Influence of Growth Regulators on Shedding of Broad Bean, Growth, Yield and Seed Quality

In order to study the effect of foliar spraying of growth regulators on growth,seed yield and seed quality, two field experiments were conducted at an extensive field during 2014/2015 and 2015/2016 seasons to determine following foliar spraying of Naphthalene Acetic Acid (NAA) concentrations, i.e. 0, 20, 40 and 60 ppm and Kinetin (Kin) concentrations, i.e. 0, 15, 30 and 45 ppm after 35 and 50 days from sown. Accumulative NAA levelsof to 60 ppm significantly increased total chlorophyll, plant height (cm),branches number/plant, number of shedding flowers, shedding %, pods and seeds number/plant,seedsnumber/pod, seed yield/plant, 100-seed weight (g), seed yield (ton/ha) and protein % in both seasons.Naphthalene Acetic Acid foliar spraying up to 60 ppm exceeded of total chlorophyll, plant height (cm), branchesnumber/plant, number of shedding flowers, podsnumber/plant, seedsnumber/pod, seedsnumber/plant, seed yield (g) /plant, 100-seed weight (g), seed yield (ton/ha) and protein % by 11.47, 23.92, 92.88, 20.53, 11.87, 23.48, 14.16, 24.91, 26.15 and 13.23%, respectively as the average of both seasons. But, reduced the shedding percentage by 11.91% as the average oftwo seasons. Kinetin (Kin) foliar spraying up to 45 ppm significantly increased total chlorophyll, plant height (cm), number of branches/plant, number of shedding flowers, shedding %, pods and seeds number/plant,number of seeds/pod, seed yield/plant, 100-seed weight (g), seed yield (ton/ha) and protein % in both seasons. It could be noticed that foliar spraying of Kinetin (Kin) concentrationsup to 45 ppm exceeded total chlorophyll, plant height (cm), branchesnumber/plant, number of shedding flowers, podsnumber/plant, seedsnumber/pod, seedsnumber/plant, seed yield /plant, 100-seed weight (g), seed yield (ton/ha) and protein % by 12.16, 19.39, 61.64, 5.60, 5.56, 6.96, 5.64, 18.75, 13.38 and 4.39%, respectively as average of both seasons. But, reduced the shedding % by 14.73 % as the average of both seasons.It could be recommended that foliar spraying of Naphthalene Acetic Acid up to 60 ppm and Kin of 45 ppm improved seed yield/ha by 38.2% compared without foliar application

Effect of Growth Regulators and Micronutrients on Fruit Quality in Pomegranate

A field experiment was conducted at Fruit Research Farm of Haryana Agricultural University, Hisar to evaluate the effect of micronutrients and plant growth regulators on fruit quality in pomegranate cv. Jodhpur Red. The treatments comprising of two micronutrients (H3BO3 & ZnSO4 at 0.20, 0.40, 0.60 %), two growth regulators (2,4-D & NAA at 10, 20, 40 ppm) and water were applied fifteen and thirty days after fruit set. Application of 2,4-D at 40 ppm resulted in more total soluble solids. H3BO3 resulted in more ascorbic acid content when applied at fifteen days after fruit set. 2,4-D when applied at fifteen days after fruit set, significantly increased reducing sugar content. Application of micronutrients and growth regulators applied fifteen days after fruit set was more effective in improving fruit quality as compared to thirty days after fruit set

Effect of Media and Growth Regulators on the Propagation of Nyawai (Ficus Variegata Blume) Shoot Cutting)

Forest timber plantation of nyawai (Ficus variegate Blume) established by using vegetative propagated seedling from superior individu is very potential to develop for fulfilling the raw material demand of wood processing industries. The purpose of research was to get the optimum rooting medium and growth regulator concentration for rooting shoot cuttings of nyawai. Materials cuttings were provided from seedlings at 12 months age. The experiment was performed as factorial in a completely randomized design with two factors, i.e. rooting media factors (sand, mixed coconut coir dust + rice husk (2: 1, v/v), and mixed coconut coir dust+ husk rice + husk rice charcoal (6: 3: 1, v/v)) and IBA growth regulator concentrations (0, 50, 100,200,400, 600, and 800 mg/l), with three replications so that twenty experimented unit were used at each replication. Rooting percentage, root number, root length, shoot length, root biomass, shoot biomass, and leaf number were evaluated. Based on the result, sand media produced the highest rooted cuttings (88.10%), while the use of IBA showed the trend to increase the number of root with increasing the concentrations, but it influenced to reduce the shoot growth. Combination treatment of sand media and IBA 800mg/l provided the highest rooted cuttings (93.33%) with the number of root 21. Therefore, for the successful propagation of nyawai, cuttings are planted in sand media with IBA 800 mg/l

ZINC-FINGER interactions mediate transcriptional regulation of hypocotyl growth in Arabidopsis

Integration of environmental signals and interactions among photoreceptors and transcriptional regulators is key in shaping plant development. TANDEM ZINC-FINGER PLUS3 (TZP) is an integrator of light and photoperiodic signaling that promotes flowering in Arabidopsis thaliana. Here we elucidate the molecular role of TZP as a positive regulator of hypocotyl elongation. We identify an interacting partner for TZP, the transcription factor ZINC-FINGER HOMEODOMAIN 10 (ZFHD10), and characterize its function in coregulating the expression of blue-light–dependent transcriptional regulators and growth-promoting genes. By employing a genome-wide approach, we reveal that ZFHD10 and TZP coassociate with promoter targets enriched in light-regulated elements. Furthermore, using a targeted approach, we show that ZFHD10 recruits TZP to the promoters of key coregulated genes. Our findings not only unveil the mechanism of TZP action in promoting hypocotyl elongation at the transcriptional level but also assign a function to an uncharacterized member of the ZFHD transcription factor family in promoting plant growth
