PGPR strains exhibiting optimum functional traits at high temperature and are compatible with Rhizobium can be used in pigeonpea as biofertilizer. A total of 45 rhizobacterial isolates were isolated from 13 different locations of pigeonpearhizospheric soil of Punjab. Out of the 45 isolates, 5 isolates selected on the basis of maximum growth at 30°C and 40°C were morphologically and biochemically characterized, belonging to genera Pseudomonas (P-6, P-9) and Bacillus (P-30, P-31, P-32). Selected isolates were further evaluated for the production of IAA, GA, SA and flavonoids. IAA production was estimated in the range from 0.45-25.13 μg/ml and 4.62-34.34 μg/ml in the presence of tryptophan at 30 and 40°C respectively. Maximum gibberellic acid production was recorded with P-30 (108.99 μg/ml and 112.12 μg/ml) at 30 and 40°C respectively. Similarly maximum salicylic acid was also estimated with P-30 (157.2 μg/ml) followed by P-31 (141.0 μg/ml) at 40°C. All the isolates were also found to produce flavonoids ranged from 2.98 - 4.40 μg/ml at 40 °C. Isolates P-30, P-31 showed superior production of growth hormones and flavonoid-like compounds can further be tested under the field conditions to enhance growth and yield of pigeonpea.

Hot Water Dipping

The current research aimed at studying the possibility of improving the postharvest storability of “Nanfeng” mandarins by hot water dipping (HWD) treatment. The research was conducted in two phases. Firstly, two different temperatures (50 and 55°C) were tested for three different dipping durations (2, 3, and 4 min) on the mandarin fruits, and the best combination was defined for the prevention of weight loss and fruit decay. Next, the optimal treatment (HWD at 50°C for 3 min) was used in further studies to test the effects on the postharvest fruit quality attributes. Regular measurements were performed to determine total soluble solid (TSS) content, titratable acid (TA) content, vitamin C (VC) content, total sugar content, respiration rate, malondialdehyde (MDA) content, and activities of superoxide dismutase (SOD) enzyme, polyphenoloxidase (PPO) enzyme, and peroxidase (POD) enzyme. According to the results obtained, HWD treatment was found to prevent the loss of TSS, TA, and VC contents during the storage period. The HWD-treated fruits were also found to have a lower respiration rate and MDA content as compared with control treatment. Furthermore, HWD treatment significantly enhanced the activities of SOD, POD, and PPO which are known to enhance tolerance to lipid peroxidation and are associated with the fruit protection from injuries and pathogens. Present results also suggest that the activation of the SOD and POD enzymes is highly related to the respiratory activities of the fresh produce. This suggests that the HWD can be used to improve the storability of “Nanfeng” mandarins by maintaining the postharvest physical and biochemical quality.

Heat treatment was used to extend the shelf life of postharvest Chaenomeles speciosa (Sweet) Nakai (C. speciosa), its effects on the quality and physiological properties of C. speciosa were studied. The results showed that heat treatment reduced the weight loss, inhibited the decline of titratable acids (TA), maintained a higher activity of peroxidase (POD) and catalase (CAT), compared to untreated C. speciosa. Treatment in hot water dipping at 50℃ for 2-4 min maintained the better quality of postharvest C. speciosa stored at 0℃ for 120 days, which indicated that heat treatment is an effective preservation technology to prolong the shelf life of C. speciosa.

Artemisinin is a sesquiterpene lactone found in Artemisia annua having many medicinal properties. Therefore the factors affecting trichome initiation are important. In the present study, several strategies have been adapted to increase artemisinin production by treating them with nutrients, hormones and elicitors. Abscisic acid, Gibberellic acid (GA3), a combination of GA3+IAA (Gibberellic acid+indole acetic acid), Chitosan, Methyl jasmonate, Acetyl salicylic acid, Lead acetate, sodium chloride, and Nanozime were sprayed on plant at regular intervals. The glandular trichomes of leaves from Artemisia annua (Asteraceae) were examined by light and scanning electron microscopy and the percentage artemisnin content was analyzed by HPTLC. Maximum artemisinin content % and trichome index (0.128) was found when methy jasmonate was applied and minimum artemisinin content % and trichome index was reported in NaCl & acetyl salicylic acid.
