“…Bangal, et al, (1982) [57] stated the use of CCC for checking abscission of flowering and also, modifying crop canopy structure. Similar results with PGRs have been found by Thavaprakash, et al, (2006); Kandil, et al, (2011); Khalil, et al, (2006); [58,59,60,61]. Ibrahim, et al, (2007) [62] reported in faba bean (Vicia faba L.) that application of benzyl adenine (BA), IAA or ancymidol reduced flower abscission percentage significantly.…”

India ranks first both as producer and consumer of pulses. It is also the largest importer of pulses as the total domestic requirement outweighs total production. So, to attain self-sufficiency in terms of pulse production the constraints in cultivation need to be addressed. Pulse production faces a series of constraints which include its inherent physiological limitations. These limitations include lower germination percentage, source limitation, low leaf area development, indeterminate growth habit, C3 photosynthetic apparatus, slow initial dry matter accumulation, limited photosynthesis, hormones inhibitors, decline in nodule activity and diversion of metabolic energy to sinks for protein synthesis. To overcome these limitations simple agronomic techniques such as application of growth hormones are adopted. This paper critically reviews the physiological constraints of pulses and effect of growth regulators to improve these limitations and concomitantly increasing yield.

“…Plants that produce maximum flowers within two to three weeks after flowering also show higher pod yields in mungbean and groundnut (Mondal and Hamid 1998;Mondal, 2007). Apart from the magnitude, duration of flowering is equally important since more than seventy per cent of pods plant -1 originate from the first 10-15 days of flowering in soybean (Yoshida et al, 1983;Nahar and Ikeda, 2002;Islam et al, 2010), Vicia faba (Clifford et al, 1990), pigeonpea (Fakir, 1997), and mungbean (Mondal et al, 2009). Pod yield is determined basically by the number of flowers that set in to the pods.…”

The effect of flowering pattern and floral abscission on the yield and yield attributed characters of French bean varieties were studied in a field of Bangladesh Agricultural Research Institute, Gazipur. There nine varieties were treated- (1) BARI Jharsheem-1 (2) BARI Jharsheem-2 (3) Sylhet local-1 (4) Sylhet local-2 (5) Sylhet local-3 (6) Sylhet local-4 (7) Sylhet local-5 (8) Sylhet local-6 and (9) Sylhet local-7. Among the treatments, the highest number of flower was recorded within 5 to 8 days in BARI Jharsheem-2 although, the maximum flower opened within 5 to 8 days and following ceased within 15 to 20 days after first flowering. The total number of flowers per plant varied between 19.36 to 45.06 and 22.0 to 47.20 in two consecutive years while percentage of pod abscission varied between 70.53 to 82.26 and 73.46 to 80.75 in two consecutive years. The maximum yield of French bean was obtained from BARI Jharsheem-1, however identical yield was obtained from BARI Jharsheem-2 treatment. The flowering pattern and percent abscission as well greater number of pod were found to be the influential character for the highest yield of French bean. In addition, seed yield was strongly correlated to the number of opened flowers as well as number of mature pods. Int J Appl Sci Biotechnol, Vol 3(3): 483-489

“…In addition, a two-year field experiment (1985 and 1986) on field peas ( Pisum sativum L.) in Western Australia showed that the first three podding nodes contributed the most to yield compared to the subsequence nodes [ 37 ]. In other studies, over 70% of pods per plant were set in the first 10–15 days after flowering in faba bean [ 38 ], soybean ( Glycine max L.) [ 39 , 40 ] and pigeon pea ( Cajanus cajan L.) [ 41 ]. To sum up, the early period of the flowering phase is the time for forming pods, and it is the most critical time in which pod sets may be most harmed by low temperatures, leading to a significant yield loss.…”

Frost is one factor that causes extensive yield losses globally. A study was conducted to evaluate frost damage under field conditions and assess the genetic variation of flowers converting into pods. Diverse faba bean genotypes were evaluated under four growing seasons in a randomized complete block design: three at the University of Sydney, Narrabri, Australia (2014–2016) with three sowing dates, and one at the Agricultural Research Station, Dirab, Riyadh, Saudi Arabia (2016/2017) in one sowing. Visual methods were used to estimate frost damage and record the development of pods. Radiation frost in 2014 (Narrabri) damaged lower pods, while advection frost in 2016/2017 (Dirab) damaged upper pods. The radiation frost formed immediately above the ground; therefore, flowers and pods of taller plants minimized the damage because of their long distance from the ground. The earliest (mid-April) and middle sowing (May 7) suffered more by frost, while a delay in sowing (last week in May) led to frost escape or minor damage. The genotypes IX474/4-3 and 11NF010a-2 showed low sensitivity to frost at the vegetative and reproductive stages. Flowers developed at the beginning of flowering had a faster and higher pod formation rate (41–43%) than those formed later and contributed more to yields. Therefore, a severe frost at the beginning of flowering can cause a significant yield loss as these flowers are the most productive. The frost-tolerant genotypes, and faster and higher pod forming rates, identified in this study can be exploited to breed better varieties in the future.
