Effects of Water Deficit and Manure on Yield and Morphological Characters Some of Dragonhead (Dracocephalum moldavica) in Jiroft Area

In this research effect of drought (water deficit) stress and manure on yield and some of the morphological characters of dragonhead was studied. In this study a strip plot pot experiment based on randomized complete block design (RCBD) was conducted in greenhouse with 15 treatments and 3 replication, in the Islamic Azad University Jiroft Branch in Iran during 2009. Three levels of water stress at 75% Fc (least stress), 50% Fc (moderate stress) and 25% Fc (severe stress) were considered as vertical factor and five manure levels (0 – 10 – 20 – 30 – 40 t/ha) were considered as horizontal factor. Total fresh and dry herb yield, plant height, number of stem, internode length, dry leaf and dry stem weights were measured. The results showed that the effect of water deficit stress on all morphological characters, except inter node length and stem number, were significant (= %5). The effect of manure on all morphological characters, except inter node length, were significant (= %5, = %1). Fresh and dry weights of herb, number of stem, plant height, dry leaf and stem weights decreased by increasing water stress. Water stress, significantly reduced on herb yield from 4868.27 kg/ha to 3348.00. Maximum dry herb yield with 4956kg/ha was due to 75% Fc (least stress) with manure treatment of 40 t/ha. Results of this study showed that by increasing manure level dry herb yield was increased. A significant positively correlation between dry herb yield and fresh herb (r = 0.969), number of stem (r = 0.849), plant height (r = 0.684), dry leaf (r = 0.969), dry stem (r = 0.974) were observed

Effect of training the communication skills with cognitive-behavioral model to drug dependent couples on communication patterns and recurrent relapse

Background: One of the main challenges in methadone maintenance treatment is relapse and lack of sustainability on treatment. Therefore, considering the effective factors in this regard and reducing it through psychological interventions as an adjunct to medication is necessary. Objective: The current study aimed to determine the effectiveness of communication skill training based on cognitive-behavioral model on communication patterns and recurrent relapse in drug dependent couples. Methods: This study was a quasi-experimental intervention with pretest-posttest and control group in 2013 which carried on 40 couple referred to public addiction treatment center of Qazvin city. These people had troubled communication patterns and were selected using convenience sampling and were divided into two groups of intervention and control, randomly. Two groups were assessed by relapse prediction scale (RPS) and structured clinical interview for DSM (SCID-I) for men and communication pattern questionnaire (CPQ) for couples in pre and post-test. Intervention group received 9 two hours sessions of communication skill training based on cognitive-behavioral model. Data were analyzed using Levin and Box tests and multivariate analysis of covariance (MANCOVA). Findings: The difference between the intervention and control groups in the constructive communication pattern with 51% (p<0/05), in mutual avoidance pattern with 61% (p<0/0001) and in the demand / withdraw pattern with 45% (p<0/05) was statistically significant. Also, the difference between the two groups in the rate of relapse with 64% (p<0/0001) was statistically significant. Conclusion: According to the findings it seems group training of communication skill based on cognitive-behavioral model can improve the communication patterns in drug-dependent couples, as well as prevents relapse in men

Chlorophyll fluorescence imaging

Chlorophyll fluorescence imaging provides a noninvasive rapid screen to assess the physiological status of a number of leaves or plants simultaneously. Although there are no standard protocols for chlorophyll fluorescence imaging, here we provide an example of routines for some of the typical measurements
