Introduction The key role in the control of the numer of flowers nd pods per legume plnt is plyed to numer of fctors demonstrting comprehensive effect; most importntly, the wether conditions pttern [9,17], plnt nutrition [1], competition for ssimiltes etween vegettive nd genertive plnt prts [12] nd their hormonl economy [2]. 674

Borowsk nd Prusiński: Effect Of Tricontnol On The Productivity Of Yellow Lupin (Lupinus... Tricontnol (TRIA) is 30-cron sturted lcohol cting s growth regultor [8]. Applied t very low concentrtions for legumes, it ffects mny physiologicl processes, e.g. it triggers net ssimiltion nd the ctivity of nitrte reductse, increses the contents of leghemogloin in nodules nd N in leves nd in seeds [11], which enhnces yielding [3,6,10,13,18]. The working hypothesis of the present reserch ssumes tht folir ppliction of tricontnol will increse the plnt supply with nitrogen, nd thus limit flower nd podsets shedding in yellow lupin plnts, enhnce yielding nd the iologicl use of the plnt potentil. The im of the present reserch ws to determine the optiml dose nd dte of tricontnol ppliction in yellow lupin seed production. Mterils nd methods A two-fctor field experiment under strict conditions in rndomised lock design in 4 reps ws mde over 2007-2009 t the Mochełek Experiment Sttion of the Fculty of Agriculture nd Biotechnology, the University of Technology nd Life Sciences in Bydgoszcz (Polnd). The reserch investigted trditionl (non-selfcompleting) yellow lupin cultivr, Mister. Tricontnol (TRIA) ws pplied t two plnt development stges: t the eginning of looming on the min stem nd on lterl shoots t three concentrtions determined ccording to literture reports: 0.5 mg. dm -3 low, 1 mg. dm -3 verge nd 2 mg. dm -3 high. The control involved plnts sprying with wter t oth development stges [3,10]. The experiment ws set up fter corn grown for silge on the soil of good rye complex, of n verge content of phosphorus nd high content of potssium nd ph 5.6. In spring there were pplied phosphorus potssium fertilistion t the doses of 80 kg P 2 O 5. h -1 nd 100 kg K 2 O. h -1 s well s Nitrgin for lupin. The Srfun 65 DS-dressed-seeds were sown in successive reserch yers on April 4, 7 nd 8, 3-4 cm deep t the 20 cm row spcing using the Oyord plot drill. The sowing plot re ws 16.8 m 2 nd the hrvest plot re 13.2 m 2. Directly fter sowing Aflon 450 SC ws used to control dicotyledonous weeds t the dose of 1.25 dm 3. h -1, nd fter plnt emergence, t the 3-4 lef stge hrrowing ws performed twice cross the rows. In 2007 nd in 2009 t the udding phse the plnts were spryed with Srfun 500 SC ginst nthrcnose. Sprying with tricontnol followed the experiment design t the eginning of looming on the min stem (respectively in the reserch yers: on June 9, 12 nd 26) nd on lterl shoots (in respective reserch yers: on June 19 nd 20 s well s July 10) in 400 dm 3. h -1 of wter. For the control plots the flowers were counted for 20 plnts, twice for ech plot: t full looming of the min stem nd then on lterl shoots. Prior to hrvest from ech plot there were rndomly smpled 20 ech to define the structurl yielding components, nmely the numer of pods nd seeds, the seed weight, the seed numer nd weight per pod s well s the 1000 seed weight. The seed hrvest ws performed with 675

In 2007 nd 2009 wrm nd riny wether over the vegettive nd genertive development enhnced undnt looming nd pod setting, while semi-dry conditions t the end of July nd t the eginning of August - plnt ripening. However, n lmost two-fold higher totl rinfll, s compred with the multi-yer period, in July 2009 prolonged the plnt ripening nd the period of the vegettion to 145 dys. The wether conditions in 2008 were extremely unfvourle to lupin, especilly t the initil growth period nd then t the genertive stge. Strting from the third decde of April to mid July semi-drought nd drought occurred; the verge totl rinfll t tht time ws much lower thn the multi-yer men. Under such conditions lupin plnts ripened lredy fter 115 dys of vegettion. Results A vried wether conditions pttern over the reserch yers ffected considerly the genertive growth of yellow lupin plnts nd their yielding. Under fvourle moisture conditions in 2007 nd 2009 the coefficient of the use of iologicl potentil expressed s the quotient of the numer of pods on the hrvest dy nd the numer of flowers developed on the min stem ws, respectively, 28 nd 29%, nd in worse conditions, s fr s precipittion is concerned, in 2008 only 20% (Fig. 1). On lterl shoots, its vlue rnged from 0 in 2008 to 12.3% in 2009 (Fig. 2). Interestingly, the verge numer of developed flowers did not differ considerly nd it ws, respectively, on the min stem nd lterl shoots in successive reserch yers: 28.5 nd 20.2; 26.7 nd 11.7 s well s 32.5 nd 25.0. However, irrespective of the moisture conditions in ll the reserch yers, incresing TRIA doses incresed the vlue of the coefficient of use of the iologicl potentil, especilly on the min stem. % 40 35 30 28.4 39.3 34.0 36.8 32.3 34.8 29.2 29.2 26.6 20.6 22.1 36.6 25 20 15 10 5 0 2007 2008 2009 0 0,5 1,0 2,0 mg. dm -3 TRIA Fig. 1.

The totl precipittion optiml for lupin in the vegettive period rnges from 350 to 400 mm [17], while the gretest wter requirements, esides the seed germintion stge, coincide with looming nd pod-setting, nd the drought over tht period hs very unfvourle effect on the yielding of ll the legumes. Under precipittion deficit in 2008 the plnts set less pods (no pods on lterl shoots t ll), which did not mke full use of the production potentil possile nd resulted in very low yielding (1.14 t. h -1 ). The yers 680

From the point of view of seed producers, high iologicl potentil mesured with the numer of developed flowers is not used y the yellow lupin plnts enough since considerle prt of genertive orgns (flowers nd podsets) shed still efore ripening [1,2,12]. According to Byszewski [5], the verge numer of flowers per yellow lupin plnt cn rech even 65, while the numer of pods on the hrvest dy rrely exceeds 15 (e.g. 24% of flowers), nd the seed yield 2 t. h -1. Similrly the results reported y other uthors point to low use of the iologicl potentil of different lupin species [7,16]. In the present reserch the numer of flowers per plnt over the reserch yers ws strongly differentited y moisture conditions during vegettion period nd rnged from 38.4 to 57.5. However the verge vlue of the coefficient of use of the iologicl potentil on control plnts (with no TRIA pplied) ccounted for 25.6% on the min stem nd 5.4% on lterl shoots nd ws. On verge the TRIA doses incresed its vlue up to 32.2% nd 6.71%, nd this effect ws oserved in ech yer of experiment. The externl ppliction of growth regultors cn, t lest prtilly, limit lupin flower nd podsets shedding [4,14,15]. Once tricontnol ws invented, mny reserchers found its significnt effect on the enhncement of yielding of vrious legume species, e.g. chickpe [18], common en [4,6], mung en [10], cowpe [11] nd lentil [13]. The results otined in the present reserch showed tht ppliction of TRIA t ll the concentrtions significntly incresed yellow lupin yielding. Under unfvourle conditions the highest seed yield ws otined following ppliction of 2.0 mg. dm -3 TRIA dose, wheres under wether-fvourle condition, the low (0.5 mg. dm -3 ) or medium (1.0 mg. dm -3 ) dose incresed the seed yield significntly s compred to the control. Similrly fvourle results of TRIA were reported y Biernum et l. [3], however the seed yield increse depended on the TRIA dose nd it ws cultivrspecific. Vried yield-forming effects, dependent on the concentrtion of tricontnol, were lso reported y Kumrvelu et l. [10] oserving significnt increse in the mung en seed yield fter the folir ppliction of TRIA t the concentrtion of 0.5 mg. dm -3, however, significnt decrese when 2.0 mg. dm -3 TRIA ws pplied. Significntly est yield-forming effects in growing chickpe [18] nd common en [6] were noted following the ppliction of 4.0 mg. dm 3 of tricontnol. In the present reserch there ws lso oserved significnt increse in the vlue of structurl yielding of plnt components the numer of pods nd seeds s well s the seed weight per plnt fter the ppliction of incresing TRIA concentrtions. However TRIA doses did not ffect vlues of seed yield elements on lupin rnches. The most fvourle effects on those chrcters were recorded fter the use of 2 mg. dm -3 TRIA, while Kumrvelu et l. [10] noted tht 0.5 mg. dm -3 TRIA significntly increses the numer of pods nd seeds per plnt s well s the seed weight per pod in mung en. Most reserch into the use of TRIA in growing griculturl nd vegetle crops s well s ornmentl plnts were mde in Asi nd it is where the regultor is 681

In Polnd numer of experiments hve een reported into the ppliction of vrious growth regultors to enhnce the use of the production potentil y legumes, however, none hs een lunched in griculturl prctise. Exceptionlly promising reserch results into tricontnol in growing yellow lupin for seed definitely cll for further experiments, lso into other legume species nd under vrious gro-climtic conditions. Summing up, tricontnol significntly incresed yellow lupin yielding, however, the TRIA yield-forming effect mostly depended on the totl precipittion nd its distriution. Under more fvourle moisture conditions the concentrtion of 0.5-1 mg. dm -3 ws sufficient nd under less fvourle 2 mg. dm -3. A higher yellow lupin productivity resulted from fvourle effect of tricontnol on the increse in the vlue of the coefficient of use of the iologicl potentil of the plnts, especilly on the min stem. The incresing TRIA concentrtion lso significntly incresed the vlue of structurl lupin yielding components, except for the 1000 seed weight. There ws found significnt effect of the TRIA ppliction dte neither on yellow lupin yielding nor on the structurl seed yield components.
