Plant Growth Substances in Crop Production: A Review

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

“…The increase in seed yield/plant due to foliar spraying of Naphthalene Acetic Acid could be attributed to the more increases in vegetative growth characters, which might provide more vegetative area and increases pod set%, reduction in abscission %, increasing the seed number/pod, as mentioned by [18].These results are in agreement with those described by [6,8,10,11,12].…”

“…It could be summarized that the aptitude of cytokines and NAA to mobilize assimilates to the area of request is accountable for enhanced fruit set and seed productivity [19].Foliar spraying with growth regulators, enhanced expression and forms into SOD indicate the possible participation in growth regulators in delaying the membrane deterioration during abscission leading to increased fruit set [20].Seed yields and its attributes i.e. number of pods/plant, pods yield /plant, 100 seed weight, biological yield/plant and protein yield/ha were significantly better with application with 50 mg/l IAA + 75 mg/l Kinetin [13].These results are in harmony with [10,11,12,13].…”

“…100-seed weight (g). 10. Seed yield (ton/ha): whole plants produced from the three inner ridges of each plot were harvested and left to dry in the air, then they were threshed and the seeds (which were at 13 % moisture) were weighted (kg), then converted to (Kg/ha).…”

“…Naphthalene Acetic Acid belongs to synthetic forms of Auxins [3].Spraying of Naphthalene Acetic Acidimproved plant height, fruit set with increases in seed yield/ha [4].Sprayingtwiceof growth regulators improved the number of pods/plant, pod weigh/plant and increased seed yield by 17.7% compared without growth regulator foliar spraying [5].Application of Amcotone at 600 ppm (NA+NAA),decidedlyaugmented plant height, leaf area index, flowering set, seed yields and its attributes [6].The growth promoter NAA enhanced the mobilization of photo assimilatesinto filling seeds [7].Foliar spraying of Kinetin significantly enhanced plant growth and growth even grown under ecologicalworry. He added that foliar spraying of Kinetinenhanced flowering and delays leaves senescence [8].Foliar application of Vicia fabaplants with indel-3-acetic or gibberellin increased the number of branches/plant and number of pods/plant [9].Plant growth substances are enhanced the source-sink relationship and increase the translocation ofphoto-assimilates to sink,formerlyenhanced flower formation, fruit and seed development and improving seed production [10].Foliar sprays with Oraset-x Naphthalene Acetic Acid significantly the superior treatment to produce plants with vigorous vegetative growth, i.e. plant height and number of branches/plant, earliness, highest fruit set percentage, total green yields, number of pods/plant, weight of ten pods, pod characters, weight of 100 green seeds and total protein [11].The highest numbers of shedding flowers and shedding percentage% were obtained the control.…”

The Effect of Leaves Extract of Mentha Sp. and Zizyphus Sp. on the Growth of Vigna Sp.

“…and the rate of 33.50, as for the number of branches are significant affected in the treatment of Ziziphus Mill. concentration of 20%, with an increase in this treatment and at the rate of 40.00, due to the increase in the number of sheets and the number of branches to efficient of photosynthesis and increase of plant material (12,13). Table 3 indicates that the plant's height was significantly affected, with an increase in the treatment of Ziziphus Mill.…”
