Tomato (Lycopersicon esculentum Mill.) plants heterozygous for the diageotropica (dgt) mutation exhibit a unique phenotype, termed ;mottled.' Unlike dgt, mottled individuals grow upright, exhibit normal root branching, and produce normal levels of ethylene in response to applied auxin. Leaves of mottled plants are deformed and reduced in size and are characterized by a mottled appearance on the...

The mechanism of chilling resistance was investigated in 4-week-old plants of the chilling-sensitive cultivated tomato, Lycopersicon esculentum Mill. cv H722, and rooted cuttings of its chilling-resistant wild relative, L. hirsutum Humb. and Bonpl., which were chilled for 3 days at 2 degrees C with a 14-hour photoperiod and light intensity of 250 micromoles per square meter per second. This chi...

Drought causes an increase in some gene expression in plant tissues such as plasma membrane intrinsic proteins type 1 (PIP1), 9-cis-epoxycarotenoid dioxygenase (NCED) SlAREB1. The effects of exogenous abscisic acid (ABA) and two sulfonamide compounds, namely, sulfacetamide (Sa) and sulfasalazine (SS) were studied on gene expression of tomato (Lycopersicon esculentum Mill. Cv. Super chief) under...

Cilj istraživanja bio je utvrditi alelopatski potencijal lucerne (Medicago sativa L.) na klijavost sjemena i rast klijanaca rotkvice (Raphanus sativus L.), radiča (Cichorium intybus L. var. foliosum) rajčice (Lycopersicon esculentum Mill.). Vodeni ekstrakti pripremljeni od suhe nadzemne mase u tri koncentracije (1 %, 2,5 % 5 %) testirani su laboratorijskim uvjetima. Alelopatski ovisio o test vr...

Estimation of Cardinal Temperatures for Tomato (Solanum lycopersicom) Seed Germination Using Nonlinear Regression Models

two-spotted spider mite (tssm) is becoming resistant to many of the pesticides used in the tomatofields. a potential alternative method of control is host plant resistance, which may be mediated byglandular trichomes. in this experiment, level of entrapment and mortality of the pest by type ivglandular trichomes were studied on accessions of lycopersicon hirsutum humb & bonpl, l. pennellii(cor....
