Exogenously applied jasmonic acid induces changes in apical meristem morphology of potato stolons.
Hooked apex stolons and initial swelling stolons of potato plants were treated with 3 x 10-8 mol l-1 jasmonic acid (JA) to study the effect of this compound on histology, cell expansion and tissue differentiation. In hooked apex stolons, JA application increased the meristem thickness and reduced the length of the leaf primordia, whereas in initial swelling stolons narrowing of the apical regio...
متن کاملStudies on the carbon dioxide promotion and ethylene inhibition of tuberization in potato explants cultured in vitro.
Ethylene inhibited the tuberization of etiolated potato (Solanum tuberosum L. var. Red La Soda) sprout sections cultured in vitro. Carbon dioxide did not overcome the C(2)H(4) inhibition but it was required for normal tuberization. Ethylene totally prevented root formation and development. It inhibited stolon elongation, and caused thickening and diageotropical growth of the stolon. In addition...
متن کاملIn Vitro Tuberization of Potato Influenced by Benzyl Adenine and Chloro Choline Chloride
In an experiment, six levels of benzyl adenine (0.2.5,5.0,7.5,lO.0,12.5 and 15.0 mg/I) in combination with three levels of (CCC) chloro choline chloride (0,125,250 and 500 mg/I) were evaluated against control treatment (0) in each case to find out their optimum levels for microtuberization in potato variety Diarnant. Microtuberization was the earliest by I 3 days at 10 mg/I BA. The number and a...
متن کاملGraft-transmissible induction of potato tuberization by the microRNA miR172.
The photoreceptor phytochrome B (PHYB) and the homeodomain protein BEL5 are involved in the response of potato tuber induction to the photoperiod. However, whether they act in the same tuberization pathway is unknown. Here we show the effect of a microRNA, miR172, on this developmental event. miR172 levels are higher under tuber-inducing short days than under non-inductive long days and are upr...
متن کاملEffects of paclobutrazol and jasmonic acid on potato minituber production and some plant characteristics in aeroponic cultivation system
In this research, the acclimatized in vitro plants were transferred to the aeroponic system and the effects of paclobutrazol (PBZ) and jasmonic acid (JA) were investigated on the production of potato (Solanum tuberosum L. cvs Agria and Svalan) minitubers. Some plant characteristics were also investigated in this cultivation system, under greenhouse conditions. Plants were foliar sprayed with PB...
