Effects of flowering and production inducers in the Mexican lime (Citrus aurantifolia Swingle)

Abstract

Objective: To evaluate new hormonal and biostimulant products to induce flowering of Mexican lime (Citrus aurantifolia Swingle) for winter production at the state of Guerrero, Mexico. Design/methodology/approach: Prohexadione calcium (PHD-Ca), cytokinins, paclobutrazol, biuretic urea, granulated urea (46%) and a control were evaluated. Results: There are differences between treatments for the number of flowers and number of fruits (Pr>0.0411 and 0.048); regard the “number of flowers” variable, paclobutrazol, prohexadione calcium and granulated urea (46%) stood out; while, prohexadione calcium, paclobutrazol and cytokinins favor the “number of fruits” variable. The yields show statistical differences (Pr>0.0332) and the cytokinins and paclobutrazol stood out. Findings/conclusions: The usage of cytokinins for induction and winter production of Mexican lime is suggested.

Climatic Factor Differences and Mangosteen Fruit Quality between On- and Off-Season Productions

“…Many studies have reported that drought can induce flowering in several plant species, including durian [10,11], mango [15], citrus fruits [9], longan [13], lime [12], loguat [14], and mangosteen [17]. A drought period lowers soil moisture and increases soil temperature.…”

“…Many studies have shown that mangosteen reproductive phenology (i.e., flowering and fruiting) is associated with climatic conditions (e.g., rainfall, temperature, radiation levels, and photoperiod), height above sea level, availability of shade, and geographical locations [2][3][4][5][6][7][8]. Drought-inducing flowering has been reported in several plant species, including citrus fruits [9], durian [10,11], lime [12], longan [13], loguat [14], mango [15], and mangosteen [5,16,17]. Many studies have reported that drought-inducing flowering in mangosteens with 15-30 dry days for flower bud formation and flowering, occurs naturally after the dry period [2,3,5,[17][18][19].…”
