“…These findings were different from the results of Vrbničanin et al . (). They reported that C. campestris infection negatively affected several parameters of chlorophyll fluorescence of its host, A. trifida , in the absence of drought stress.…”

“…Several parameters of the leaf Chl a fluorescence of the host, Ambrosia trifida , such as minimal and maximal fluorescences and electron transport rates, also were influenced by the parasitism of C. campestris (Vrbničanin et al . ). Thus, C. campestris infection appears to suppress host photosynthesis by limiting gas diffusion via stomatal and photosynthetic metabolic processes.…”

Cuscuta species (dodders) are widespread stem holoparasites that depend on host plants for their entire mineral and water and most carbohydrate requirements. Dodders negatively affect host photosynthesis but precise information on their impact on hosts in the presence of environmental stress factors (i.e. drought) is little known. In a pot experiment, the leaf traits, gas exchange and chlorophyll a fluorescence of the invasive climber, Mikania micrantha, parasitized by Cuscuta australis, were investigated in order to study variations of host photosynthesis in response to parasitism and drought. The results showed that the concomitant presence of C. australis infection and drought significantly impacted the leaf traits (i.e. increased leaf dry mass content), gas exchange (i.e. decreased stomatal conductance and transpiration rates and increased water-use efficiency) and quantum yield of chlorophyll a fluorescence of M. micrantha. The presence of a single stress factor (C. australis infection or drought), however, only significantly affected the leaf traits and gas exchange of M. micrantha. These results suggested that the combined additive effects of C. australis parasitism and drought significantly suppressed the photosynthesis of M. micrantha in relation to both stomatal and non-stomatal limitation of host photosynthesis. This study provides insights into Cuscuta-host interactions under drought conditions in the tropics.

“…Striga infection did not affect chlorophyll fluorescence (Tables 8 and 9), and this probably indicated that all maize genotypes were able to maintain normal rate of photosynthesis under Striga infestation. Striga infection reportedly reduces rates of photosynthesis because of photoinhibition caused by Striga (Gurney et al, 2002b; Baker and Rosenqvist, 2004; Mauromicale et al, 2008; Vrbničanin et al, 2013), photoinhibition being the inactivation of the photosystem II photochemistry reaction center, which causes a reduction in rates of photosynthesis (Gurney et al, 2002b). Similarly, Striga ‐infested genotypes had a significantly wider ASI than noninfested ones (Table 9).…”

Striga asiatica (L.) Kuntze, an obligate hemiparasite, can cause grain yield loss of 20 to 80% in cereal crops such as maize (Zea mays L.). In Sub‐Saharan Africa, maize breeding programs have focused on productivity of normal endosperm maize under Striga infestation while neglecting quality protein maize (QPM). This study aimed at determining levels of resistance or tolerance of eight new QPM genotypes and four non‐QPM checks to Striga asiatica in the field, pot, and agar gel experiments. Under field conditions, genotypes were evaluated in three different Striga‐endemic locations during the 2014–2015 and 2015–2016 cropping seasons using a four‐by‐three α‐lattice design with three replications. In the pot experiment, genotypes were arranged in 12 × 2 factorial treatments in a six‐by‐four α‐lattice design replicated four times. In the agar gel experiment, genotypes were arranged in a randomized complete block design replicated four times. In the field experiment, genotype × environment interaction was significant (p < 0.001) for grain yield, and MQ623, SC643, SC527, and SC535 were high yielding and more stable than non‐QPM genotypes. In the pot experiment, these genotypes also exhibited desirable Striga tolerance, whereas variation was significant (p < 0.05) for Striga treatments and genotype main effects, as well as for Striga × genotype interaction for root biomass and root/shoot biomass ratio. Five QPM genotypes (MH1416, MQ623, SC643, SC527, and SC535) produced higher and more stable grain yields than most of the non‐QPM checks in Striga‐infested fields. These genotypes provided alternative QPM sources that can perform relatively well in Striga‐endemic areas.

“…The growth of field dodder was faster than that of Mikania micrantha, an invasive alien plant in China, and damage caused by field dodder qualified it a biological agent to control M. micrantha (Deng et al 2003;Zan et al 2003;Zhang et al 2004;Li et al 2012). Similarly, field dodder was found promising in control of Ambrosia trifida, an invasive alien plant in Europe (Vrbnicanin et al 2013).…”

Field dodder (Cuscuta campestris Yunck.) is a very harmful parasitic weed species worldwide which infests many crops, including alfalfa as a foremost forage crop. Glyphosate has been an effective herbicide for field dodder control even though side effects occasionally occur in alfalfa plants. To find out and quantify the effects of glyphosate (288 and 360 g a.i. ha-1) on field dodder control, alfalfa forage yield, and physiological and anatomical features of alfalfa plants under controlled conditions were aims of the study. Physiologic (chlorophyll a, chlorophyll b, total carotenoids); and anatomic parameters were measured. Leaf anatomic parameters were thicknesses of upper epidermis, palisade and spongy tissues, mesophyll and underside leaf epidermis, and diameter of bundle sheath cells. Stem anatomic parameters were thicknesses of epidermis and cortex, and diameters of stem and central cylinder (pith). Both rates of glyphosate caused recovery of the harmful effects of field dodder on alfalfa, which shows that glyphosate can control field dodder at early stages of infestation on alfalfa.
