“…The percent of abnormal seedlings were reduced significantly when seeds were treated with GA 3 100 ppm (20.03), GA 3 50 ppm (20.43) IAA 100 ppm (20.62) and IAA 50 ppm (20.89) when the control showed 29.79 and GA 3 they showed that 32.76, 31.41, 30.78 and 26.51% decrease in number of abnormal seedlings over control, respectively (Table 2). Similar results were obtained by findings of Natesh et al, (2005) in Chilli, Singh et al, (2006) in Okra, Bateshwar et al, (2008) in Okra, Hilli et al, (2008) in ridge gourd, Nirmala et al, (2008) in beet root, Patil et al, (2008) in Okra, Nagre et al, (2008) in Indian spinach, Patil and Patel (2010) in okra, Nabi et al, (2010) in okra, Rouhi et al, (2011) in soybean, Thapa et al, (2013) in sprouting broccoli, Xu hui chun et al, (2013) in water melon, Mahipat et al, (2013) in mung bean, Vijendra Kumar et al, (2014) in garden rue and Li Weifei (2014) in Robinia pseudoacacia. …”

“…Selection of a priming method is important in harnessing the benefits of priming; the best methodology may vary with crop species. (Nirmala and Umarani, 2008). Hydropriming for 12 hours and solid matrix priming for 24 hour was found to significantly increase seed quality and marketable yield of okra (Sharmaa et al, 2014) indicating that duration of soaking may vary with priming methods.…”

An experiment on seed quality enhancement of common bean (Phaseolus vulgaris L.) var. S 9 (local) was conducted at the department of seed science and technology, OUAT, Bhubaneswar during 2013-14 by use of three biocontrol agents viz. Trichoderma viride, Trichoderma harzianum, Pseudomonas fluorescence. Seeds were bioprimed with the biocontrol agents at 40, 50 and 60 % concentration for 4,8,12 and 16 hours of soaking. Seeds were also hydro primed for 4,8,12 and 16 hours. Unprimed dry seed resulted in germination (69 %), shoot length (27.5 cm), root length (14 cm), seedling dry weight (1.71g), SVI-I (2859.2), SVI-II (118.0) and speed of germination (5.8) while hydro primed seeds resulted in germination (72%), shoot length (31.9 cm), root length (15 cm), seedling dry weight (1.80 g), SVI-1 (3375.9) SVI-II (129.8) and speed of germination (6.7). Trichoderma harzianum at 40% concentration and for 4 hours of soaking resulted enhancement of above quality parameter like 13.0 % in germination, 21.1 % in shoot length, 20.7 % in root length, 31.6 % in seedling dry weight, 36 % in seedling vigour index-I, 48.1 % in seedling vigour index-II and 58.6 % in speed of germination over unprimed seeds. Bio priming with P. fluorescence ( at 40% concentration and for 4 hour) closely followed and at par with best treatment with 11.6 %, 18.2 %, 16.4 %, 30.4 %, 30.7 % and 56.9 % enhancement of above mentioned quality parameters, respectively.

“…The first part of the experiment consisted of standardization of protocol for humid priming of okra seeds. Initially, the okra seeds were soaked in water for 12 h [26]. The soaked seeds were tied in a cloth bags and placed in a container, over an elevated platform so to allow excess water to drain.…”

“…The main objective of the study was to compare the efficacy of different methods of seed enhancement. Therefore, okra seeds were submitted to seed priming protocols viz., (i) hydropriming (12 h) [26] (ii) spin priming (12 h soaking + 4 min spinning), [27] (iii) humid priming (12 h soaking + 4 h humid incubation) (iv) seed coating' (TNAU formulation @ 3 g kg -1 ) [28] and humid priming (12 h soaking + 4 h humid incubation) + seed coating' (TNAU formulation @ 3g kg -1 ). TNAU seed coating formulation developed in the Department of Seed Science and Technology, Tamil Nadu Agricultural University (TNAU) consists of a hydrophilic polymer (79.25 %), pigment (20.00 %), carboxy methyl cellulose (0.50 %) and gibberellic acid (0.25 %) [28].…”

The study was conducted to standardize the methodology of humid priming for improving the seed germination and vigour of okra seeds and to compare the efficacy of different enhancement techniques such as hydro priming, spin priming, seed coating and the combination of ‘humid priming + seed coating’ in improving the seed vigour characteristics of okra (Abelmoschus esculentus L.). In order to standardize the humid priming technique, okra seeds were subjected to humid priming for four different duration’s viz., 2, 4, 6 and 8 h, shade dried to original moisture content and subjected to evaluation of seed germination under shade net conditions in raised beds. The results revealed that 4 h of humid priming was statistically significant to the rest of the durations, with respect seed germination and seedling growth. With respect to anatomical potential, the radicle length (3.39mm), cotyledon length (6.69mm) and cotyledon width (6.30mm), recorded by humid priming (4 h) was 62.2 %, 6.4 % and 2.6 % higher than control seeds. The second experiment conducted to compare the efficacy of hydro priming, spin priming, polymer coating and combination of humid priming + seed coating. The study revealed that seeds subjected to combination of humid priming (4 h) + seed coating (3g kg-1) recorded highest physiological potential in terms of germination percentage (87 %), seedling length (20.2 cm), dry matter production (421.3 mg), vigour index (1765), root volume (3.5 cm3) and root sheath (2.560 g) while the control recorded only 70 %, 15.1 cm, 328.7 mg, 1055, 2.0 cm3 and 1.532 g, respectively.
