The accessions were evaluated with randomized block design, with three repetitions. Among the morphological characteristics, the bract length, and plant height were the traits that presented most variation among the accessions of P. alata, whereas floral pedicel length and internode number presented the largest variation among the accessions of P. cincinnata. By means of multivariate analysis, applying Mahalanobis's cluster technique by single linkage, Tocher optimization, and canonic variables, a cluster of the genotypes per species was noted, and within each species, there was consistency between the methods for the number of groups formed. The accessions of P. alata were divided in our subgroups and the ones of P. cincinnata in eight subgroups. From the qualitative data, the cluster analysis by means of the nearest neighbor method revealed the formation of nine groups, separating them by species, with cophenetic correlation coefficient of r cof = 86. The traits were not efficient to group the accessions, and the corona diameter was the character that contributed most for the explanation of the interspecific genetic divergence. Genetic variability was observed in and between species, with larger genetic divergence between accessions 363 and 332 of P. alata, and 245 and 211 of P. cincinnata.

An experiment was conducted to testify the hypothesis that partially UV-blocking film has the ability to suppress the development of canker disease of citrus. The quantified variables were latent period of the pathogen, temperature, relative humidity, partially UV-blocking conditions, disease incidence and disease severity. The mini houses were constructed and covered with four types of polyolefin films that have the ability to block solar UV-irradiation shorter than UV-A of (<400 nm), (<360 nm), (<350 nm) and (<340 nm) and the results were compared with UV-transmitting and outdoors. The result showed that the leaves under <400 nm and <360 nm UV-blockings took less time (8 days) to express the symptom than outdoors (13 days). The lowest incidence (66.7%) was recorded in outdoors and highest incidence (100%) was recorded under <400 nm at 45 days after inoculation. Similarly, lowest severity (10%) was recorded in outdoors and the highest severity (43.3%) was recorded under <400 nm at 45 days after inoculation. Disease incidence and severity gradually decreased as the UV blocking rates decreased. Solar radiation with contains combination of different UV-radiation may be detrimental for multiplication of the bacteria Xanthomonas axonopoides pv citri.

The environment may be mediated by artificial filming with different colored polyethylene. The mechanism of lettuce growing under colored plastic film remains largely unknown. Thus, to investigate the impact of different plastic film on the growth environment, yield parameters and phytochemical properties of lettuce, the present study was performed. Five different colored polyethylene films viz. black, white, blue, olive and silver were used as a treatment factor, in filed condition. The results demonstrated that the soil pH, temperature and overall performance of lettuce, as well as the phytochemical composition, varied within the use of different films. The maximum soil pH and temperature were found under black filming plots. Additionally, the black colored plastic film exhibited the best values for most of the yield parameters studied over other plastic films, whereas the field with non-plastic film condition showed the worst data in the experiment. Phytochemical concentrations and nutritive value of lettuce were also significantly affected by the colored plastic treatments. Furthermore, the chlorophyll, anthocyanin, phenols and carotenoids contents were increased in plants grown in soil covered with black polyethylene. Vitamin C content was of 2.5 fold higher in the plants grown in the black film compared to control conditions. The application of plastic film led to elevated concentrations of macro and micronutrients in lettuce because of the direct effect of modified radiation under the plastic film. Taken together, it can be concluded that plastic filming could be used to enhance the yield and nutritional status of lettuce in natural plant production facilities.

In this study three potato varieties; Diamant (P1), Cardinal (P2) and Asterix (P3), and two tomato varieties; Bangladesh Agricultural Research Institute (BARI) tomato-2 (T1) and BARI tomato-11 (T2) were used to make the grafted combinations T1P1, T1P2, T1P3, T2P1, T2P2 and T2P3, designated G1, G2, G3, G4, G5, and G6, respectively. Tomato seedlings aged 25 (S1) and 35 days (S2) were selected as scions. Graft compatibility was analyzed based on the growth and yield of the pomato plants. The results revealed that varieties and scion age had a significant effect on the pomato fruit and tuber yield. The initiation of flowering was not affected by the various graft combinations; however, plant height, leaf number, branch number, number of clusters per plant, number of fruit per cluster, number of fruit per plant, fruit length, fruit diameter, single fruit weight and total fruit yield per plant were higher in G5S1 among the combinations. On the other hand, the number of tubers per plant, single tuber weight, and tuber yield per plant were highest for a few combinations. Overall, it was concluded that Cardinal (P2) and Asterix (P3) potato were the most compatible for grafting with BARI tomato-11 (T2) at the scion age of 25 days (S1), based on vegetative growth and fruit and tuber yield of pomato plants.

An experiment was conducted to testify the hypothesis that partially UV-blocking film has the ability to suppress the development of canker disease of citrus. The quantified variables were latent period of the pathogen, temperature, relative humidity, partially UV-blocking conditions, disease incidence and disease severity. The mini houses were constructed and covered with four types of polyolefin films that have the ability to block solar UV-irradiation shorter than UV-A of (<400 nm), (<360 nm), (<350 nm) and (<340 nm) and the results were compared with UV-transmitting and outdoors. The result showed that the leaves under <400 nm and <360 nm UV-blockings took less time (8 days) to express the symptom than outdoors (13 days). The lowest incidence (66.7%) was recorded in outdoors and highest incidence (100%) was recorded under <400 nm at 45 days after inoculation. Similarly, lowest severity (10%) was recorded in outdoors and the highest severity (43.3%) was recorded under <400 nm at 45 days after inoculation. Disease incidence and severity gradually decreased as the UV blocking rates decreased. Solar radiation with contains combination of different UV-radiation may be detrimental for multiplication of the bacteria Xanthomonas axonopoides pv citri.

The environment may be mediated by artificial filming with different colored polyethylene. The mechanism of lettuce growing under colored plastic film remains largely unknown. Thus, to investigate the impact of different plastic film on the growth environment, yield parameters and phytochemical properties of lettuce, the present study was performed. Five different colored polyethylene films viz. black, white, blue, olive and silver were used as a treatment factor, in filed condition. The results demonstrated that the soil pH, temperature and overall performance of lettuce, as well as the phytochemical composition, varied within the use of different films. The maximum soil pH and temperature were found under black filming plots. Additionally, the black colored plastic film exhibited the best values for most of the yield parameters studied over other plastic films, whereas the field with non-plastic film condition showed the worst data in the experiment. Phytochemical concentrations and nutritive value of lettuce were also significantly affected by the colored plastic treatments. Furthermore, the chlorophyll, anthocyanin, phenols and carotenoids contents were increased in plants grown in soil covered with black polyethylene. Vitamin C content was of 2.5 fold higher in the plants grown in the black film compared to control conditions. The application of plastic film led to elevated concentrations of macro and micronutrients in lettuce because of the direct effect of modified radiation under the plastic film. Taken together, it can be concluded that plastic filming could be used to enhance the yield and nutritional status of lettuce in natural plant production facilities.

In this study three potato varieties; Diamant (P1), Cardinal (P2) and Asterix (P3), and two tomato varieties; Bangladesh Agricultural Research Institute (BARI) tomato-2 (T1) and BARI tomato-11 (T2) were used to make the grafted combinations T1P1, T1P2, T1P3, T2P1, T2P2 and T2P3, designated G1, G2, G3, G4, G5, and G6, respectively. Tomato seedlings aged 25 (S1) and 35 days (S2) were selected as scions. Graft compatibility was analyzed based on the growth and yield of the pomato plants. The results revealed that varieties and scion age had a significant effect on the pomato fruit and tuber yield. The initiation of flowering was not affected by the various graft combinations; however, plant height, leaf number, branch number, number of clusters per plant, number of fruit per cluster, number of fruit per plant, fruit length, fruit diameter, single fruit weight and total fruit yield per plant were higher in G5S1 among the combinations. On the other hand, the number of tubers per plant, single tuber weight, and tuber yield per plant were highest for a few combinations. Overall, it was concluded that Cardinal (P2) and Asterix (P3) potato were the most compatible for grafting with BARI tomato-11 (T2) at the scion age of 25 days (S1), based on vegetative growth and fruit and tuber yield of pomato plants.
