enzymes like superoxide dismutase (SOD), catalase (CAT) and peroxidase (POX). The development of oxidative stress in fruit mainly depends upon its cellular antioxidant levels, physical atmosphere of the fruit and its postharvest handling. The present investigation was carried out to study the effect of post harvest pre-cooling and heat treatments on antioxidant enzymes, CAT, POX and SOD involved in detoxification of reactive oxygen species (ROS) were measured in mango var. Alphonso and banana var. Robusta. Increased CAT and POX activities in mango and banana during heat treatment followed by cooling at 8 ºC or 13 ºC indicated increased elimination of ROS. Pre-cooling of mango at 8 ºC showed twofold decreased CAT activity in the pulp whereas heat treatment to mango followed by cooling at 8 ºC and 13 ºC recorded 2.2 fold increased CAT activity. Pre-cooling treatment reduced POX activity whereas heat treatment followed by cooling resulted in decreased SOD activity. CAT activity after pre-cooling to 13 ºC by using precooled air was similar to that of control. In banana, pre-cooling treatment (8 ºC) and heat treatment followed by cooling reduced CAT activity in peel and pulp, whereas POX activity increased. Pre-cooling and heat treatments altered normal homeostasis of these fruits, which were reflected by changes in the levels of antioxidant enzymes-CAT, POX and SOD. Visual assessment of mango and banana fruits after pre-cooling at different temperatures (5 ºC, 8 ºC and 13 ºC) did not show any chilling injury (CI) symptoms. Similarly, application of postharvest quarantine heat treatment (52-55 °C) for 5 minutes to mango showed no heat injury (HI) symptoms like skin scalding, damaged lenticels which could be due to very short duration of exposure. Extent of recommendation of pre-cooling temperature and heat treatment of these fruits after pre-cooling at 5 ºC and 8 ºC can be made based on the levels of reactive oxygen species. The present study showed that the level of expression of antioxidant enzymes got affected during pre-cooling (5 ºC and 8 ºC) and quarantine heat treatment (52-55 °C). Therefore, findings of the present study serve as basic information about cellular homeostasis in the mango and banana.
