Abstract
A study was performed on the effect of various concentrations of IAA, 2,3,6-triiodobenzoic acid, and maleic hydrazide, supplied to Richter’s nutrient solution, on growth of pea plants in water cultures. After a 18-day cultivation growth was evaluated and in the plants gathered the content of total N, P, K, and Ca was estimated.
Growth of experimental plants (as evaluated from fresh and dry weight) was affected by all three regulators in dependence on the concentration used. It was stimulated by lower concentrations and inhibited by higher, the production of both fresh and dry weight of the root system being stimulated by all IAA concentrations used.
The ratio of root dry weight to that of the entire plant was markedly increased after application of IAA and 2,3,5-triiodobenzoic acid, whereas when applying maleic hydrazide it was only slightly increased in comparison with control.
Stimulation or inhibition of growth induced by IAA treatment was accompanied by an accordingly increased or decreased accumulation of N, P, K, and Ca. Thus their utilization did not change in comparison with control. On the other hand, both inhibitory and stimulatory effects of 2,3,5-triiodobenzoic acid and maleic hydrazide on growth were associated with a relatively lower accumulation of the elements in question, resulting in an increased utilization.
The distribution index of N, P, K, and Ca decreased with increasing concentrations of IAA, 2,3,5-triiodobenzoic acid and maleic hydrazide. Only the highest 2,3,5-triiodobenzoic acid and maleic hydrazide concentrations used brought about a more marked increase in the distribution index of potassium, simultaneously with a marked decrease in the distribution index of calcium.
Abstract
Sledovali jsme ve vodních kulturách vliv různých koncentrací IAA, TIBA a MH přidávanych do Richterova živného roztoku na růst hrachu. Po 18 dneoh kultivace jsme hodnotili růst a ve sklizených rostlinách jsme stanovili obsah celkového N, P, K a Ca.
Růst pokusných rostlin (hodnoceno vahou svěží a suché hmoty) byl všemi třemi regulátory ovlivňován v závislosti na použité konoentraci. Nižší koncentrace růst stimulovaly, vyšší inhibovaly, přičemž všeohny použité koncentrace IAA stimulovaly tvorbu svěží hmoty i sušiny kořenového systému.
Poměr váhy sušiny kořenů váze sušiny celé rostliny (RWR) byl aplikací IAA a TIBA zvýšen, zatímco MH jej oproti kontrole neměnil. Stimulace příp. inhibice růstu vyvolaná aplikací IAA byla provázena úměrně zvýšenou nebo sníženou akumulací N, P, a Ca. Proto se také utilizace oproti kontrole neměnila.
Naproti tomu inhibiční i stimulační působení TIBA a MH na růst bylo provázeno relativně nižší akumulací zmíněných prvků, což se projevilo ve zvýšené utilizaci.
DistribuČní index N, P, K a Ca se stoupajícími koncentracemi IAA, TIBA i MH klesal. Pouze nejvyšší použité koncentrace TIBA a MH vyvolaly výraznější zvýšení DI draslíku se současně výrazným snížením DI vápníku.
