Significant Difference

Chili (Capsicum annuum L.) is an important food additive with high medicinal value. To investigate the effect of plant growth regulators on chili, seedlings of chili were collected from the local market and grown in the experimental field of the University of Barishal, Bangladesh. Foliar spray of different degrees of plant growth regulators, Gibberellin (50 mg/l, 100 mg/l, 250mg/l, 350 mg/l GA3) and Cytokinin (50 mg/l, 100 mg/l, 250mg/l, 350mg/l Kn) were applied from 15 days of germination. Data on different growth and yield parameters were collected and analyzed statistically. The result reveals that there is a significant difference in growth and yield related traits in chili due to the application of plant growth regulators. An optimum level of PGRs application shows better performance compare with control. Plant height particularly influenced by GA3 whereas other attributes like the number of leaves, branches, flowers and fruits are greatly influenced by the application of kinetin.

Strip Intercropping

Background: The shading caused by maize inhibited the growth of soybean, reduced the yield of soybean under maize-soybean relay strip intercropping system. To investigate whether foliar spraying different types of plant growth regulators could improve the growth and yield of intercropped soybean.Methods: A field experiment was conducted in 2018 to evaluate the effect of foliar spraying 6BA (6-benzylaminopurine), S3307 (uniconazole) and DTA-6 (diethyl aminoethyl hexanoate), at the soybean beginning flowering stage, on the growth and yield of three soybean varieties (i.e., Nandou 25 (ND25), Gongqiu 8 (GQ8) and Guixia 3 (GX3)).Result: The leaf area index of three soybean varieties were highest in DTA-6 at 35 days after spraying (DAS) and no significant difference (p less than 0.05) were observed among three plant growth regulators. The chlorophyll a and chlorophyll b content under 6BA and DTA-6 treatments were significantly higher than CK and S3307 at 35 DAS. The activities of antioxidant enzymes (i.e., SOD (Superoxide dismutase) and CAT (Catalase) and antioxidant substances (i.e., GSH (Glutathione) were increased after spraying 6BA, S3307 and DTA-6 in three soybean varieties at 35 DAS. Independent soybean varieties, foliar spraying 6BA, S3307 and DTA-6 increased the soybean yield, pods per plant, 100-grains weight and grain per plant and the effect of DTA-6 (60 mg l -1) treatment were best than others.

Shoot buds originated directly on cotyledon explants of <em>Capsicum annuum</em> L. cv. Kujawianka, when Linsmaier and Skoog medium was enriched with BAP (2 mg/l). Kinetin (2 mg/l) or kinetin with IAA (1 mg/l + 1 mg/l) induced indirect shoot buds regeneration from callus. Rooting was obtained with explants cultivated on a medium containing NAA (0,5 mg/l). Occurrence of the early stages of differentiation was proved at the histological level.

The Impact

This research was conducted to study the impact of foliar spraying by some plant growth regulators to increase salts tolerance of date palm (Phoenix dactylifera L.) cv. Shakar. Thirty young date palm trees (seven years old) and same number of fruiting trees (18 years old) were selected and spraying with naphthalene acetic acid (NAA) solutions at the concentrations (0.50, 100 and 150 ppm), Salicylic acid (0, 0.25, 0.50, and 1.0 mM) and putrescine (0, 0.025, 0.050, 0.1 mM). Results indicated that the application of growth regulators led to reduction trunk diameter comparing with control (121.33 cm). Spraying NAA with concentration of 100 ppm, gave the highest height of the offshoots and a significant difference from the rest of the treatments (253.70 cm). Spraying putrescine with 1.0 mM concentration led to a significant increase in the number of leaves (fronds) as it increased to 24.33 leaf/offshoot, and leaf area which reached 691 cm2. Application of 0.25 mM Salisylic acid increased the number of bunches under saline conditions amounted to 12.67 bunch as well as increased the weight of the fruit to 8.82 g, which differed significantly from the control which gave 7.37 g. As for the size of the fruit, it was found that Spraying of NAA with 100 ppm led to increase the size of the fruit under saline conditions (8.67 cm). We can conclude that the spraying date palm with the above plant growth regulators under saline conditions can lead to increasing absorption of nutrients and subsequent growth and yield improvement.
